TSB rolling bearings – four row cylindrical (tapered) roller bearings are mainly applied for Bar, Wire Rod and Hot Strip Steel Mills, also widely used in the heavy duty & green energy industry as well.

About TSB

About TSB

Since its inception in 1970, from an early start with gearbox made to now capable of the Bar Mill design and manufacturing, we always hold the spirit of factory motto-“Extensive Study for Practical Purposes”, even to set machinery automation into production technology. Stay, all the time, running research program for customer service and problem solved. The evolution of Company originating in Yitai Gear to Han Chun machinery to today’s own brand “TSB“, would keep on using our best efforts to fully meet quality requirements, by plentiful experience as well as strict process control.

Each TSB bearing and component, shall be ensured every action, such as material procurement, machining process, follow-up measurement, heat treatment and packaging design … etc, to be implemented under controlled conditions and product outputs which might achieve International Standard.
