Plastic Roller Bearings KTR
The KTR housing is the version with a deeper skirt and a defined shoulder that seats squarely in the tube, which keeps the bearing perpendicular and stops the slight wobble that makes cheap rollers noisy.
Plastic Roller Bearings KTR models we manufacture
The problem this group solves
An end cap that goes in slightly out of square puts a side load on the bearing from day one; the roller turns, but it rumbles and the bearing fails early.
How to choose
Order by tube inside diameter, bearing bore and shaft form; KTR and plain KT housings are not always interchangeable in the same tube.
Typical applications
- OEM gravity roller production
- Re-bearing existing roller stock
- Long dispatch runs where noise accumulates
- Light-load applications needing consistent roll resistance

Frequently Asked Questions
What is the difference between KT and KTR housings?
The KTR body has a different seating profile and skirt depth. Check the drawing against the tube you use rather than assuming a swap.
Can KTR caps be reused after removal?
Press fits lose grip once removed. For a rebuild, fit new caps.
