Product Description

The Nachi H-E30306DJ is a single row tapered roller bearing designed to handle combined loads, supporting both high radial loads and axial loads in one direction.

Its steep contact angle (D suffix) provides increased axial load capacity compared to standard tapered roller bearings, making it suitable for demanding applications such as automotive and industrial gear arrangements.

The J suffix indicates interchangeable rings, allowing the cone and cup to be matched within the same series, which is useful for service and replacement.
