608-2RS-C3 PFI Deep Groove Ball Bearing Sealed C3 Clearance (ID 8mm OD 22mm W 7mm)

PFI Fersa 600 Series Miniature Deep Groove Ball Bearings are single-row radial bearings designed for precise applications requiring small dimensions.

Key Specifications

These bearings follow the 600 series metric sizing, starting from sizes like 606 (inner diameter 6 mm, outer diameter 17 mm, width 6 mm) up to models such as 626 (inner diameter 6 mm, outer diameter 19 mm, width 6 mm). They use chromium steel rings and are available in open or sealed configurations compliant with JIS standards for tolerances. Typical dynamic load ratings range from 1,000-2,600 N, with static ratings around 400-1,000 N, depending on exact size.​

Construction Details

Balls are complementarily sized (e.g., 3.5 mm diameter with 7 balls in 626), enabling low-friction rotation for radial and light axial loads. Chamfer dimensions are standardized at 0.3 mm minimum. Reference inner and outer diameters support accurate mounting.​

Applications

Suitable for miniature machinery, electric motors, instruments, and light industrial equipment in power transmission systems. PFI Fersa produces these for automotive, industrial, and aftermarket use.​
