In the utility model, described seal ring is contact sealing ring, and described contact sealing ring comprises sealed outer ring, skeleton, in described sealed outer ring, skeleton is set.

In the utility model, described bearing outer ring inboard arranges interior engaging groove, and the outside engagement groove that described bearing inner race arranged outside and interior engaging groove are complementary, described bearing outer ring are connected interior engaging groove and are connected with outside engagement groove with bearing inner race.

In the utility model, on the contacted corner angle of each end face of described interior engaging groove, outside engagement groove, bearing inner race and bearing outer ring and side, arc transition is set respectively.

In the utility model, the internal diameter of described bearing inner race is 27mm-33mm; The external diameter of described bearing outer ring is 57mm-67mm; The thickness of described bearing outer ring is 14mm-19mm.

In the utility model, the internal diameter of described bearing inner race is 30mm; The external diameter of described bearing outer ring is 62mm; The thickness of described bearing outer ring is 16mm.

Beneficial effect

The bearing of a kind of water jet loom of the utility model, compared with prior art, for the water jet loom performance characteristic, the water jet loom bearing of design specialized by reducing ball diameter, thereby improves ball density in raceway, reach the effect of stable transfer power, simple in structure, very practical, realize the purpose of this utility model.
