Product Description
- Part Type：Sleeve Bearing (Bushing)
- Description: Sleeve Bearing (Bushing) 4v1901 Suitable for Caterpillar
The 4V-1901 is a premium-quality aftermarket bronze sleeve bearing (plain bushing) manufactured as an exact, fully interchangeable replacement for the original Caterpillar® part number 4V1901 (4V-1901). This high-load bronze bushing is used in critical pivot points on loader lift arms and tilt linkage groups of large Caterpillar® wheel loaders, providing smooth, low-friction articulation while supporting massive bucket and material weights under extreme digging and racking forces.
Key Features & Benefits
- Manufactured from high-tin phosphor bronze alloy (SAE 660 / C93200 equivalent) for excellent load-carrying capacity and wear resistance
- Precision machined to exact OEM inner/outer diameters and length – true drop-in fit, no reaming or line-boring required
- Oil-impregnated or grooved versions available for superior lubrication retention and extended service life
- High compressive strength (> 450 MPa) and outstanding resistance to shock loading and deformation
- Superior anti-seizure properties compared to steel-backed or bi-metal bushings
- Significant cost savings while delivering performance equal to or better than genuine parts
Common Applications (Caterpillar® Compatibility)
- Large Wheel Loaders – lift arm and tilt linkage pivot points: – 980C, 980F, 980F Series II – 980G, 980G Series II – 980H (early models)
- Typically installed in the lift arm to frame (tower) and tilt cylinder / tilt lever connections
