Core Technical Parameters

Item Details
Part Model: CAT 533-8162 (Straight Sleeve)

Product Type: Straight sleeve for use with pins in engineering machinery, used in joints, connecting rods, or frame connections to bear radial loads, provide positioning, and reduce wear between the pin and mounting hole.

Material: 4140 alloy structural steel, heat-treated (hardness HRC 28–32), surface nitrided, nitriding layer depth 0.3–0.5 mm, excellent wear resistance and fatigue resistance.

Key Dimensions: Inner diameter 65 mm (2.56 in), outer diameter 80 mm (3.15 in), total length 100 mm (3.94 in), wall thickness 7.5 mm, compatible with standard pins and mounting holes.

Lubrication Structure: No built-in lubrication groove; requires a pin lubrication system and lubrication via external grease injection. Compatible with lithium-based grease. Operating temperature: -30℃ ~ +120℃.

Weight: Approx. 2.85 kg (6.28 lbs)

Installation Tolerances Inner diameter tolerance H7, outer diameter tolerance g6, length tolerance ±0.1 mm, ensuring precise fit with pins and mounting holes.

Suitable media: Hydraulic oil for construction machinery, gear oil, etc., oil-resistant and anti-aging, suitable for dusty and humid outdoor conditions.

Structure and core characteristics:
High-strength material: 4140 alloy structural steel, tempered and nitrided, combining high strength and high wear resistance, capable of withstanding high-frequency vibration and heavy-load conditions in construction machinery, extending service life.

Precise dimensional control: Strict tolerance standards ensure reasonable clearance between the sleeve and pin/mounting hole, reducing impact and wear, and preventing abnormal noise or component damage caused by looseness.

Wear-resistant surface treatment: Nitriding treatment forms a hard, wear-resistant layer, reducing the coefficient of friction and wear between the pin and sleeve, suitable for long-term reciprocating motion conditions.

Straight cylinder structure adaptability: Flangeless design, suitable for connection parts requiring axial adjustment, easy installation, quick replacement, improving maintenance efficiency.

Compatible Models and Application Scenarios

Compatible Equipment: CS-533, CS-538 series vibratory rollers, and steering linkages, balance beams, and other components of some small loaders.

Core Purpose: Installed between the pin and the mounting hole, it supports the pin and transmits load, reducing direct contact wear between the pin and the mounting hole. It also positions the pin, ensuring the stability of the connection. Suitable for high-frequency vibration and heavy-load components such as vibratory wheel connections and frame joints on road rollers.
