Auto Parts Spindle Bearing Sealed Angular Contact Ball Bearing 70, 72, 718, 719 for Machine Tool Sp

The precision angular contact ball bearings for spindles, have four 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.

CAEC 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.

CAEC 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 :

CAEC 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.

Performance characteristics of 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 spindle bearing: CAEC 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 angular contact ball bearing:

1. High-quality bearing materials: CAEC 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 CAEC have good product performance to ensure the optimal bearing configuration and smooth operation at high speed and quiet. CAEC 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. CAEC 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: CAEC mostly adopts bakelite cage, which can more effectively reduce the friction between metal and bearing balls and extend the life of the bearing. CAEC can also choose more suitable bearing cage materials according to customer requirements and bearing applications.

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

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

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

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

CAEC 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.
