PS4 / PN4 SERIES

PU Pneumatic
Tie Rod Cylinder

A polyurethane-sealed tie rod cylinder built on the same rugged tie-rod platform as the CS4/CN4 range — the PS4 follows ISO 15552 / VDMA 24562 mounting, the PN4 follows ISO 6431 / CETOP RP43P, RP53P, with a high-temperature option to 150°C.

Why PU-Sealed

When To Choose PS4/PN4 Over CS4/CN4

The PS4/PN4 platform shares the CS4/CN4 body dimensions and mounting hardware, but uses a polyurethane seal package tuned for dry-running, low-lubrication and dusty environments — and unlocks the optional +150°C Viton high-temperature build for near-furnace and thermal process duty.
