NACHI 62/28C3 Open Deep Groove Ball Bearing 28x58x16 mm, C3
Available
The NACHI 62/28C3 is a single row deep groove ball bearing with open (no seals or shields). It measures 28 x 58 x 16 mm (bore x outer diameter x width) and carries a basic dynamic load rating of 17,900 N and a basic static load rating of 9,750 N.
Deep groove bearings are the most widely used ball bearing type: they carry radial, axial and combined loads and run at high speed with high running accuracy. This one has a radial internal clearance of C3 (13 to 28 µm radial).
Where this product is used
- Electric motors and generators
- Pumps, fans and blowers
- Gearboxes and industrial transmissions
- Conveyor rollers, idlers and pulleys
- Power tools, appliances and general industrial machinery
Features
- Open design with no seals or shields: lowest friction, oil or grease lubrication, and the oil limiting speed applies
- Carries radial, axial and combined loads, with high running accuracy and high speed capability
- C3 radial internal clearance (13 to 28 µm for a 28 mm bore), larger than Normal
- Basic dynamic load rating 17.9 kN, static 9.75 kN, with NACHI boundary dimensions to the ISO/JIS standard plan

Selecting the right option
Open bearings suit housings that provide their own sealing and lubrication, and are the only type with an oil lubrication speed. For clean, well-protected housings they give the lowest friction.
Fitting and use
Check the load and speed against the catalogue figures in the table before ordering, and apply a suitable safety factor. These bearings must always carry a minimum radial load so the balls roll rather than slide, and heavy axial loads should be checked with AIMS before ordering.
Press the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and the outer ring in a housing.
