Description

RA series solid rotary pneumatic cylinders are precision-manufactured with high-strength alloy steel, the standard matching pneumatic actuator for lathe solid power chucks.
  1. Solid body structure provides excellent rigidity and stability, delivering consistent and reliable pulling force for solid chucks.
  2. Double-acting piston design ensures fast and smooth clamping and unclamping actions, improving production efficiency.
  3. High dynamic balance design, maximum rotating speed up to 6000rpm, suitable for high-speed precision turning operations.
  4. Built-in high-performance sealing system effectively prevents air leakage and extends service life.
  5. Standard thread connection specification, directly compatible with mainstream 6/8/10/12 inch solid pneumatic chucks on the market.
  6. Compact overall design saves installation space and facilitates rear mounting and maintenance on lathe spindles.
