here are major problems, poor sealing performance

At present, the domestic automobile generator bearing quality levels compared with foreign advanced level in the medium and low, there are major problems, poor sealing performance, product life is low, the reliability is not high, especially when mass production is difficult to meet the high-end customers at home and abroad requirements. Domestic production of such good basic bearing life 8 to 12 million km, individual enterprises can reach 14 to 16 million km, but with first-class foreign mainframe customers 200,000 km above requirements differ greatly, not with internationally renowned Bearing Company competition.
Over the years, Morse Group company although production in the automotive alternator Roller bearing accumulated a lot of valuable experience, but the product still exist, such as sealing performance is unstable, life expectancy is low, not high reliability. Technology Center technicians after careful research and analysis, based on the experience of the original, targeted for the product design and manufacturing process improvements, the processing of the product for an effective process control, using a more reasonable means of inspection, and with reference to well-known companies of the product with the requirements of the experimental design. The main work carried out are described below:
Product design: the use of today's popular internationally renowned bearing ring groove curvature radius of the center of rotation diameter design methods, in order to ensure the same work process bearing radial clearance smaller axial clearance can reduce the noise and machinery functions consumption, reduce the ball and raceway wear and improve bearing operation stability; seal with three lips two chambers, the motion compensation type patent structure, using high temperature resistance, abrasion-resistant rubber seal materials to improve sealing performance to meet life requirements; lubricating materials using the higher cost of automotive alternator bearings for high temperature resistance, long life grease.
Process design and process control: optimizing the process parameters, drawn up to ensure the size and shape of the seal groove processing methods; special heat treatment process to ensure the stability of the tissue material to improve the accuracy of the bearing; implementation of process control to ensure product parts dimensional stability of the processing.
