Innovative Separable Outer Ring Design

The separable outer ring design makes this line of bearings different from others on the market because it makes assembly and upkeep easier. This design makes it possible for techs to install or change bearings without taking apart nearby parts. This cuts down on downtime and makes maintenance easier. The inner ring that is built in keeps the rotary accuracy high, reaching micron-level accuracy that is needed for tough industrial uses. The thin-wall design keeps the structure's strength and load capacity while reducing both weight and room needs.

Comprehensive Size Range and Material Specifications

There is a wide range of sizes available to meet the needs of different applications. The inner diameters range from 20mm to 350mm, the outer diameters from 70mm to 540mm, and the widths range from 12mm to 45mm. These measurements make it possible for different types of tools to be set up in the same way, while still meeting performance standards. The bearings are made of high-quality Gcr15 and Gcr15SiMn materials, which are known for being very hard, resistant to wear, and stable in size even when used in a variety of situations.

Precision Accuracy Classifications
