106-7129 Straight Bronze Sleeve Bearing for Cat Motor Graders

The 106-7129 sleeve bearing is a straight bronze bushing designed as a replacement component for selected Cat motor grader assemblies. Its cylindrical bearing surface supports controlled rotational or sliding movement while helping maintain alignment between mating components under demanding working conditions.

The bearing has a 2.500-inch inside diameter, a 2.878-inch sleeve outside diameter and a 1.417-inch overall length. An internal groove supports lubricant distribution across the bearing surface, while the design contains no cross holes or external groove.

Depending on the machine model, serial number and parts arrangement, 106-7129 may be used in circle-drive or selected hydraulic cylinder assemblies. Always confirm the part number against the machine serial number and applicable parts catalog before purchase or installation.
