Introduction

The Loose Ball Bearings are a type of rolling bearing. The bearing balls are installed between the inner steel ring and the outer steel ring and can withstand large loads. They are used to determine the relative position of two parts (usually the shaft and the bearing housing) and to ensure their free rotation, while transmitting the load between them as well. In addition, the radial clearance of the Loose Ball Bearings is small and can be eliminated by axial pre-tensioning, so they have high running accuracy. Their axial width is small, and some bearings can bear the combined radial and axial loads at the same time. The structure is compact and the combination is simple. Besides, they are standardized parts with a high degree of standardization and can be mass-produced to save costs. The Loose Ball Bearings can be used in various machines and equipment with rotating parts.

Production Line Process:

Heading: In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.

Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates.

Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision.

Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

Descaling: This step removes the residues and by-products from the heat-treating process.

Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001".

Lapping: Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade10 - 48.

Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
