CAT 584-5795 BEARING-SLV-GD

CAT 584-5795 is a Caterpillar original equipment manufacturer (OEM) standard load straight sleeve bearing (shoulder sleeve), suitable for pin hinges and light to medium load rotating parts of small and medium-sized excavators and loaders, balancing wear resistance and cost. The following are the key information.

Core Technical Parameters

Item Details

Load Capacity Radial rated load: 65 kN; Static allowable load: 90 kN; Coefficient of friction: 0.09-0.13 (grease lubrication)

Structure and Core Functions
**Suitable for Conventional Loads:** 4140 steel base with surface hardening, suitable for medium-load articulation points such as booms and sticks under non-extreme impacts, balancing wear resistance and economy.

Highly Efficient Lubrication: Internal axial lubrication groove design ensures uniform grease distribution, reducing dry friction, suitable for intermittent oscillating conditions.

Easy Installation: Thin-walled straight cylindrical structure allows for cold press-fitting without complex tooling, suitable for batch maintenance scenarios.

Controllable Clearance: Precise tolerance control and reasonable clearance ensure flexible rotation and reduce the risk of abnormal wear on pins and mounting holes.

Compatible Models and Application Scenarios
**Compatible Equipment:** CAT 305.5E2, 306E2 mini excavators, 906M, 907M loaders, 420F backhoe loaders, etc.

Core Applications: Used for boom pin bushings, stick cylinder clevis bushings, connecting rod hinge points, etc., providing radial support, suitable for light to medium loads, low to medium speed swinging or rotating conditions.

Installation and Maintenance Points

Installation: Clean the mounting holes and bearing surfaces, ensuring they are free of burrs and scratches; apply a pressing force of 6-10 kN, using a dedicated press head to press evenly, avoiding striking the end face to prevent damage to the hardened layer.

After installation, coaxiality should be ≤ 0.05 mm, and the clearance should be controlled within 0.03-0.06 mm, ensuring smooth rotation.

Maintenance: Grease lubrication: Add NLGI Grade 2 lithium-based grease every 400-600 hours, until overflowing; oil lubrication uses CAT HYDO 10 hydraulic oil.

Regularly check the clearance. If the clearance exceeds 0.15 mm or abnormal noise occurs, replace the component promptly to prevent accelerated wear of related parts.
