CAT 382-8046 BEARING-SLV-GD

CAT 382-8046 is a Caterpillar genuine YM wear-resistant pad (fitted for excavator boom/stick hinge joints and loader bucket pin bushing end faces, used for limiting, wear resistance, and anti-loosening, protecting pins and bushings). The following is pure original data and does not include replacement parts information.

Core Technical Parameters (Raw Data)

Item Details
Basic Attributes
Model 382-8046, Type YM Flat Wear-Resistant Pad (No Positioning Groove), Material 42CrMo Alloy Steel (Quenched + Tempered), Surface Carburized Hardened, Single Weight 0.82 kg, Working Temperature -40℃ to +120℃, Compatible with Lithium-Based Grease (NLGI 2), Rated Compressive Strength ≥1200 MPa, Rated Shear Strength ≥850 MPa, Fatigue Life ≥8500 Hours, Coefficient of Friction μ≤0.006, Compatible Pin Hardness HRC 58-62, Compatible with Mineral Oil/Synthetic Hydraulic Oil Environment

Key Dimensions
Length 120 mm (4.724 in), Width 80 mm (3.150 in), Thickness 12 mm (0.472 in), Mounting Hole Diameter 18 mm (0.709 in), Hole Spacing (Center Distance) 100 mm × 60 mm, Chamfer r0.8 mm, flatness tolerance ≤0.05 mm, thickness tolerance ±0.08 mm, surface roughness Ra 0.2 μm, hardness HRC 58-62, hardened layer depth 0.8-1.2 mm
Compatible Models and Parts: Compatible with the end face of the hinge point bushing on the boom of Cat 320D2 and 323D2 excavators, and the side pad of the bucket pin shaft on 950M loaders. Two pieces are provided for each part to limit the axial displacement of the bushing, reduce end face wear, and improve the stability of the hinged parts.
Performance Parameters: Impact load capacity ≥180 kN, wear resistance ≥6000 hours (normal lubrication), bushing clearance 0.02-0.05 mm, mounting bolt specification M16×80 (8.8 grade), preload torque 180 N・m
Structural and Performance Advantages: Flat grooveless structure: adapts to standard bushing end face installation, simple structure, convenient installation, no additional positioning structure, adaptable to various hinged parts, and highly versatile. 42CrMo alloy steel material: Quenched and carburized, it boasts high surface hardness, excellent core toughness, and superior impact and wear resistance, making it suitable for harsh working conditions in engineering machinery.

Precise dimensional tolerances: Strict flatness and thickness tolerances ensure a tight fit between the installed rear face and the substrate, reducing impact and wear caused by gaps and extending component life.

Installation and maintenance points (raw data)

Installation: Clean the pad and mounting surface. Tighten with 8.8 grade M16 bolts, with a preload torque of 180 N·m. After installation, the surface runout should be ≤0.05 mm, and the surface roughness Ra ≤0.3 μm. Welding is prohibited to prevent material performance degradation.

Maintenance: Check bolt tightness every 500 hours and pad wear every 1500 hours. Normal use is possible when the thickness wear is ≤1.0 mm; replace the pad if the wear exceeds this limit.

Troubleshooting: For abnormal noises from the end face, check the fit and lubrication of the pad; for abnormal wear, check for gaps and loose bolts, and adjust or replace the pad in a timely manner.
