Ball bearing is a kind of rolling bearing with high speed, low friction and high mechanical efficiency. Standardized size, easy to replace, because of its advantages of stable quality, high precision, long service life, etc, it is widely used on the market. The ball bearings provided by QIBR received great positive feedbacks from customers.
The accuracy level of ball bearing is generally divided into P0(ABEC 1)/P6(ABEC 3)/P5(ABEC 5)/P4(ABEC 7)/P2(ABEC 9).
Ball bearings generally consist of a pair of rings, a set of cages and several balls. The ball bearings have a simple structure and is easy to use. They are the bearings with large production volume and widely used in industries.
Ball bearings are mainly used in motors, fitness equipment, roller shoes, scooters, agricultural machinery, motorcycles, electric bike, mechanical parts, high-end toys, etc.
Ball bearings after opening from outer package should be installed and used immediately, and should not be exposed in the air for too long.
The storage place of ball bearings should be dry and tidy. Sweat on hands when handling ball bearings will cause rust easily. Please wear gloves.
When replenishing or replacing new grease, check whether the original grease is invalid or whether the grease contains foreign matter. If it is invalid or the grease contains foreign matter, remove the original grease before adding the clean grease.
100Cr6 ball bearings: Bearing steel has high and uniform hardness and wear resistance, it is the most widely used, and the cost is lower than the other two materials. It is commonly used in machine tools, locomotives, motors and miniature bearings for aviation field.
Stainless steel ball bearings: Compared with GCr15 bearings, stainless steel bearings have the characteristics of not easy to rust, low noise, washable and corrosion resistant, and can work in liquid environments. The main application areas are medical equipment, cryogenic engineering, optical instruments, and food processing machinery.
Ceramic ball bearings: The advantages of ceramic ball bearings are corrosion resistance, light weight, long life, insulation, resistance to deformation, high temperature resistance, and low friction coefficient. It can work under various special and demanding conditions such as high temperature, high cold, deep cold, flammable, explosive, strong corrosion, vacuum, non-magnetic, and dry friction.
