ACCURATE TORQUE

The drag torque is produced by means of a hysteresis principle. This allows for constant torque levels and eliminates the possibility of high break away torque that occurs with typical friction devices.

LONG OPERATIONAL LIFE

Permanent magnets and magnetic particles transmit toque, therefore, wear is virrutally eliminated.

AVAILABLE IN TWO TYPES

The standard OPL units (N type) come with an integral shaft. This shaft can be lengthened, shortened or adapted to suit a customer’s requirements, such as D cuts, snap ring grooves and others. The shaft material is 400 series stainless steel.

The second option if for OPL units to be supplied with a thru-bore (R type). Smaller bore units are available in 6mm and 8mm, larger units are only available with an 8mm bore.

STABLE TORQUE

A virtual consistent torque is maintained because of the hysteresis principle and is consistent within allowable speed range.

EASY INSTALLATION WITH NO ADJUSTMENTS

Units are provided pre-assembled to a specific torque range so there is nothing to adjust.

BEARING AND BUSHING STYLES AVAILABLE

For slower speeds and lighter loads bushing units are the most cost effective option. However, ball bearing (B) units are available if required by application speed or loading.

NO CONTAMINATION

Units are sealed which prevents any particles from contaminating the machine, and also prevents contamination of the clutch by the machine environment.
