HIGH PRECISION MACHINE TOOL BEARINGS

2020-02-28

Precision machine tool bearings are mainly used in the main-shaft of machine tool, motor spindles, ball screw, rotary tables, etc. Precision Angular Contact Ball Bearings can reach P4 A class of rotational accuracy, and precision Cylindrical Roller Bearings can reach SP, UP class. Due to using optimization advanced configuration, special materials of rolling elements and cages, our products have characters of high precision, high speed, low vibration, long service life, etc.

1.High precision standard angular contact Ball Bearings

·Meet ISO and ZXZ quality standard, accuracy class reach P5, P4, P4A.

·Products of 71800, 71900, 7000, 7200 series.

·Contact angle is 15° A), 25° AC).

·Two kinds of cages selected according to the application, which are phenolic resin cage with outer rings centered and engineering plastics with rolling element centered.

2.High precision sealed angular contact ball bearings

·Specific designed for high speed rotation, low temperature rise, and maintenance-free.

·Contact angular is 15° A), 25° AC); And special customized design.

·Choose ceramic ball or steel ball as needed.

·Special high-temperature resistant rubber seal ring, filled with the grease which is suitable for ultrahigh speed.

3.Hybrid ceramic rolling element bearings

·Specific designed for high speed, corrosion resistance, high or low temperature, and lubrication on the demanding conditions.

·Advantages with low temperature rise, high rigidity, and long life.

·Rolling elements with high abrasion resistance that made from special ceramic materials.

4.Ultrahigh speed angular contact ball bearings

·High performance products developed for the application of high speed rotation, low temperature rise, super precision machining.

·Contact angle is 15°. Choose steel balls or ceramic balls, and design to deal with ultrahigh-speed application of dmn value 2 million or more.

·Products of 71800, 71900, 7000, 7200 and other series.

5.High precision matched angular contact ball bearings

·Matched angular contact ball bearings, including double, triple, multi-row, and other various arrangement forms.

·According the standard, ZXZ completed matching of the bore diameter, outside diameter, contact angles, projection etc. Before delivery, bearings can install and used directly by clients.

·The related dimension tolerance of universal matching bearing shall be controlled by 1/3 of Standard Bearings.

6.High stiffness of double row cylindrical Roller Bearings

·Applied for CNC controlled machine tools main-shaft with high speed, high rigidity and high precision.

·Cages are made from brass, engineering plastics, PPS(Polyphenylene sulfide),PEEK(polyetherether ketone)etc.

·Outer ring has Uniform circular oil hole for lubrication, the standard tapered bore design.

·Roller elements can adopt ceramic materials for high speed application.

7.High precision single row Tapered Roller Bearings

·Can bear both of radial and axial load, has great load capacity and high stiffness.

·Tapered roller bearings are separable bearings, so the cup and crown be used interchangeably.

·Optimizing the design of raceway, roller and rib shape, suitable for the relatively high speed.

·Two types dimensions: metric and inch.
