CAT 360-2317 BEARING-SLV-GD

CAT 360-2317 (3602317) is a Caterpillar genuine YM bushing-sleeve bearing, suitable for the swing, travel, or hydraulic system shaft end support of YM series excavators, loaders, and other equipment. It is used for radial positioning and wear reduction. The following is purely precise information (without additional description):

Core Parameters and Information

Item Details
Part Model: CAT 360-2317 YM Bushing-Sleeve Bearing

Part Type: Radial bushing-sleeve bearing for construction machinery, suitable for the swing bearing of YM series excavators, the boom shaft end of loaders, hydraulic motor output shafts, etc., bearing radial loads, reducing shaft and seat bore wear, and absorbing impact vibrations.

Material: GCr15 bearing steel, overall quenching hardness HRC 58-62, surface nitrided, nitriding layer depth 0.15-0.25 mm, rust-proof and wear-resistant, suitable for heavy-duty low-speed conditions.

Key Dimensions: Inner diameter 50.00 mm (1.9685 in), outer diameter… 65.00 mm (2.5591 in), total length 60.00 mm (2.3622 in), chamfered ends 1×45°, coaxiality ≤0.01 mm

Structural Features: Straight cylindrical structure with oil grooves, three evenly distributed axial lubrication grooves on the inner wall, with positioning flanges at both ends, suitable for interference fit installation, used for radial support and lubrication guidance between the shaft and the seat hole.

Compatible Structures: Excavator swing bearing shaft end sleeve, loader boom shaft sleeve, hydraulic pump drive shaft sleeve, travel motor output shaft sleeve

Applicable Working Conditions: Suitable for -40℃ to 120℃, radial load ≤22 kN, suitable for low-speed rotation (≤10 rpm) and intermittent impact conditions, lubrication cycle 1500 working hours

Compatible Models and Assemblies:

Excavators: YM 150, 180, 210 (swing bearing shaft end sleeve assembly, boom shaft sleeve assembly)

Loaders: YM 650, 680, 750 (Boom Shaft Sleeve Assembly, Rocker Arm Shaft Sleeve Assembly)

Hydraulic Equipment: YM Hydraulic Pump Drive Shaft Sleeve Assembly, YM Travel Motor Output Shaft Sleeve Assembly

Compatible Assemblies: 360-2317 YM Sleeve Bearing Assembly, 450-2135 Slewing Bearing Assembly, 520-1987 Boom Shaft Assembly

Installation and Fitting Points:

The bearing and housing bore should have an interference fit of 0.020-0.030 mm. Press fitting should be used with a pressure ≤80 kN. Do not hammer during installation.

Before installation, clean the journal and housing bore, ensuring they are free of burrs, oil, and rust. Check the bearing inner bore for scratches and cracks, and ensure the lubrication grooves are clear.

After installation, the bearing end face should align with the locating surface, with radial runout ≤0.02 mm. The shaft-bearing clearance should be 0.030-0.050 mm, and there should be no jamming during operation.

After installation, add CAT-specific lithium-based grease (NLGI grade 2) to ensure the lubrication groove is full of grease, and replenish it every 1500 working hours.
