Lock can be manually operated with a hexagon wrench.

Can be easily mounted onto equipment

Separable construction for improved ease of maintenance

The lock unit and the cylinder can be separated.
This allows for easier maintenance.

Holding force improved by 15%

MNB, ø50: 1370 N a MWB: 1570 N

Overall length reduced by 18 mm max.

Up to 18 mm shorter compared with the MNB series

Compact auto switches are mountable.

Part numbers for products with a rod end bracket and/or a pivot bracket are available.

It is not necessary to order a bracket for the applicable cylinder separately.

* Rod end brackets and pivot brackets are shipped together with the product, but not assembled.

Series Variations

Lock Unit

A safety mechanism can be designed if required.
It can also be combined with a wide variety of actuators.
