Core Parameters and Information

Item Details
Part Model: CAT 299-0600 Bearing

Part Type: Single-row radial ball bearing with dust cover, used for radial support in slewing/drive components

Material: Bearing steel (GCr15), inner/outer ring integrally hardened (HRC 60–64), cage is stamped steel, seal is nitrile rubber

Key Dimensions: Inner diameter approx. 30.00 mm (1.181 in), outer diameter approx. 62.00 mm (2.441 in), width approx. 16.00 mm (0.630 in), with contact-type dust covers on both sides

Structural Features Equipped with a dust cover for sealing, preventing dust and moisture intrusion; suitable for low to medium speed and medium load conditions.

Compatible Structure: Matches shafts and bearing housings, used for radial support parts such as slewing platforms, drive shafts, and gearbox output shafts.

Applicable Working Conditions: Low to medium speed and medium load, suitable for dusty and humid outdoor operating environments.

Compatible Models:
CAT 305.5E2/306E2 Mini Excavators (slewing platform, drive shaft support parts)
CAT 906M/907M Wheel Loaders (gearbox output shaft, boom/stick hinge support parts)
CAT 279D/289D Compact Tracked Loaders (drive shaft, connecting rod support parts)
CAT 420F/430F Excavator Loaders (slewing mechanism, working device drive parts)

Installation and Fitting Points: Interference fit with shafts (0–0.012 mm); clearance fit with bearing housings (0.010–0.025 mm clearance). (mm), ensuring smooth and unobstructed rotation.

Use a dedicated press-fit tool for cold pressing assembly; do not directly strike the inner and outer rings of the bearing.

Before installation, clean the journal and bearing housing bore to remove burrs, rust, and impurities, and check the integrity of the seals.

Axially position the bearing using the end cover/retaining ring to prevent movement; after installation, check for smooth rotation, no abnormal noise, and no axial movement.

Pre-lubricate the bearing; check the lubrication status and add grease every 800 working hours according to the machine manual.
