Cylinder With Lock, Double Acting, Single Rod MNB Series (Part Numbers)

Cylinder With Lock, Double Acting, Single Rod MNB Series

A standard cylinder that can be locked in both directions.
[Features]
· An air cylinder with lock. Suitable for intermediate stops, emergency stops and drop prevention.
· Uses the wedge effect to magnify the force applied to the taper ring and steel balls.
· Can be used from 50 to 1,000 mm/s if within the allowable kinetic energy range.
· High locking efficiency. Structured so as not to be impacted by the quality of the lock-release air.
· Manual override for unlocking.
· High reliability and stable holding force.
*See the SMC catalog for specification details.
*Product pictures are representative images. CAD data is not supported for some model numbers.

Spring lock (exhaust locking)

The spring force that acts on the taper ring is magnified by a wedge effect, and is conveyed to the numerous steel balls that are arranged in 2 rows. These act on the brake shoe holder and brake shoe, which locks the piston rod by tightening it using a large force.
Unlocking is accomplished when air pressure is supplied to the unlocking port. The brake piston and taper ring oppose the spring force, moving to the right side, and the ball retainer strikes cover section A. The braking force is released as the steel balls are moved away from the taper ring by the ball retainer.
