Electromagnetic clutches and brakes from jbj Techniques Limited

Easy InstallationWithNoAdjustments. 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. BearingAndBushing StylesAvailable. 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. Units are sealed which prevents any particles from contaminating themachine, and also prevents contamination of the clutch by themachine environment. 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 type). Smaller bore units are available in 6mmand 8mm, larger units are only available with an 8mmbore. Accurate Torque. Low cost slip clutch design for momentary and/or continuous slipping. Torque is produced magnetically eliminating the possibility of high break away torque that occurs within typical friction devices. Torque is consistent over a given speed range. Units are sealed so that internal particles cannot contaminate machine likewise external particles cannot contaminate the OPLs. Units are supplied with stainless steel shafts, which can be customized to meet your needs. (The OPR units are hollow boremounted.) Stable Torque. Avirtual consistent torque is maintained because of the hysteresis principle and is consistent within allowable speed range. Units are provided pre-assembled to a specific torque range so there is nothing to adjust. No Contamination. Available In Two Types. Permanent magnets andmagnetic particles transmit toque, therefore, wear is virutally eliminated. LongOperational Life.
