Deep Groove Ball Bearing (ZrO2)

The full ceramic ball bearings listed below are supplied with rings and
balls made from zirconium dioxide (ZrO2). These zirconia bearings are
available as full complement (no cage) or with cages made from PTFE,
PEEK or 316 stainless steel.

These are non magnetic, non-conductive and highly corrosion resistant
to most chemicals although ZrO2 bearings are not recommended for
prolonged contact with steam. Full complement bearings or those with a
316 stainless cage can be used up to 400°C while bearings with a PEEK or
PTFE cage can cope with temperatures of up to 250°C. For temperatures
below -70°C, PTFE or 316 stainless steel cages are preferred. Standard
radial clearance for full ceramic bearings is C0 but other clearances
can be supplied to order.

Our zirconia ceramic bearings are available from stock in the China
open or with PTFE/PEEK seals. Some sizes may also be available flanged.

ZrO2 ceramic bearings are generally used for their extreme temperature
capabilities, excellent corrosion resistance or non-magnetic properties.
Other sizes can be supplied on request.
