Product Description

Zys Auto Parts Spindle Bearing Sealed Angular Contact Ball Bearing 70, 72, 718, 719 for Machine Tool Spindle, CNC Machine, Motor, Gas Turbine, Robot Industry

Product Description

The CZPT precision angular contact ball bearings for spindles, have 4 size series,718,719,70 and 72. With the same inner diameter, the outer diameters and the widths of 718,719,70 and 72 series increase in turn.  

ZYS precision angular contact ball bearing with 15 ° (C) and 25 ° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore ,the spindle, with high speed and small axial load ,should adopt the 15 ° angular contact ball bearings,whereas the 25 ° angular contact ball bearing should be adopted.

ZYS precision angular contact ball bearings with high-speed angular contact bearings (standard series), super-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings.

Types and performances of angular contact ball bearing :

ZYS precision angular contact ball bearings with high-speed angular contact bearings (standard series), super-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings.

Our Advantages

HangZhou Bearing Research Institute Co., Ltd.,since1958, is the only
state level comprehensive research institute in China’s bearing
industry. We have total assets of 2.06 billion RMB, own 1 research
and development center, 3 industrial bases and cover an area of
more than 47 hectares. We have advanced bearing manufacturing
equipments and world first class testing equipments and have solid
strength in manufacturing, measuring and testing of bearing and
related components with high precision and high reliability. We have
more than 380 technical staff of bearing related disciplines, thus we
maintain a leading position in the aspects of bearing design, basic
theoretical research, lubrication technology, metallic and non-metallic materials, testing and industry standards.

Performance characteristics of CZPT spindle bearing: Ultra high speed, high stiffness, high carrying capacity, good running performance, easy mounting of universally matchable bearings, suitable for oil and gas lubrication or injection lubrication.

Applications of CZPT spindle bearing: ZYS super high speed single row angular contact ball bearings might be used in the fields of machine tools, textiles, automobiles, railways, metallurgy, chemicals, electronics, Industrial pumps, Compressors, Material Handling, Electric motors.

Product features of CZPT angular contact ball bearing:

1. High-quality bearing materials: ZYS adopts ultra-clean steel, high purity high-carbon chromium bearing steel GCr15 from a well-known domestic manufacturer, which can extend the life of the bearing by 80%.

2. High quality bearing rolling elements: The bearing balls provided by CZPT have good product performance to ensure the optimal bearing configuration and smooth operation at high speed and quiet. CZPT has a complete process production line, from powder ultrasonic pre-dispersion, mixture mixing, spray drying granulation, near-net-size molding, cold isostatic pressing, GPS-HIP combined sintering process, high-precision grinding and processing, total quality inspection to packaging. CZPT has a comprehensive quality control system, quality identification of raw materials and auxiliary materials, quality control of mixed materials, quality control of pressing and sintering, and quality control of finished products.

3. More suitable bearing cage: ZYS mostly adopts bakelite cage, which can more effectively reduce the friction between metal and bearing balls and extend the life of the bearing. CZPT can also choose more suitable bearing cage materials according to customer requirements and bearing applications.

4. Advanced lubrication technology: ZYS uses high performance grease and advanced lubrication technology to extend bearing life and improve bearing performance.

5. Ultra finished raceways: ZYS uses special honing to minimize noise, improve lubricant dispersion and increase bearing life.

6. Contact angle: ZYS ultra high speed precision bearings usually use 15°and 25° contact angles.

7. Accuracy grade: ZYS can offer the high precision angular contact ball bearings with P2, P4A, P4 grade.

ZYS Precision Bearing Quality Control and Assurance:

Austrian AICHELIN heat treatment equipment and long-life heat treatment process provide a strong guarantee for the continuous and reliable operation of bearings.
