GMN offers a complete range of sizes, types and designs with its spindle ball bearings in standard sizes S, SM and KH. In conventionally oil-lubricated spindle bearings, lubricant is supplied through a lateral oil supply. GMN spindle bearing designs +A, +AB, +L and +LB provide direct oil supplies to the lubrication point through a bore in the outer ring. GMN spindle bearing designs +AG ensure the highest possible machine running times without complex oil supply systems. These feed the lubricant directly into the lubricating point through holes in the outer ring. The developed high-performance, separable BNT and BHT designs ensure fast and uncomplicated handling, especially with regard to assembly and maintenance.

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Small Rolling Frictional Resistance Incorporating a ball with high accuracy into the precisely polished external cylinder results in small rolling frictional resistance and extremely smooth rolling motion together with reciprocal motion. Low Inertia Since the retainer has high rigidity and is lightweight, it has low motion inertia, making it suitable for rolling motion and reciprocal motion in highspeed operations. A Variety of Models Standard and heavy load models are available, each with different load ratings, and each offered with or without seals. It is easy to choose the right product based on the specifications of your machine or device.
