Miniature bearings usually refer to a class of bearing products with an inner diameter of 1-9mm or inch sizes from 1.016 to 9.525mm. Miniature deep groove ball bearings are widely used. According to the size and structure of the bearings, the major bearing companies in the world have slightly different model numbers. There are differences. The Japanese NMB bearing type designation letter + outer diameter size + inner diameter size allows users to intuitively understand the product specifications. Others, such as NSK bearings, are marked as MR bearings. The method adopts international standards, which is more common in the industry. Miniature ball bearings, compact structure, small installation space, low starting torque, often used in high-speed, low-noise product parts. Youwei bearing has high processing precision and can provide bearings made of vacuum degassing bearing steel. The material has low oxygen content, high purity, more wear resistance and oxidation resistance. We can provide stainless steel bearings or stainless steel ceramics according to different application scenarios of users. Mixed structure bearings, miniature bearings of other materials. Can also provide miniature flange bearings, miniature thrust bearings, or customized non-standard bearings according to customer requirements.
Excellent micro-precision miniature ball bearings, high precision, low noise, low starting torque, according to customer needs, provide the following structural and quality requirements:
1. Accuracy grade: P0, P6, P5, P4, P2, can provide small clearance bearings according to supporting needs
2. Sealing form: open type (no cover), metal dust cover (ZZ), rubber sealing ring (2RS).
3, speed: can provide high-speed bearings, such as dental drill bearings, the maximum speed of 450,000 rpm.
4, retainer: there are steel stamping cages, stainless steel cages, nylon cages to choose from
5, inner and outer rings and balls: bearing steel, stainless steel, ceramics, etc.
Application of miniature bearings:
Suitable for aeromodelling drones, micro motors, PTZ motors, dental drills, crushers, stepper motors, massage chairs, pusher motors, computers, wall breakers, sports equipment, fitness equipment, robots, mechanical equipment, household appliances , Medical equipment, precision instruments and other industries.
We are a professional cixi good bearings manufacturers and china small ball bearings factory.
