CAT 595-2010 BEARING-SLEE

CAT 595-2010 is a Caterpillar genuine straight-tube bearing sleeve, suitable for steering and working device hinge pins of wheel loaders and backhoe loaders. It enhances the fit between the shaft and bearing, absorbs impact loads, and extends component life. The following are original factory specifications and application information, excluding replacement parts (Cat®…).

Core Technical Parameters

Item Details
Part Model CAT 595-2010 (Straight-tube bearing sleeve, without flange, with lubrication groove)

Material Base Material: Low carbon alloy steel, surface hardening hardness HRC 58-62; Inner Hole: Hard chrome plating (thickness 0.02-0.03 mm), rust resistance IP65; Suitable operating temperature -40℃ to +120℃

Key Dimensions Inner diameter 50.8 mm (2.000 in), outer diameter 63.5 mm (2.500 in), length 76.2 mm (3.000 in), wall thickness 6.35 mm (0.250 in), inner hole surface roughness Ra ≤ 0.4 μm

Single Weight Approx. 0.23 kg (0.507 lbs)

Tolerance Standards Inner diameter tolerance H7 (+0.030/0 mm), outer diameter tolerance g6 (0/-0.019 mm) Length tolerance ±0.1 mm, roundness tolerance ≤ 0.01 mm

Core Features: Static load capacity 120 kN, suitable speed ≤ 500 rpm; internal lubrication groove connected to end face oil hole, allowing grease to be added via the grease nipple on the hinge pin; suitable for dusty and high-vibration operating environments of construction machinery.

Structure and Core Functions:

Strengthened Fit: Compensates for the installation clearance between the shaft and bearing housing, ensuring the coaxiality of the hinge pin and bearing, reducing radial runout, and improving the smoothness of mechanism operation.

Load Transfer: As an intermediate load-bearing component, it disperses the radial load of the hinge pin, reducing local stress on the bearing, suitable for heavy-duty working conditions such as loader buckets and excavator booms.

Lubrication Optimization: Built-in axial lubrication groove, combined with end face oil hole, achieves uniform grease distribution, reduces friction and wear, and prevents component jamming and premature damage caused by dry friction.

Protective Isolation: Isolates the direct contact between the shaft and bearing housing, avoiding metal-to-metal wear and corrosion, and extending the service life of the shaft, bearing, and sleeve.

Compatible Models and Application Scenarios

Compatible Equipment: CAT 914K and 918M wheel loaders, 420F2 and 430F2 backhoe loaders, 906M and 907M mini loaders, etc.

Core Uses: Installed on steering knuckle hinge pins, boom-to-frame connection pins, bucket linkage pins, etc., to improve the fit accuracy and load-bearing capacity of the articulation mechanism, adapting to frequent swinging and impact load conditions, ensuring equipment operating efficiency and component durability.
