SR2 for holding and locking motion

This is a new clutch mechanism that allows you to easily lift and lower heavy
objects and hold them in any position.

BENEFIT
Control devices such as "electromagnetic clutches, actuators, and solenoids"
require electrical power, however, SR2 can operate without it.

Product information

Typical rotary dampers operate faster when the torque from the application
is higher than the preset torque and slower when the torque from the application
is lower than the preset torque. However, SR3 maintains a constant damping
speed through automatic torque adjustment.

‐ Opening angle: 120°
‐ Product weight: Approx. 60 g
‐ Allowable radial load (P): 29.4 N
