For this ZEN bearing, 12x28x8 mm and a weight of 0.022 kg apply; the specification table holds the further technical particulars. This variant features stainless steel. Point contact between ball and raceway keeps frictional torque low, which is why this type runs faster and cooler than any other rolling bearing. The deep, closely conforming raceway grooves in the inner and outer ring capture the balls positively, so the bearing takes radial load and moderate axial load in both directions without a second bearing position to oppose it.
Because the ball touches the raceway at a point, friction and heat stay low — the precondition for high speeds and for grease-for-life designs. The limits follow from that same geometry: the small contact area caps load capacity against a roller bearing of equal size, and the bearing tolerates misalignment within narrow limits only, since angular error transfers straight into the raceway grooves.
Seats in shaft and housing must therefore be aligned and geometrically accurate; where shaft deflection is expected, a self-aligning type belongs in that position. The contact seal bears against its counterface and closes the rolling chamber against dust, splash water and wash-out; in return it raises frictional torque and limits permissible speed.
The stainless steel version is intended for damp, wet or chemically loaded surroundings and for applications demanding freedom from rust; its load ratings sit somewhat below those of standard bearing steel. The normal radial clearance recorded corresponds to the standard class and suits ordinary fits and temperature conditions.

Same dimensions means the same bearing type and matching main dimensions (d × D × B). Sealing, cage, internal clearance and execution (e.g. material, precision, grease fill) are encoded in the suffix and may differ — please check before ordering. Equivalent additionally means the same sealing, internal clearance and tolerance class; the cage and other suffix features (e.g. lubrication groove) may differ.
