High Quality 32010 Tapered Roller Bearing for Excavator Final Drive

These are all single-row tapered roller bearings with different dimension series. 320 has the narrowest cross-section (light series), 322 is wider (medium), 323 is even wider (heavy), and 330 has a different width-to-diameter ratio. Choose based on available mounting space and load requirements.

P6X is a precision class specific to tapered roller bearings where dimensional tolerances meet ISO P6, but width tolerance is restricted (tighter than P6). It ensures consistent mounting height when used in pairs. It is not 'better' than P6 overall but offers tighter width control.

Adjust by setting the axial position of the cup relative to the cone. Common methods include tightening a locknut, using shims between the cup and housing shoulder, or using a spacer between paired bearings. Follow equipment manufacturer specifications to avoid overheating or noise.

A single bearing can carry radial and one-direction axial loads, but it generates internal axial force. It is usually used in pairs (DF, DB, or DT) to balance forces and handle loads from both directions, unless the application has constant one-direction axial load.

The cone is the inner ring assembly (inner ring, rollers, cage), while the cup is the outer ring. They are separable, allowing independent installation and easier mounting. You can order them as a complete set or separately for replacement.
