Size parameter:
The 6 in the 608 bearing represents the 6 series deep groove ball bearing, 0 is the size series, 8 is the inner diameter size of 8mm, if the bearing is a standard part, the outer size is usually one, the old model is expressed by 80018.
The outer diameter is 22mm, the height is 7mm and the inner diameter is 8mm. 7 steel balls, ball diameter 3.969mm. But there are non-standard, size according to user specifications manufacturing requirements, few on the market, high cost.
Bearing material:
The 608 bearing with dustproof cover and sealing cover, with dustproof cover is indicated by model suffix zz (608zz), and the glue cover is indicated by model suffix 2RS(608-2rs). Materials are carbon steel, bearing steel (GCr15), stainless steel, plastic, ceramic and so on. Cage: nylon cage, iron cage, copper cage and so on.
Advantages of deep groove ball bearings:
Deep groove ball bearing has the advantages of low manufacturing cost, simple structure, variety and so on. It is widely used in various industries and is one of the more commonly used bearings. It has the following characteristics:
1. Small friction coefficient, high speed.
2.The size range is wide, with a certain aligning ability.
3.Simple structure, low manufacturing cost, mass production, can achieve high precision.
4.Can bear large radial load, when the radial clearance increases, can bear two directions of alternating axial load.
5.In reasonable maintenance and use of the environment of high durability, low maintenance cost.
Application:
The 608 bearing can be used for: Motors, air conditioners, scooters, fidget spinners, single-stage reducer, plastic welding machine, lace machine, sliding guide rail, flotation equipment, automatic sand blasting machine, indentation machine, rubber cutting machine, dripping shot machine, weaving machine, drainage and irrigation machinery, reaction tank, concrete mixer, whole ironing equipment washing equipment, automatic pump, bottle blowing machine, rolling equipment, radial drilling machine, and so on.
