Application example
Basic Freewheel FGR 25 R as a backstop on a reduction gear in the drive of an inclined conveyor of an assembly train. When the unit stops, the conveyor belt must be held securely so that it does not run backwards by the weight of the assembly parts. A brake disk is fitted to the outer ring of the freewheel alongside a manually operated brake calliper. The back driving torque is maintained by the freewheel and the closed brake. During set-up it must be possible to move the installation in both directions of rotation. To do this, the brake caliper is opened manually.
The customer connecting parts are centered on the ball bearing external diameter F and
assembled via the outer ring. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter F of the connecting part must be ISO H7 or J7. The centering depth C must be observed.
An oil lubrication of the specified quality must be provided. Two flat seals are supplied for
sealing between the faces of the outer ring and the connecting parts.
