CAT 584-7384 BEARING-SLV-GD

CAT 584-7384 (5847384) YM is a Caterpillar original general-purpose (GD) straight sleeve bearing, suitable for the hinged parts of the chassis and working devices of tracked bulldozers, loaders, etc. The following is purely precise information (no additional description):

Core Parameters and Information

Item Details
Part Model: CAT 584-7384 YM Sleeve Bearing

Part Type: Straight sleeve bearing without flange, used for sliding friction between the pin and the support, bearing radial loads, suitable for medium and low speed oscillation/rotation

Material: Low carbon alloy steel (C 0.15-0.25%, Cr 0.8-1.2%), surface carburizing and quenching + low-temperature tempering, surface hardness HRC 58-62, core hardness HRC 28-35, wear-resistant and impact-resistant

Key Dimensions: Inner diameter 45.00 mm (1.7717 in), outer diameter 50.00 mm 1.9685 in diameter, 45.00 mm (1.7717 in) overall length, 2.5 mm wall thickness, no oil groove/hole

Structural Features: Straight cylindrical type, no flange, cylindrical surface fit, interference fit with pin, clearance fit with mounting hole, suitable for unlubricated or periodically lubricated conditions

Compatible Structures: Tracked bulldozer balance beam pin bearing, loader boom and stick hinge bearing, excavator stick and bucket pin bearing, grader blade swing arm bearing

Applicable Working Conditions: Suitable for swing/rotation scenarios at low to medium speeds (≤500 rpm) and medium to light loads (radial load ≤30 kN) from -30℃ to 100℃

Compatible Models and Assemblies: Tracked bulldozers: CAT D6R, D6T, D6H, D6GC series (balance beam, push rod, connecting rod pin bearings)
Loaders: CAT 950H, 962G, 980K Series (Boom, Rocker Arm, Tie Rod Hinge Bearings)

Excavators: CAT 320D, 330D Series (Stick, Bucket Pin Bearings)

Graders: CAT 140H, 160M Series (Shovel Arm, Drawbar Hinge Bearings)

Installation and Fitting Points

Pin diameter: 44.98-45.00 mm, interference fit with the bearing inner diameter (interference 0.01-0.02 mm), no relative rotation.

Mounting hole diameter: 50.02-50.05 mm, clearance fit with the bearing outer diameter (clearance 0.02-0.05 mm), easy installation and adjustment.

Use cold pressing method for installation. Apply pressure evenly with a special press. Direct hammering is prohibited to prevent bearing deformation and surface damage.

Before installation, clean the pin and mounting hole, ensuring no burrs, oil stains, or rust. Inspect the bearing inner and outer diameters for scratches and pits.

After installation, the bearing end face fits snugly against the support plane, swinging/rotating without jamming or abnormal noise. Regularly add lithium-based grease (every 500 working hours).
