- CNC turret punch press overtravel protection
- Die-casting machine ejection system shock absorption
- High-speed packaging conveyor emergency stop buffers
- Automotive assembly line fixture positioning
Installation guidelines:
Mount with 1-2mm preload compression for optimal performance.
Perform initial 50 break-in cycles before final adjustment.
Requires annual oil replenishment (5±0.5ml ISO VG15) under normal use.
Avoid lateral forces exceeding 50N.
Not suitable for continuous side-load applications.
Maintain 15mm clearance around buffer body for heat dissipation.
