Description
OEM Part Number: 868.0799-00
This product is a genuine replacement cone crusher part, specifically the main shaft bearing for the Sandvik CH660 cone crusher. As a critical component in the crusher’s drive system, this bearing is essential for operational stability, load capacity, and service life. Our bearing is manufactured to strict Sandvik OEM specifications, guaranteeing perfect compatibility and reliable performance for your CH660.
Product Overview
Bearing 868.0799-00 is a 22224 E/C3 Spherical Roller Bearing. It is specifically designed for the main shaft assembly of the Sandvik CH660 cone crusher. Its primary function is to support the main shaft and withstand the immense radial loads and moderate axial loads generated during the crushing of hard materials.
Main Shaft Bearing’s spherical roller design provides excellent self-aligning capability, which compensates for minor shaft deflection or mounting misalignments. This protects the shaft and housing, extending the service life of the entire drive system. The C3 radial internal clearance is specifically engineered for heavy-duty machinery and high-temperature applications. It ensures optimal internal operating clearance is maintained even under high-speed operation and thermal expansion, preventing abnormal wear or seizure.
Manufactured from high-grade steel with advanced heat treatment, the rollers and raceways are precision-ground to achieve high dimensional accuracy and superior surface finish. This results in smooth operation, low noise, and extended service life. This bearing is a critical cone crusher part for ensuring the continuous, high-efficiency operation of your CH660 and minimizing unplanned downtime.
