CAT 087-0987 BEARING

CAT 087-0987 (0870987) is a Caterpillar genuine construction machinery needle roller bearing (with cage), suitable for 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used at the hinge points of the working device and is paired with the 087-0328 bushing, 087-0385 elastic retaining ring, and 086-9971 dust cover. It bears radial loads, reduces friction and wear at the hinge points, and ensures stable operation.

Core Parameters and Information

Item Details
Part Model: CAT 087-0987 (0870987) Needle Roller Bearing (with Cage)

Type: Needle Roller Bearing for Construction Machinery Articulation Points (with Cage)

Material: Bearing steel (GCr15), cage is reinforced nylon

Key Dimensions: Inner diameter 55mm, outer diameter 60mm, length 30mm, needle roller diameter 3mm, quantity 16 pieces

Compatible Models: CAT 259D3/279D3 skid steer loaders, 906H/907H mini excavators

Matching Relationship: Compatible with 087-0328 bushing, 087-0385 elastic retaining ring, 086-9971 dust cover, used for articulation point assemblies

Suitable Applications: Suitable for articulation points of skid steer loaders, mini excavators, boom and frame, connecting rod and boom, etc., suitable for frequent load changes. Application Scenarios: Suitable for frequent load-changing operations such as excavation and loading, bearing radial loads, reducing friction and wear at hinged joints, preventing component loosening, reducing the risk of failure, and improving operational safety and reliability.

Compatible Equipment: Uses with 087-0328 bushing, 087-0385 elastic retaining ring, and 086-9971 dust cover. The bearing bears radial loads, the bushing provides wear-resistant support, the elastic retaining ring provides axial positioning, and the dust cover protects against foreign object intrusion, ensuring stable component operation.

Installation and Maintenance Points:
Installation: Clean the mounting hole and shaft diameter, and inspect the bearing for any damage. Smoothly press the bearing into the mounting hole, and assemble it in sequence with the bushing, retaining ring, and dust cover, ensuring accurate axial positioning and no loosening.

Maintenance: Check the bearing for abnormal noise, wear, and jamming every 200 hours. Regularly add grease to maintain good lubrication and extend service life.

Replacement: Use special tools to remove the old bearing and check for damage to the mounting hole and shaft diameter; before installing the new bearing, check the dimensions to ensure that it fits tightly with the mounting hole and is not loose.
