Durable, reliable conveyor roller for wear issues
The Rubber Discs avoid the build up of material that can be deposited onto the roller surface which can cause the roller diameter to develop an irregular worn surface and change shape. This is often a major cause of belt mistracking. Highly effective, PROK Rubber Disc rollers are a reliable and simple maintenance solution to this common belt conveyor problem.
Ideal solution for areas where return rollers are subject to high carry back volumes and where return rollers are subject to high shell wearing.

Housing elimination for reliable performance
Custom bored tubes eliminate housing requirements to suit the bearing directly into the shell, maximising bearing sizes resulting in a custom heavy duty roller.
Premium quality rubber for maximum service life.
PROK’s rubber disk compounds are engineered to provide optimal performance in abrasion and impact resistance to maximise service life.
Fire resistant and anti-static, options available
Fire Resistant and Anti Static Rubber impact disks are also available to suit underground coal mines, grain terminals and sugar mills. FRAS Impact rollers meet the Mines Department MDG 3006 MTR8 and the Mine Safety & Health Administration MHSA#1C-199 (USA) approvals.
