SWC High-temp Deep Groove Ball Bearings with the suffix HT3 are filled with a solid compound.
While running, small particals of the compound come lose and lubricate the bearing continously.
Bearings filled with HT3 are suitable for slow speeds and temperatures up to 300°C.
Depending on the application, these bearings allow maintenance-free operation up to 6 years.
All HT3 bearings are only available with shields on both sides (2ZR).
All High-temp Deep Groove Ball Bearings come with the following benefits:
Increased radial clearance (multiple of C5)
as compensation for temperature-induced deformations of the production goods
(rails, transport units)
for temperatures up to 250°C
Manganese phosphate coating (according to EN ISO 9717)
ensures increased protection against corrosion, good adhesion of lubricants
and better runability
Riveted sheet steel cage
provides high stability at low friction
