CAT 466-2898 Bearing

CAT 466-2898 is a high-carbon alloy steel radial ball bearing designed by Caterpillar for the rear axle assembly of telescopic forklifts. It is compatible with models such as TH414C/TH514C/TH417C and is used to support rotating parts, transmit radial loads, withstand heavy loads and vibration conditions, and ensure stable operation of the transmission system. The following is structured technical and application information:

Core Technical Parameters

Item Details
Basic Attributes

Compatible Models and Applications
Compatible with Cat TH414C, TH514C, TH417C Telescopic boom forklift, used for rear axle hub/differential end support. Accessories include bearing housings, dust covers, and lock nuts. Suitable for speeds ≤3000 r/min, rated radial load ≥12 kN, rated axial load ≥3.5 kN.

Performance Parameters: Rated dynamic load 15.2 kN, rated static load 8.6 kN, limiting speed (grease lubrication) 6000 r/min, fatigue life ≥10000 hours, coefficient of friction ≤0.0015, waterproof and dustproof rating IP54.

Structural and Performance Advantages:
Wear-resistant and fatigue-resistant: High-carbon chromium bearing steel, quenched and tempered, achieves a balance of hardness and toughness, suitable for frequent start-stop and heavy-load conditions of forklifts, reducing the risk of wear and fatigue failure.

Precise positioning: Deep groove ball bearings can simultaneously withstand radial and a small amount of axial loads. Double-sided dust covers effectively block dust and moisture, ensuring bearing cleanliness and lubrication.

Low Friction, High Efficiency: The reinforced nylon cage guides the steel balls to rotate smoothly, reducing frictional loss and improving transmission efficiency, making it suitable for low-to-medium speed, high-load rear axle applications.

Easy Assembly: Standard dimensions and C3 clearance design fit original bearing housings, requiring no additional adjustments during installation. Secure with the lock nut, improving maintenance efficiency.

Installation and Maintenance Points: Before installation, clean the bearing, journal, and bearing housing, checking for scratches/rust. Use cold fitting or press fitting (pressure ≤ 5 kN, applied to the inner ring), and do not strike the outer ring. Tighten the lock nut to the specified torque (35-40 N・m) to prevent bearing movement.

After installation, check the radial clearance to be 0.015-0.030 mm, axial movement ≤ 0.05 mm, and rotation without jamming. Run for 30 minutes; bearing temperature ≤ 75℃, with no abnormal noise or overheating.

Maintenance: Check the bearing condition every 500 hours, and add grease every 1000 hours (the amount should be 1/3 of the bearing cavity volume). Replace the bearing immediately if any abnormal noise, abnormal temperature rise, or excessive clearance is found.
