The R series refers to a specific series of deep groove ball bearings designed to inch dimensions. This series is widely used in the United States and other countries that adopt the inch measurement system. The R series typically includes bearings with bore diameters ranging from 0.1875 inches (4.7625 mm) to 1.5 inches (38.1 mm).
R series inch-size deep groove ball bearings are a special type of deep groove ball bearing designed specifically for applications requiring inch measurements.

When installed on a shaft, the R series inch deep groove ball bearings limit axial displacement of the shaft or housing in both directions within the bearing's axial clearance, allowing for bidirectional axial positioning. Furthermore, these bearings exhibit a certain degree of self-alignment and can operate normally even when tilted 2' to 10' relative to the housing bore.
1. Open bearings are those without any sealing caps.
2. Closed bearings are those with sealing caps on both sides. ZZ designates metal caps on both sides. Customers can select different sealing caps based on their requirements.
3. Within the same bearing size, customers can select different materials and grades.
4. The following inch-size ball bearing catalog represents basic dimensions according to international standards. Custom designs are available for specific requirements. Please contact our engineers for more information on bearing technology.
