Applications:
This bearing is particularly well-suited for high-speed machinery including gearboxes, electric motors, machine tool spindles, compressors, pumps, and precision industrial equipment. The 35mm bore size makes it ideal for medium-duty power transmission applications. The bearing pair configuration with low axial clearance is especially valuable in applications requiring minimal axial play and enhanced rigidity. The open design is beneficial for applications where custom lubrication regimens or sealed housings are preferred, or where regular maintenance access is essential.
Note: As an open bearing, proper lubrication and contamination management are essential for optimal performance and extended bearing longevity. When used as bearing pairs in O- or X-arrangements, ensure correct spacing and clearance settings for optimal load distribution.
