Roller Bearings with Hex Shaft
End caps built around a hex shaft rather than a spring-loaded round shaft. The hex locates positively in a matching slot in the conveyor frame, so the shaft cannot rotate and the roller cannot creep sideways.
Roller bearings with Hex Shaft models we manufacture
The problem this group solves
Spring-loaded round shafts are quick to fit but can work out of the frame slot under vibration or side impact; a hex shaft removes that failure mode.
How to choose
Measure across the flats of the existing shaft and match the frame slot; hex and round shafts are not interchangeable without changing the frame.
Typical applications
- Vibrating and mobile conveyor sections
- Frames already punched for hex shafts
- Applications where the shaft must not rotate
- Driven roller groups needing positive location

Frequently Asked Questions
Which hex sizes are available?

Can I fit a hex-shaft roller into a round slot frame?
Not directly. The frame slot has to match the shaft form.
