NACHI (NACHI-FUJIKOSHI) Single row angular contact ball bearing 7304

- The balls and the raceways of the inner and outer rings come into contact at a certain angle to the radial direction.
- The bearings are non-separable, but because the balls are inserted from the counterbore side of the outer ring, they have more balls than deep groove ball bearings.
- Axial loads are limited to one direction, but they are suitable for carrying combined axial and radial loads.
- Because this bearing has a contact angle, an axial force component is generated when a radial load is applied, so it is generally used with both sides of the shaft facing each other or in combination.
