The Cat 488-2150 is a Caterpillar articulated connection adapter, primarily used for the articulation points between the working device and the boom/stick of construction machinery. It enables precise connection, angle compensation, and load transfer between components, and is suitable for medium to high-intensity impact conditions. Below are the structured authoritative parameters and application points:
Core Parameters (Precise Version)
Item Details
Basic Attributes
Model 488-2150, Alloy steel articulated connection adapter/joint, used to connect the boom and stick, stick and bucket, connecting rod and rocker arm, etc., compatible with Cat 320GC/336GC/349GC excavators, 950M/966M loaders, D8T/D9T bulldozers, etc.
Compatible Models
320GC/336GC/349GC excavators (bucket connecting rod, stick cylinder lugs), 950M/966M/972M Loaders (boom and rocker arm, bucket pin bearings), D8T/D9T bulldozers (ripper cylinders, bulldozer blade hinges), 777F mining trucks (steering tie rod hinges, suspension system connections)
Material and Process: 40CrNiMoA alloy steel, quenched and tempered (HRC 30-35), surface hardened (raceway/mating surface HRC 50-55), blackened/galvanized for corrosion protection, tensile strength ≥1100MPa, yield strength ≥900MPa, pin hole roughness Ra 0.8μm, mating surface parallelism ≤0.02mm
Key Dimensions: Fitting pin diameter 50mm (1.969in)/60mm (2.362in), body length 120mm (4.724in), width 80mm (3.150in), height 65mm (2.559in), pin hole tolerance H7 (+0.030/-0), weight approx. 2.8kg, chamfer R2mm, installation clearance 0.02-0.05mm
Functional parameters: Axial load ≥200kN, Radial load ≥150kN, Operating temperature -40℃ to +120℃, compatible with mineral oil/lithium-based grease, can compensate for ±5° hinge angle deviation, includes pins (452-2185), bushings (442-2826), seals (5P-9210), grease nipples (1J-9834)
Matching components: Compatible pins 452-2185/452-2186, bushings 442-2826/442-2827, seals 5P-9210/379-2188, grease nipples 1J-9834, matching hinge pin hole precision. H7, during installation, ensure the coaxiality of the pin and bushing is ≤0.03mm. Functions, Installation, and Maintenance Points:
Core Functions: Enables flexible rotation and angle compensation at the hinge; transmits large loads (tension/compression/bending moment); protects the pin and bushing, reducing wear; adapts to dynamic load transmission under vibration and impact conditions, improving the reliability and service life of the connection.
Installation Points: Clean the pin hole and mating surfaces, removing burrs and oil; use a press to install the bushing, do not strike; ensure the adapter fits snugly with adjacent components, with an axial clearance ≤0.03mm; after installation, check that the hinge rotates freely without jamming or abnormal noise, and that radial runout is ≤0.03mm.
Maintenance points: Add lithium-based grease (10-9275) every 500 hours; check for wear of the pin and bushing and leakage of the seal every 2000 hours; disassemble and measure the wear of the pin hole every 6000 hours. Replace the adapter or bushing in time if the wear exceeds 0.1mm or the clearance exceeds 0.1mm.
