What is the Drawn Cup Series?

The Drawn Cup Needle Roller Bearing (HK for open ends, BK for closed ends, e.g., HK0709) features a thin-walled, hardened steel outer ring that is deep-drawn from sheet steel. This design is intended to be press-fitted into the housing, requiring no further axial fixation. It is a cost-effective solution for applications where the housing bore cannot be used as a raceway.

Key Advantages & Features

• Cost-Efficiency: High load capacity achieved through a simplified manufacturing process.

• Press-Fit Mounting: Secured by interference fit, eliminating the need for snap rings or shoulders.

• Thin Section: Provides a hardened raceway in housings made of light alloy or thin-walled tubing.

Application Areas

Commonly found in domestic appliances, automotive steering systems, office equipment, and power tool transmissions.

Solutions Provided

When your housing material is too soft (like aluminum or plastic) to act as a raceway, the HK/BK Series offers a "hard-shell" raceway solution that is both economical and space-saving.
