CAT 607-3567 (6073567) is a Caterpillar original equipment manufacturer (OEM) lift cylinder bearing, suitable for the hinge joint between the lifting arm and cylinder of loaders and excavators. The following is precise information (without additional description):

Core Parameters and Information

Item Details
Part Model: CAT 607-3567 Lift Cylinder Bearing

Part Type: Self-lubricating radial spherical bearing, used at the hinge joint between the lifting arm and cylinder, bearing radial + bidirectional axial combined loads, suitable for oscillating motion

Material: Outer ring: 50Mn alloy structural steel, hardened HRC58-62; Inner ring: 42CrMo, tempered HRC28-32; Liner: PTFE fabric composite layer, self-lubricating oil-free design

Key Dimensions: Inner diameter 44.50 mm, outer diameter 69.85 mm, width 25.40 mm, spherical radius 22.25 mm, clearance 0.05-0.10 mm

Structural Features: Spherical outer ring, cylindrical inner ring, with sealing ring to prevent mud and water, PTFE liner for dry operation, suitable for ±15° swing angle

Suitable Structures: Loader boom cylinder upper hinge point, excavator boom cylinder lower hinge point, grader blade cylinder hinge joint

Applicable Working Conditions: Suitable for construction machinery hinge joints operating at -30℃ to 140℃, medium to heavy load (radial load ≤80 kN), and low swing frequency (≤10 times/minute)

Suitable Models:
CAT 938M/950GC Loader (boom cylinder upper hinge point, boom cylinder hinge bearing)
CAT 320GC/323GC Excavator (stick cylinder upper hinge point, bucket cylinder hinge bearing)
CAT 140M/160M Grader (blade lifting cylinder hinge bearing, ripper cylinder joint bearing)

CAT 420F2/430F2 Wheel Excavator (Boom Cylinder Lower Hinge Point, Slewing Platform Cylinder Hinge Bearing)

Installation and Fitting Points:

Mounting hole diameter: 69.85-69.95 mm; Hinge shaft diameter: 44.45-44.50 mm; Bearing and hole/shaft should have a transition fit, with no looseness.

Use a hydraulic press to smoothly press the bearing into the mounting hole. Do not hammer, as this may deform the bearing or damage the liner.

Before installation, clean the mounting hole and hinge shaft, ensuring they are free of burrs and oil stains. Check that the bearing seals are intact and the liner is undamaged.

After installation, the bearing end face should be flush with the mounting surface. Axial movement should be ≤0.05 mm, with no jamming during oscillation, and no leakage from the seal.

No additional lubrication is required; the PTFE liner is self-lubricating. Check the seal every 2000 hours to prevent dust ingress.
