The dynamic load rating of 9.95 kN characterises this bearing. The static load rating is 4.75 kN. The deep groove ball bearing is the most widely built rolling bearing type, and the reason is how little it asks: it carries radial load, supports moderate axial load in both directions, and demands little of the surrounding design. 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 non-contact seal works with a narrow gap rather than bearing against a face: it protects better than a shield and costs less frictional torque than a contact seal. Rings and rolling elements are made of through-hardened standard bearing steel.
The normal radial clearance recorded corresponds to the standard class and suits ordinary fits and temperature conditions. Low-friction seals on both sides — Dimensional/form-fit equivalent — verify suffix-level details for critical applications. Matching suffixes are also listed by NTN (LLH).

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.
