Abstract

The invention discloses a seamless steel pipe for a bearing. The seamless steel pipe comprises a steel pipe body, wherein the steel pipe body comprises an outer pipe body and an inner pipe body; a plurality of bearing connecting grooves are formed in the inner pipe body; a plurality of annular convex rings are arranged at the upper end of the outer pipe body; a connecting flank is arranged at the bottom of the outer pipe body; the connecting flank and the outer pipe body are integrally molded. According to the seamless steel pipe for the bearing, the connecting stability of the steel pipe can be improved, and the seamless steel pipe is long in service life and simple in structure.

Description

technical field [0001] The invention relates to the field of seamless steel pipes, in particular to a seamless steel pipe for bearings. Background technique [0002] With the improvement of living standards, most of the machinery and equipment in the processing and transportation industries have extremely high safety and reliability requirements for equipment materials. The original ordinary stainless steel materials and processing technology may not be able to adapt to the modern industrial environment for logistics and other industries. Security and reliability requirements. The original steel pipes are easily corroded during use, and the strength of the steel pipes is relatively weak, which shortens the service life of the steel pipes. The replacement, installation and maintenance of the steel pipes are more troublesome, and there are also defects in the unstable connection with the installation connectors. Contents of the invention [0003] The technical problem main...
