CAT 584-7175 BEARING-SLV-GD

CAT 584-7175 (5847175) YM is a Caterpillar heavy-duty straight-tube sleeve bearing, suitable for connecting rods, pivots, or counterweight beams of tracked bulldozers/loaders. It is used to support the rotation of the pin and bear radial heavy loads. It is a key wear-resistant component in the articulation and transmission parts of construction machinery. The YM mark represents a high-quality replacement part with performance close to the original Cat® standard. The following are the core information and key points:

Performance Parameters: Rated radial load 220kN, allowable linear speed ≤2m/s, operating temperature -30℃ to 120℃, wear life ≥8000 hours, suitable for mineral oil/synthetic hydraulic oil lubrication, can withstand short-term impact load ≤300kN.
Core Functions and Structure: Heavy-duty support: Bimetallic layer structure combined with solid lubrication provides stable radial support under high loads, suitable for frequent start-stop and impact conditions in construction machinery, dispersing contact stress between the pin and bearing housing, and avoiding localized wear.

Self-lubricating and wear-resistant: The alloy layer contains solid lubricating particles, which form a temporary lubricating film during oilless startup. Combined with lubrication grooves and oil injection holes, this ensures long-term adequate lubrication, reduces friction and wear, and extends the life of the pin and bearing housing.

Positioning and guiding: The straight cylindrical structure and precise dimensional tolerances ensure coaxiality between the pin and bearing housing, preventing jamming and abnormal wear caused by uneven loading, and ensuring flexible movement of the hinged parts.

High adaptability: YM quality parts have the same dimensions and installation interfaces as original equipment manufacturer (OEM) parts, allowing direct replacement of OEM sleeve bearings, meeting the cost-effective replacement needs of non-core operating conditions (Cat®…).
