A precision rotary clamping cylinder combining linear motion with 90° rotation through integrated rack-and-pinion gearing. Features dual-position mechanical locking for zero drift during machining operations. The hardened stainless steel shaft and wear-resistant seals ensure 500km+ service life under continuous operation. Requires filtered air (5-40μm) with ISO VG32 lubricant.
- CNC machine tool fixture positioning
- Automotive welding jig clamping
- Robotic arm end-effector tool changing
- Electronics assembly press-fit mechanisms
- Plastic injection mold locking systems
Installation note:
Maintain 0.5mm minimum clearance between clamp arm and workpiece surface.
Lubricate guide slots every 2,000 cycles using silicone-free grease.
Avoid side-load forces exceeding 30N during operation.
