Thin-Section Bearing (GRA Series) - 1

Product Description

SZY thin wall bearing recently developed to replace imported products bearing characteristics, and each of its series of cross-sectional size was designed to a fixed value, with a series of cross-sectional size is unchanged, it does not increase the diameter size increase for modern mechanical design of rotating bodies compact, lightweight and simplify requirements. It is a small size, light weight, low friction characteristics, widely used in aerospace, precision machine tools, industrial turntable, radar communications, industrial robots, semiconductor processing equipment, optical processing equipment, medical equipment, textile machinery, and other fields, These devices can significantly save space and reduce weight, reduce friction, and provide good rotation accuracy. At present, the development of SZY bearings used in thin-walled China Electronics Technology Group, the Institute's major imports semiconductor devices used as a substitute for imports bearing products.

SZY light-cylindrical roller bearings is the characteristic development product of our company to replace imported products. The bearing use in he flexible operation of the key components of military radar, to achieve high-precision, negative clearance, low friction torque activated technology related requirements.

It has also been used in Harmonic Drive, inside and outside of the bearings have positioning holes, double-thread linking the outer ring, the inner ring as a whole; Rollers are 90°, 1: 1 cross-arranged, the overall high-strength steel stamping maintain -. It has high capacity, high torque rigidity, a lower start friction torque characteristics.

It has also been used in the rotary stage of Yasukawa Robot base, size of 480 mm diameter, high precision bearings processing, and rolling of the Rotary flexible, which is up to positioning requirements of robot arm. Bearing also features a sealed, and played a good fat and prevent leakage into the external debris bearings.
