Q1: Is the seal set for the CA1 cylinder available?
A1: Yes, the seal set for CA1 cylinders is generally available. BDC Singapore can provide compatible seal kits through authorized pneumatic component suppliers in Singapore. It is recommended to confirm the specific cylinder model (including bore size and stroke) when placing an order to ensure the seal kit matches. For urgent needs, we can coordinate with local warehouses to shorten the delivery cycle.
Q2: What is the part no. of seal kit for CQ2B50-30DC?
A2: The standard seal kit part number for the CQ2B50-30DC cylinder is typically SCS-CQ2B50 (subject to the original component brand). BDC Singapore can assist in verifying the exact part number with the brand supplier (such as SMC) and provide procurement services. When replacing the seal kit, please use lithium soap-based grease (equivalent to JIS2 grade) to apply on the sealing surface to avoid damage during installation <superscript:2].
Cylinder Model Differences & Replacements
Q3: What is the difference between the CA1 cylinder and CA2 cylinder?
A3: The core differences between CA1 and CA2 cylinders lie in structural design and application scenarios: ① CA1 cylinders are standard compact cylinders with a simple structure, suitable for general load-bearing occasions and cost-sensitive projects; ② CA2 cylinders are upgraded models with optimized sealing performance and higher durability, equipped with enhanced piston guides to adapt to high-frequency operation and slightly harsh working environments. In addition, CA2 series may offer more optional configurations (such as built-in magnets) than CA1.
Q4: We would like to replace CDQ2B32-30D during maintenance. What is the part no. of the current product, which is a replacement?
A4: The replacement product for CDQ2B32-30D is the upgraded model CDQ2B32-30D-Z (compatible with the original installation dimensions). The part number remains consistent with the original model for direct replacement. BDC Singapore can provide the latest replacement model specifications and ensure compatibility with existing pipelines and mounting structures to minimize maintenance downtime.
Auto Switch Related
Q5: CA2B80-50Z does not have a magnet on its piston. Does this mean it is impossible to use auto switches with this cylinder?
Q6: We are going to replace CDQ2B50-30DC-A73 during maintenance. What should we do to attach a D-A73 autoswitch to an existing CQ type cylinder, without changing this autoswitch?
A6: To attach the D-A73 auto switch to an existing CQ-type cylinder, please follow these steps: ① Confirm that the existing CQ cylinder piston has a built-in magnet (a prerequisite for using D-A73); ② Install the switch bracket matching the CQ cylinder's bore size on the cylinder tube; ③ Fix the D-A73 auto switch on the bracket and adjust the position according to the required signal trigger point; ④ Connect the switch wires to the control circuit and test the signal stability. BDC Singapore can provide matching brackets and on-site guidance if needed.
Q7: We were informed by supplier that a switch is not included with the CDQ2B20-10DZ-M9B. Why is this?
A7: The CDQ2B20-10DZ-M9B cylinder is supplied without an auto switch because it is designed as a "basic cylinder model" with optional switch configurations. The "Z" in the model indicates that the piston has a built-in magnet (supporting magnetic auto switches), but the switch itself is not a standard accessory. This design allows customers to select switches of different types (such as M9B, A73) according to actual control needs. BDC Singapore can provide matching auto switches and one-stop procurement services.
Fittings & CAD Data
Q8: Are there any double clevis fittings for the CQ2D20-25DM?
A8: Yes, double clevis fittings compatible with CQ2D20-25DM cylinders are available. The recommended part number is Y clevis fitting (model: CQ2-CLEVIS-D20) with matching pins and cotter pins. BDC Singapore can provide fittings that comply with Singapore industrial standards, ensuring stable connection and load-bearing capacity. It is recommended to check the fitting's material (steel or aluminum alloy) according to the working load.
Q9: We would like to download the 2DCAD data for CQ2_40Ф, but only CQ2-Z is available. Is it all right to use it?
A9: It is acceptable to use the 2DCAD data of CQ2-Z for CQ2_40Ф cylinders if the core dimensions (bore size, mounting dimensions, stroke range) are consistent <superscript:4]. The "Z" in CQ2-Z mainly indicates the magnetic piston function, which does not affect the external structural dimensions. However, if the design involves internal piston structure or switch installation positions, BDC Singapore recommends verifying the dimensional parameters with the original brand's technical manual to avoid design deviations.
MY Series Rodless Cylinders
Q10: Is a procedure available to replace the dust seal band of the MY* series?
A10: Yes, there is a standard procedure for replacing the dust seal band of MY* series cylinders. The key steps are: ① Disassemble the cylinder end caps and remove the carriage; ② Use a special tool to take out the old dust seal band (avoid scratching the cylinder tube surface); ③ Apply lubricating grease to the new dust seal band and install it in the seal groove; ④ Reassemble the carriage and end caps, and test the cylinder movement for smoothness. BDC Singapore can provide detailed operation manuals and professional maintenance tools.
Q11: Is the intermediate stroke of the MY∗ series available with the special exclusive body or is the stroke adjusted by using a spacer?
A11: The intermediate stroke of MY* series cylinders is mainly adjusted by using spacers, and special exclusive bodies are not required for general stroke adjustment. Spacers of different thicknesses can be installed at both ends of the cylinder to limit the piston stroke, achieving the required intermediate stop position <superscript:3]. For precise stroke control, BDC Singapore recommends matching with limit switches to ensure positioning accuracy. It should be noted that the adjusted stroke should reserve a 1-2mm safety margin to avoid piston collision <superscript:5].
Q12: How do you configure a circuit in order to achieve intermediate stops of the mechanically jointed type rodless cylinders (MY∗ series) by using valves?
A12: To achieve intermediate stops of MY* series rodless cylinders via valve configuration, adopt the following circuit design: ① Use a 5/3-way middle-sealed solenoid valve to cut off the air supply to both sides of the cylinder when the valve is in the neutral position, realizing mechanical locking; ② Configure speed control valves on both air inlet/outlet paths to adjust the cylinder movement speed and ensure stable stopping; ③ Match with position sensors (such as proximity switches) to send stop signals to the solenoid valve. BDC Singapore can provide circuit diagrams and component selection suggestions based on specific control requirements.
Q13: What are the differences between the MY series?
A13: The MY series rodless cylinders mainly differ in connection mode, load capacity and sealing performance: ① MY1B: Mechanically jointed type, suitable for medium and light loads, with simple structure and easy maintenance; ② MY2B: Double-slider mechanically jointed type, capable of bearing larger lateral loads, suitable for multi-point transmission occasions; ③ MY3B: High-precision type, with optimized guide structure and low friction coefficient, suitable for precision positioning scenarios. In addition, different sub-models may have differences in sealing materials and corrosion resistance to adapt to different working environments.
CY Series Cylinders
Q14: Have the CY1B and CY1S already completed a model change?
A14: Yes, both CY1B and CY1S series cylinders have completed model upgrades. The upgraded models are CY1B-Z and CY1S-Z respectively, which are fully compatible with the original installation dimensions and have improved reliability and service life. BDC Singapore only supplies the upgraded Z-series products currently and can provide replacement guidance for customers using old models.
Q15: For CY1S-Z which replaces CY1S, is it necessary to select the type of magnet holding "H" or "L" on the model number?
A15: Yes, it is necessary to select the magnet holding type ("H" or "L") for CY1S-Z cylinders. "H" represents high magnetic holding force, suitable for occasions requiring strong adsorption and stable positioning; "L" represents standard magnetic holding force, suitable for general control scenarios <superscript:6]. The selection should be based on the weight of the carriage load and the required positioning stability. BDC Singapore can assist in determining the appropriate type according to the actual application scenario.
Q16: Why does the carriage of the CY1S product operate completely to one end of the stroke, but at the other, stops before reaching the end?
A16: This phenomenon is mainly caused by the following reasons: ① Uneven air pressure supply: Check whether the air pressure on both sides of the cylinder is balanced, and clean or replace the air filter and pressure reducing valve if necessary; ② Mechanical resistance: The guide rail or carriage is stuck due to dust accumulation or insufficient lubrication, requiring cleaning and lubrication; ③ Stroke limit deviation: The limit block or spacer is loose, needing to adjust and fasten the limit component; ④ Internal leakage: The cylinder seal is worn, leading to pressure loss on one side, which requires replacing the seal kit. BDC Singapore can provide on-site inspection and maintenance services if needed.
Q17: Is it possible to produce intermediate cylinders for CY∗ series?
A17: The CY series cylinders do not support customized intermediate stroke production as standard. For intermediate stop requirements, it is recommended to use the following solutions: ① Adjust the stroke by installing limit spacers (similar to the MY series); ② Configure a precision positioning system with solenoid valves and position sensors to achieve intermediate stops; ③ Replace with a rodless cylinder series (such as MY series) that is more suitable for intermediate stroke control. BDC Singapore can provide customized solutions based on specific working conditions.
