About Magnetically Coupled Rodless Cylinder

Owing to our rich industry experience and knowledge, we are offering a wide array of Rodless Cylinders. The offered cylinders are suitable for long stroke applications and also for use in confined areas. We assure our clients that the offered cylinder is fabricated using superior quality raw material and cutting-edge technology at vendors end. The offered cylinders are well-known among clients for their smooth & accurate functioning, corrosion resistance, adjustable cushion, longer functional life and easy operation.

Efficient Magnetically Coupled Motion

This cylinder utilizes rare-earth permanent magnets for smooth, non-contact motion transfer between the external carriage and internal piston. The rodless design enables space-saving installation and extended stroke lengths without compromising precision, making it suitable for applications where conventional cylinders are limited.

Precision and Versatility in Industrial Automation

With adjustable cushioning at both ends and high repeatability (0.1 mm), the cylinder ensures gentle, precise stops even at speeds up to 2 m/s. Multiple bore sizes, customizable lengths, and optional mounting accessories allow adaptation to diverse automation requirements across manufacturing and processing lines.

Maintenance-Free Operation for Reliability

Factory pre-lubrication and robust sealing (polyurethane/NBR or FKM) guarantee maintenance-free performance and a low leakage rate (<0.2 ml/min). The durable extruded aluminum barrel and stainless steel carriage contribute to long service life even in demanding environments.

FAQs of Magnetically Coupled Rodless Cylinder:

Q: How does the magnetic coupling in this rodless cylinder work?

A: The actuator uses embedded rare-earth magnets inside the piston and external carriage, ensuring a secure, non-contact force transmission. This allows the carriage to follow the pistons motion smoothly without external rod protrusion, reducing space requirements and potential contamination.

Q: What are the benefits of the adjustable pneumatic cushioning at both ends?

A: Adjustable cushioning allows you to fine-tune the cylinders stopping characteristics, minimizing shock and vibration at end positions. This not only extends component life but also enhances positioning accuracy and process stability, particularly in fast-cycle or delicate applications.

Q: When should I use the standard slide and fix mounting versus foot or flange options?

A: The standard slide and fix mounting is suitable for most applications due to its simplicity and stability. However, if your setup demands frequent repositioning, extra support, or requires a specific mounting surface, the foot or flange options provide additional installation flexibility.

Q: Where can I install magnetic proximity sensors, and what is their advantage?

A: The cylinder features an integrated sensor slot along its body, designed for easy installation of magnetic proximity sensors. These sensors enable non-contact position feedback, facilitating seamless automation and precise motion control within your system.

Q: What process steps are needed for maintenance of this cylinder?

A: This cylinder is pre-lubricated at the factory and designed for maintenance-free operation under normal conditions. Routine visual inspections for physical damage and sensor integrity are recommended, but regular lubrication or internal servicing is unnecessary.

Q: How do I select the correct port size and bore for my application?

A: Port size and bore selection depend on required thrust force, speed, and available supply pressure. For light tasks, a 16 mm bore with M5 port may suffice; for heavier loads up to 1000 N, a 40 mm bore with a G1/4 port is appropriate. Review your systems needs and consult the manufacturer for precise capacity data.

Q: What advantages does the rodless cylinder provide over traditional rod-style actuators?

A: Rodless cylinders offer longer, unobstructed strokes within a compact footprint, with no external rod to limit travel or risk contamination. This makes them ideal for applications requiring extended motion within tight spaces and high repeatability.
