ISO 21287 | UNITOP Pneumatic Stopper Cylinder - Series ST

Email Us

Pneumatic stopper cylinders are specifically designed to halt moving parts within automation systems, effectively stopping the load once the desired position is achieved.

Available as either UNITOP or ISO 21287, ST stopper cylinders are ideal for locking applications where safety, long life, reliability, and high static holding forces are essential.

A large-diameter, hardened, chromed stainless locking bolt provides a high lateral force load-bearing capacity for locking or stopping applications, offering extreme strength and durability.

These cylinders are available in various versions to accommodate different stopping or locking conditions.

They feature a robust design with bore sizes ranging from 20 mm to 80 mm, and users can choose between single-acting and double-acting configurations.
