introduction：Double row deep groove ball bearingsThe design is basically the same as that of single row deep groove ball bearings。The raceway with the shaft shape of the deep groove ball and the excellent fit between the raceway and the steel ball。Double row deep groove ball bearings bear radial loads in addition，It can also withstand axial loads acting in both directions。 Standard double row deep groove ball bearings are4200A、4300Atype。AThere is no ball filling gap。Two reinforced nylon cages are inserted from each side of the bearing。Double row deep groove ball bearings in addition to having higher than single row deep groove ball bearings1.62Times the radial load capacity outside，It can also withstand axial loads。 Double row deep groove ball bearing features： Double row deep groove ball bearings are suitable for applications in a bearing configuration where the load capacity of a single row deep groove ball bearing is insufficient。For double row deep groove ball bearings with the same outer diameter and inner d

introduction：Metal linear bearingIt is a linear motion system produced at a low cost，For use with infinite stroke and cylindrical shaft。Widely used in precision machine tools、Textile machinery、Food packaging machinery、Sliding parts of industrial machinery such as printing machinery。 Due to the bearing ball contact with the bearing point，So the use of small load。The steel ball spins with very little friction resistance，Thus, high precision smooth motion can be obtained。 Plastic linear bearing is a self-lubricating linear motion system，The big difference with metal linear bearings is that metal linear bearings are rolling friction，There is point contact between the bearing and the cylindrical shaft，So its good for low loads and high speeds；And plastic linear bearings are sliding friction，There is a surface contact between the bearing and the cylindrical shaft，So this is suitable for high load and low speed movement。 1.1 Standard： The shape surface of the standard linear bearing is a cylindrical surface with hig
