NKE 6202-2RS-NR Kugellager (15x35x11)

The dynamic load rating of 7.6 kN characterises this bearing. The static load rating is 3.7 kN. This variant features a contact seal. 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.

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).
