Corrosion-resistant construction with IP54 protection rating makes it suitable for harsh environments. Requires 5μm filtered compressed air with lubrication (ISO VG32 recommended).
- Precision press-fit operations in electronics assembly
- Variable height positioning in CNC tool changers
- Force-controlled clamping systems
- Packaging machine product height compensation
- Semiconductor wafer handling robots
Installation tip:
Use locknuts on both sides of adjustment collar during installation.
Perform stroke calibration after every 50,000 cycles. Lubricate guide shafts
with silicone grease (NLGI #2) monthly in high-cycle applications.
