6310 NR NSK Ball Bearing 50x110x27 with Snap Ring

Main Description

The 6310 NR NSK ball bearing 50x110x27 is a single-row deep groove ball bearing with a groove and retaining ring, designed for high load capacity and secure axial positioning in industrial applications.

Within the deep groove ball bearings 63xx series, the 6310 NR NSK model is engineered for heavier-duty systems compared to the 62xx range. Its robust construction allows it to handle higher radial loads while maintaining stable performance at medium to high speeds. The integrated groove and snap ring enable quick axial fixation in the housing, eliminating the need for additional locking components and simplifying assembly.

The 50x110x27 bearing size is commonly used in medium to large industrial machinery where durability and reliability are critical.

Construction and Design

The 6310 NR NSK bearing is built for strength and long-term performance.

Key design features:

• single-row deep groove ball bearing
• precision-machined groove in the outer ring
• retaining ring included for axial locking
• high-grade bearing steel for extended service life
• steel cage ensuring stable operation
