Product Description (longer text for listing)

The NTN 32912XA is a single-row tapered roller bearing. This bearing type uses tapered rollers running between conical raceways on the inner and outer rings. Thanks to this design, tapered roller bearings can support combined loads, handling both high radial loads and axial loads in one direction. The larger the contact angle, the higher the axial load capacity.

The bearing is supplied as a combination of cone and cup:

• The cone assembly consists of the inner ring, cage, and roller set.
• The cup is the outer ring.

Single-row tapered roller bearings like the 32912XA NTN have an open design. Due to their internal geometry, they are usually mounted in pairs, in mirror-image arrangement or in X, O, or tandem configurations, depending on the required load direction, stiffness, and alignment.
