1.Bearing materials

mainly include carbon steel, stainless steel, bearing steel, copper, iron, etc.Carbon steel material bearing, is characterized by low prices, use situation is not too high, to the requirement of bearing is suitable for low speed and light load.After carburizing and carbonitriding process for surface strengthening and with high strength and hardness, high elastic limit and fatigue limit.Compared with the ordinary bearing steel, stainless steel bearing material has more advantages, high hardness and more rust and corrosion resistence, especially suitable for the bad production environment, to bear ability;High service life;Maintenance free.Our stainless steel ball bearings have two options, customers can choose high hardness and corrosion resistance of these two aspects.Bearing steel bearing after heat treatment, precision grinding processing, has the high hardness, tensile strength, contact fatigue strength and wear resistance, a toughness, meet the certain conditions on the properties of corrosion resistance and high temperature resistant requirements.Copper bearing anticorrosion, various environment and general, but not heavy. 

2.the outer plastic aprons

Outside of synthetic device on the bearing, and through the bearing relative to the pulley frame rotation.Outside of synthetic material generally adopts engineering plastics as raw materials, parts and adopt wear-resisting metals as raw materials.High-grade pulley of aprons made of has anti-aging performance of materials, and is mixed with the lubricant materials, aging resistance and self-lubrication greatly improved, so as to improve the smoothness of the pulley use, reliability and security.We can according to the specific application requirements, through the change of the specifications of the raw materials, varieties and formulation, and synthesis of the required performance of the product.Outside of plastic aprons qualitative light, high flexibility, good shock absorption, sound performance, good corrosion resistant ability and low dynamic friction coefficient, good chemical stability.Yuan cheng outside the aprons by injection molding, injection molding, the outer surface effectively, adopt lathe processing, to ensure the smooth appearance and a good concentricity and roundness.

 3.rolling element

Rolling body generally choose glass ball, stainless steel and ceramic ball.With not sex grease on the ball, so can easily push and pull, smooth and flexible, and large bearing capacity, deformation pressure, wear-resisting.

 4.cage

retainer with glass fiber reinforced nylon 66 (PA66) and PE or higher performance engineering plastics, carbonated steel plating, achieve environmental protection standard. 

5.dust cover and seal ring

bearing adopts metal dust cover, or the rubber sealing ring.Is suitable for the environmental impact load is bigger. 

6.plastic bearing inner and outer ring material

generally adopts engineering plastics as raw materials, parts and adopt wear-resisting metals as raw materials.High precision plastic bearing generally adopts precision CNC processing, bearing on the accuracy and tolerance is better.Many conventional plastic bearing is with direct injection forming, convenient for forming solid with high cost performance.(pulley to use this technology in general) used in low speed, medium load situations.In the toy industry, fitness equipment industry, furniture industry, medical machinery industry, advertising industry has been widely used, etc.
