Product Introduction: Sleeve Bearing (Bushing) 7D8889 for Caterpillar Equipment
Overview
The Sleeve Bearing (Bushing) 7D8889 is a precision-engineered component designed for Caterpillar equipment, specifically used to support rotational movement and reduce friction in linkage and hydraulic systems, such as steering or blade lift assemblies. This bearing, made from a polymer composite material, is critical for ensuring smooth operation and durability in demanding applications, primarily motor graders. Available as a new aftermarket or genuine OEM part, it provides a reliable and cost-effective solution for equipment maintenance.
Key Features
- Material: Constructed from high-grade polymer composite, designed to withstand high loads, resist wear, and perform reliably in harsh conditions. Offers enhanced corrosion resistance compared to steel and compatibility with lubrication for reduced friction.
- Design: Precision-machined cylindrical sleeve bearing, engineered to match OEM specifications for precise fitment and performance. Features no internal or external grooves or cross holes, ensuring a robust design optimized for high-stress environments like motor grader linkage systems.
- Compatibility: Compatible with Caterpillar equipment, specifically:
- Motor Graders: 120H, 120H ES, 120H NA, 120K, 120K 2, 120M, 120M 2, 12G, 12H, 12H ES, 12H NA, 12K, 12M, 12M 2, 12M 3, 12M 3 AWD, 130G, 135H, 135H NA, 140G, 140H, 140H ES, 140H NA, 140K, 140K 2, 140M, 140M 2, 140M 3, 140M 3 AWD, 143H, 160G, 160H, 160H ES, 160H NA, 160K, 160M, 160M 2, 160M 3, 160M 3 AWD, 163H, 163H NA. Typically used in steering or blade lift linkage assemblies to support rotating components. Exact model compatibility must be verified using the equipment’s serial number via CAT SIS, as compatibility cannot be confirmed without it per Caterpillar’s policy.
- Dimensions: Inside diameter: 76 mm; outside diameter: 89 mm; overall length: 83 mm.
- Quality Assurance: Manufactured to meet or exceed US OEM specifications, with quality control conducted in ISO 9001-certified facilities. Backed by a 1-year unlimited mileage warranty with no core charge.
