Lubricated with PTFE based on silicone free grease for temperatures up to 280°C
(with a drop point above 400°C)

The BHTS ZZ 280° ball bearings are designed on the dimensions of a standard bearing but
with treatments of stabilization, surface treatment, radial clearance, grease and special shield
that make them suitable for operation from –40° to +280°C. Their recommended range of
application is between 200° and 280°C where these bearings achieve their best performance.
Below 220°C there are the BHTS ZZ C4 220°-250° bearings available, which are cheaper and
also allow a much higher rotational speed. The BHTS ZZ 280° bearings are currently available
in approximately 400 different models, all of which are in stock and able to cover most of the
applications for bearings of high & extreme temperatures
