- Manufactured for 25mm, 30mm, 40mm, 50mm and 60mm shaft sizes.
- ROLLERBRAKE™has no effect on the normal operation of the conveyor roll.
HOW THE ROLLERBRAKE™ WORKS
- When the ROLLERBRAKE™has been installed and running in the normal direction, centrifugal forces ensure that the ROLLERBRAKE™ units run frictionless as the pin-bearings we use seats themselves in the highest point of the cam designed in the metal housing.
- The shaft ensures that the bearing remains stationary while the metal unit attached to the idler continues moving.
- When the belt snaps or the belt is switched off the cams designed within the ROLLERBRAKE™ metal unit causes friction on the pin-bearings which are forced onto the shaft braking the idler.

ROLLERBRAKE™ IN THE FIELD
The required quantity of ROLLERBRAKE™ is calculated from the data captured on the
Information Specification Sheet (ISS Download PDF) from which a suggested layout pattern
is then formulated and provided. This Information Specification Sheet must be accurately
completed and forwarded on to the relevant contract holder or approved manufacturer.
Coverage will vary under the following belt conditions:
- Belt length along incline
- Conveyor Angle
- Average belt speed under load
- Tonnage per hour
- Conveyor belt width
- Average idler spacing along incline
- Number of rolls per idler frame
- Idler unit outside diameter
- Idler unit face length
- Idler frame trough angle
