Plastic Roller Bearings
Plastic-housed gravity roller bearings with a steel bearing carried in a moulded end cap. They damp noise, cannot rust and are the standard fit on light and medium carton conveyors.
Plastic Roller Bearings models we manufacture
The problem this group solves
Steel end caps on a long dispatch run make a line loud enough to need ear protection; plastic housings cut that noise without changing the roller tube.
How to choose
Confirm tube inside diameter and bore, then check the ambient temperature — moulded housings should not be used at oven exits or near hot product.
Typical applications
- Carton and tote gravity runs
- Flow racks and pick-to-light shelving
- Humid areas where steel caps corrode
- Noise-sensitive packing halls

Re-bearing, re-wheeling and re-driving existing conveyor rather than replacing it.
Comparison GuidePlastic or Metal Roller End Caps
The end cap decides the noise, the roll resistance and the life of a gravity roller. Choosing between a moulded and a steel housing comes down to four questions.

Frequently Asked Questions
Do plastic bearings carry less load than metal?
Per roller, yes. On carton and tote work the load per roller is low enough that it rarely decides the choice.
Will plastic housings survive wash-down?
They do not corrode, but the bearing inside still needs protection from direct water jets.
