High Temperature Deep Groove Ball Bearings



High temperture deep groove ball bearing

KX Series Deep groove high temperature ball bearings for service up to 500 °F.

Deigned for reliable long term use, they are manufactured with increased internal clearance and heat stabilized steel. This produces consistent thermal expansion cycles and room for internal raceway clearance reduction from differences in temperature found in machinery that could damage a bearing.

The bearings are factory lubricated with our high temperature non-hardening grease that is thermally stable, protects the bearing from corrosion, and maintains a useful viscosity up to 550 °F.

Standard Duty: We stock a wide range of standard deep groove ball bearings, most items are listed on our on-line ball bearing catalog. If you can't find what you need, contact us for help and to request a quote!

Corrosive Service: Ball bearings that have been through our anti-corrosion treatment will outperform standard 440C stainless steel bearings. This process can be applied to any deep groove ball bearing on request. We also offer standard 440C deep groove ball bearings.


Non-Stock:HTB will produce high temperature versions of any standard ISO deep groove ball bearing on a work order basis, contact us to request a quote!
