Core Parameters and Information

Item Details
Part Model: CAT 086-9824 (0869824) Needle Roller Bearing

Type: Inner Ringless Needle Roller Bearing for Engineering Machinery Articulation Points

Material: Bearing steel (GCr15), cage is made of high-quality engineering plastic

Key Dimensions: Inner diameter 55mm, outer diameter 60mm, width 25mm, needle roller diameter 3mm, quantity 15 pieces

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

Matching Relationship: Matched with 086-8559 elastic retaining ring and 085-8823/085-8827 bushings, 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, ensuring stable operation of hinge points, preventing component loosening and wear, reducing failure risks, and improving operational safety and reliability.

Compatible with: Uses with 086-8559 elastic retaining rings and 085-8823/085-8827 bushings. The elastic retaining ring provides axial positioning of the bearing, while the bushing provides wear-resistant support, ensuring stable component operation.

Installation and Maintenance Points:

Installation: Clean the mounting area and check the bushing dimensions; smoothly insert the bearing into the mounting position, ensuring a tight fit with the bushing; install the elastic retaining ring, ensuring axial positioning of the bearing without loosening.

Maintenance: Check the bearing’s operating condition every 200 hours for abnormal noises and overheating; regularly add grease to maintain good lubrication and extend service life.

Replacement: Remove the old bearing with a special tool and check the mounting position for damage; before installing the new bearing, verify the dimensions to ensure a tight fit with the mounting position without loosening.
