Canton, Ohio — The Timken Company will supply Qiqihar Railway Rolling Stock (Group) Co., Ltd., a leading Chinese railway wagon builder, with Timken AP-2 Class K railroad bearings for freight wagons.

Qiqihar Railway Rolling Stock produces more than 230,000 wagons in eight categories and 120 specifications, covering more than one third of the overall Chinese output.

“The Chinese rail market is an integral part in the growth of our global rail business,” said James M. Gresh, president of China-Timken. “Since the development of the first Timken rail bearing more than 70 years ago, Timken continues to support the global rail industry.”

The Timken AP-2 bearing provides improved service life under heavier loads compared to previous standard bearing designs. The AP-2 bearing axle design results in less axle flexure, which eliminates or reduces fretting wear between components and potential for the assembly to loosen in service.

The improved Timken HDL seal design provides the lowest torque in freight car service. In addition, the AP-2 bearing has fewer parts and features a more compact design. The seal wear rings have been eliminated; thereby eliminating fretting wear grooves under the seal wear ring and subsequent axle repair by plating.

“Timken produces good products, has good service and delivery. We believe Timken’s new bearing technology will increase the service life of our customers’ equipment,” said Yang Guohua, marketing manager of Qiqihar Railway Rolling Stock “The technical strengths of Timken and Qiqihar will provide our customers with more reliable service as well as reducing their operating and maintenance costs.”
