ZEN S2200-2RS Pendelkugellager (10x30x14)

As a self-aligning ball bearing, this bearing compensates for misalignment and shaft deflection. The principal dimensions are 10x30x14 mm at a weight of 0.035 kg; the further technical details are listed in the specification table. This variant features a contact seal and stainless steel. The compliance of this type has a price: the spherical outer raceway conforms only shallowly, which lowers load ratings against closely conforming grooves.

Two rows of balls run on a common spherical outer raceway whose centre of curvature lies on the bearing axis. The inner ring assembly therefore remains free to swivel inside the outer ring: misalignment between positions and the deflection of long shafts are absorbed without edge loading the raceways. The price of that compliance is the shallow conformity of the spherical outer raceway — the contact area is small, load ratings are correspondingly lower than for closely conforming grooves, and only modest axial load is permissible.

The type belongs where alignment error is certain to occur and radial load stays moderate, such as long shafts in pedestal housings and in conveying equipment. 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. Contact seals on both sides (rubber lip seal) — Dimensional/form-fit equivalent — verify suffix-level details for critical applications. Matching suffixes are also listed by SKF (2RSH, 2RS1), FAG (2RSR), NSK (DDU), NTN (LLU) and NACHI (2NSE).
