The legend of the deep groove ball bearings ！！
Deep groove ball bearing is the most commonly used rolling bearings. Its structure is simple, easy to use. Is mainly used to bear radial load, but when increase bearing radial clearanc...

Thrust ball bearings
Posted on 17 November 2011
Thrust ball bearing is separable including a shaft washer(fit with journal) a housing washer(fit with bearing block)a group of steel balls and a cage which make it very convenient to fit with journal and bearing block respectively. Cages: Cages of thrust ball bearing are pressed steel cages machined solid cages made of brass or bronze [...] Continue Reading

Four-row tapered roller bearings
Posted on 18 November 2011
Four-row tapered roller bearings are one of the mainly roll neck bearings and the capacity of their radial and axial loads is high. They can carry heavy axial loads in two directions, and their radial loads capacity is 3 times heavier than single-row tapered roller bearings. But the limiting speed is lower. They can [...] Continue Reading

Single-row tapered roller bearings
Posted on 18 November 2011
Tapered roller bearings are the most basic and widely used tapered bearing .And they have tapered inner and outer ring raceways between which tapered rollers are arranged. This type of bearings is particularly suitable for carrying of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the [...] Continue Reading

Full complement cylindrical roller bearings
Posted on 21 November 2011
Full complement cylindrical roller bearings have no cage and full of rollers, they can therefore carry very heavy radial loads. But, the high speed performance is worse compared with bearings with cage. Full complement cylindrical roller bearings include single row Full complement cylindrical roller bearings( type NCF) and double row Full complement cylindrical roller bearings [...] Continue Reading

Double row cylindrical roller bearings
Posted on 21 November 2011
Double row cylindrical roller bearings are separable bearings. All the bearing units can be separately. This makes it easier to mount and dismount. Double row cylindrical roller bearings have two structures of cylindrical and tapered bore. They mainly have 2 types: NN designs and NNU designs. Type of NN design has inner ring with two [...] Continue Reading

Single row cylindrical roller bearings
Posted on 21 November 2011
Single row cylindrical roller bearings are separable bearings. The rollers are guided by the two ribs of bearing rings. The bearings with cage are units comprising solid inner and outer ring together with cylindrical roller and cage assemblies. Therefore, these bearings are easy to be mounted and dismounted, especially where the load conditions are such [...] Continue Reading
