Since developing the Spherical Bearing Spindle in 1978 this division has continued development and remodeling, and has produced approximately 5,000 spindle units to the present. The high precision and reliability fostered by this long manufacturing experience know-how garners high praise from customers.
This division has supplied approximately 1,000 units as high precision / high speed cutting and grinding spindles to customers leading the leading-edge technology. In the future this division will continue to develop and improve, answer divergent customer demand.

Features

Typical structure of Aerostatic Bearing Spindle	Porous restrictor equipped

For spindle bearings, annular restrictors and porous restrictors are provided. Optimal bearing system for applications is equipped. The right figure shows the porous restrictor structure.
Large reduction of air consumption is possible with the porous restrictor, and our company has traditionally achieved a 1/6 ratio to convention.
