Product Description

Deep groove ball bearings are the most commonly utilised rolling bearings, belong to non-separated bearings, which are easy composition, easy to use and minimal price tag. Fundamental deep groove ball bearings are composed of inner ring, outer ring, metal balls, and cage. The cages are mainly stamped metal corrugated cages or engineering plastic reliable cages, although huge bearings use metal strong cages.

There are 2 kinds of deep groove ball bearings, single-row and double-row. The structure is also divided into 2 types: open up variety and closed sort. The open kind implies that the bearing is not sealed the closed kind indicates that it has seal. There are 2 types of sealing framework: dust-evidence seal and oil-evidence seal.          


Double row deep groove ball bearings are equivalent in layout to solitary row deep groove bearings. It consists of outer ring, internal ring, cage and double row metal balls. Double row deep groove ball bearings mostly bear radial hundreds and can also bear bidirectional axial masses.

Double row deep groove ball bearings are appropriate for bearing preparations where the load ability of a solitary row deep groove ball bearing is insufficient. For the double row deep groove ball bearing with the very same outer diameter and internal diameter as the deep groove ball bearing, its width is more substantial and the load potential is also considerably greater than that of the solitary row deep groove ball bearing of the sixty two and 63 collection.

Double row deep groove ball bearings can only tolerate an angular misalignment of 2 minutes of arc. Bigger angular misalignment can overload the balls and raceways, shorten bearing existence, and result in elevated sounds.


Main applications:
Cars, agricultural equipment, machine instruments, motors, water pumps, textile CZPT and other fields.
