The dynamic load rating of 20.3 kN characterises this bearing. The static load rating is 11.2 kN. The limiting speed is 22000 rpm. This variant features increased radial clearance (C3). The shares deducted from the mounted clearance are manageable in this version: the interference fit and the heat flow supplied from outside, with no contribution from the sealing.
This combination stands out in that its two features act independently of one another, which simplifies the design work. The non-contact seal follows the contour of the inner ring with an elastomeric sealing body down to a narrow distance without touching it: no load-independent frictional torque arises, no heat source at the inner ring and no wearing contact point, so the permissible speed lies close to that of the open form and the barrier effect is retained over the operating period.
Increased clearance (C3) holds an allowance ready for the shares that consume the mounted clearance in service — the interference fit on the shaft and the temperature gradient between a warmer inner ring and an outer ring coupled through the housing. Because the sealing takes no part in that gradient, it originates here in the surroundings of the position: in a hot shaft, an adjacent process or the power lost in a fast-running drive.
That makes the estimate of the residual clearance in the warm running state more direct than in a version sealing by contact, where part of the warming arises inside the bearing itself. It remains to be observed that the gap does not permanently hold back liquid and very fine dust, and that the grease charge is enclosed and dimensioned for the service life, so its ageing at the elevated operating temperature can become the limiting quantity.
At low radial load the wider clearance has to be taken into account, because the load zone turns out narrower. Through-hardened standard bearing steel sets the frame for hardness and dimensional accuracy; the temperature limit of the sealing material is to be taken separately from the designation. Increased radial clearance C3 — Dimensional/form-fit equivalent — verify suffix-level details for critical applications. Matching suffixes are also listed by FAG (C3), NSK (C3), NTN (C3) and NACHI (C3).

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.
