HIGHE PRECISION AUTOMOTIVE Tensioner Bearings
Tension bearings used in automotive engine belt pulley tensioning mechanism, and manufactured with tri-lip type seal structure, high temperature resistant rubber seals, fully synthetic special grease, and high-quality bearings steel, which are characterized by high temperature, high limiting speed and long life, Suitable for automobile engines that contact with water vapor, dust, mud, and work with heat, cold or other complex conditions.
APPLICATION FEATURES
1.High-speed running of bearing outer ring;
2.Temperature of operating environment above 100℃;
3.Surrounding of bearings with water vapor, dust;
4.Contact with mud frequently;
5.High rotation speed;
7.Operate of belt transmission; the rotation speed of bearings changes frequently during operation; force direction changes with belt swing; magnitude of load changes frequently--hearings have a greater impact of variable speed and variable load.
PERFORMANCE
1.High requirement of sealing performance: not allow water capor, dust, etc. leaking into the bearing;
2.Hign requirement of high-speed operation performance;
3.Excellent thermal stability at -40℃~150℃;
4.Starting torque: normally select medium contact seals;
5.Long service life: in accordance with the requirements of Automotive Bearings, testing life required more than 500h.
ADVANTAGE
The material selection of bearing components:
1. Rings manufactured by high-purity specialty quality bearing steel;
2. Steel balls are from famous brand manufactures, that effectively guarantee materials and processing accuracy;
3. Using glass fiber reinforced nylon cages;
4. Sealed with high quality acrylic rubber;
5. Using synthetic oil (base oil) + Polyurea (thickening agent) Grease.
DESIGN STRUCTURE
1. Sealed with tri-lips medium contact structure-- having a high sealing performance, and suitable for high-speed operation;
2. Using engineering plastic cages with oil reservoir structured --effectively increase the lubrication capability of bearings;
3. Optimize the groove curvature of outer ring and the raceway of inner ring-- adapt to high-speed performance and axial movement requirements.
