Technical Specifications

Product Description

The UC1306 TAM KOYO cylindrical roller bearing is engineered to deliver outstanding radial load capacity and long service life in demanding operating environments. Cylindrical rollers create line contact with the raceways, allowing considerably higher radial load ratings than comparable ball bearings while maintaining precise shaft positioning.

This bearing is widely used in automotive driveline systems and industrial power transmission equipment where durability, reliability and accurate guidance are essential. The optimized internal geometry promotes smooth operation, minimizes stress concentrations and contributes to extended operating life.

Manufactured to KOYO's high quality standards, the bearing offers consistent performance in OEM production as well as maintenance and repair applications.
