The CAT 116-3501 is a Caterpillar original shaft locating/guide sleeve, commonly used in engine valve mechanisms, hydraulic cylinders, or transmission components. Its core function is to locate, guide, and protect shaft parts, reducing wear and impact. It is compatible with many CAT heavy-duty equipment and engines. The following is key information.
Core Technical Parameters
Item Details
Part Model: CAT 116-3501 (Shaft Sleeve, Single Piece)
Material: 4140 alloy steel, quenched and tempered heat treatment, tensile strength ≥950MPa, hardness HRC 28-32, combining strength and toughness, surface nitriding treatment improves wear resistance
Key Dimensions: Inner diameter approx. 45mm, outer diameter approx. 60mm, total length approx. 80mm, chamfered ends 5×45°, compatible with standard shaft diameters and mounting holes, mounting clearance 0.02-0.05mm
Single Weight: Approx. 0.85kg (1.87 lbs)
Core Features: High-precision inner and outer diameters, coaxiality ≤0.01mm; nitrided surface hardness HV 650-750, wear-resistant and corrosion-resistant; suitable for reciprocating or rotary motion under high temperature and high pressure conditions
Suitable Operating Conditions: Operating temperature -40℃ to + 150℃, suitable for engine valve guides, hydraulic cylinder piston guides, transmission gear shaft positioning, etc., resistant to alternating loads and impacts.
Structure and Core Functions
High-Precision Guiding Structure: Precision fit between the inner hole and shaft, and the outer circle and mounting hole, providing stable guidance for shaft parts, preventing radial offset, reducing friction and wear between parts, and ensuring motion accuracy.
Reinforced Material and Surface Treatment: 4140 alloy steel, after tempering, has high internal toughness; the nitrided surface forms a wear-resistant layer, preventing rapid wear of the sleeve during high-frequency movement and extending its service life.
Positioning and Buffering Function: Axially positions shaft parts, limiting their displacement; when used with seals or bushings, it can absorb vibration and impact, reduce equipment operating noise, and improve component operating stability.
Protection and Isolation Function: Isolates the shaft from the housing/cylinder, preventing wear and scratches caused by direct metal-to-metal contact, while preventing impurities from entering the mating surfaces, ensuring component cleanliness and operating efficiency.
Compatible Models and Application Scenarios
Compatible Equipment: CAT C15/C18 engines, 330/345 series excavators, 966/972 series loaders, etc.
Installation Locations: Engine valve guides, hydraulic cylinder piston rod guide sleeves, gear shaft positioning points in transmission systems, steering mechanism pin guide parts, etc.
Core Purpose: Provides precise guidance and positioning for shaft components, reduces wear, absorbs shock, ensures stable operation of the engine, hydraulic and transmission systems, and is suitable for heavy-duty and high-frequency operating conditions.
