Tapered Roller Bearing with Adapter Sleeve – Type KU

Tapered roller insert for high combined radial and axial loads

Tapered roller bearing insert with adapter-sleeve mounting. Geared for high combined radial and axial loads where ball or spherical roller solutions reach their economical limits in the same envelope. The adapter sleeve enables controlled mounting and removal without press fits on the shaft journal - critical for service-intensive equipment.

Selected when axial thrust is a defining constraint, or when the duty cycle combines heavy radial loads with significant thrust components. (Internal code: Type KU.)

Mounting and selection guidance

Choose this insert when:

• Heavy combined radial and axial loads in the same shaft position
• Service-intensive equipment requiring removable mounting (no press fit on journal)
• Process pumps, mixers, gearbox shafts, and heavy conveyor head pulleys
• Larger shaft sizes where adapter-sleeve mounting is the practical method

Consider an alternative when: axial clearance must be set or preloaded per procedure (compare the adjustable variant), or when self-alignment under shaft deflection is the priority over thrust capacity (look at the spherical roller variants).

Mounting: adapter-sleeve assembly is sensitive to correct seating and nut torque. Follow the mounting guide for the size and confirm the sleeve travels evenly during drive-up - improper seating reduces load capacity and generates heat.

Load and speed per SKU

The table lists each active catalogue SKU for this insert type with radial load, axial load, and maximum speed as defined for that exact unit (housing variant, seals, and size included). Use the search box to filter by SKU fragment, or open the product page for the full datasheet. You can also browse all options in the product configurator.

Mounting warning Do not under-tighten adapter hardware - undersized seating reduces load capacity and accelerates wear. Consult the installation manual for the locking method supplied with the selected size.
