Large bearing mounting force required to significantly increase the price of self-aligning roller bearings, and hydraulic nuts should be used and / or the use of grease: 1. When using a hydraulic nut mounting a bearing, it is necessary to position it in a journal or sleeve threaded sector threaded barrel, the annular piston abuts the inner ring of the bearing, shaft nut or mounted on the shaft really a ring. By pump the oil into the hydraulic nut Spherical roller bearings picture, in a safe, precise installation force required to move the piston in the axial direction. Hydraulic nuts, spherical roller bearings mounted to the one-way bearing is free to rotate in one direction aligning roller bearings sales agents, while in the other direction to lock a bearing. One-way bearing metal case where a roller contains many, needle or ball, and the rolling seat (hole) is shaped so that it can only scroll in one direction, while in the other direction will have a lot of resistance. ramps and roller one-way clutch drum diameter substantially by the outer, inner ring with ramps and were subjected to a spring force, and always in close contact with the inner and outer rings consisting of a set of rollers. As long as one of the rotating raceway in the direction of its movement became impact on another industry, this arrangement ensures immediate and ensure the immediate ability to go beyond the speed of the drive from nature. Dongguan Spherical roller bearings manufacturers, Long Yu (certified), roller bearings provided by the Dongguan City, Long-Bearing Machinery Co., Ltd. Dongguan City, Long-Bearing Machinery Co., Ltd. (long-yu.net) Dongguan, Guangdong, thrust roller bearings leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the Long-leadership with the staff warmly welcome all inquiries negotiations to create a better future Long Yu.
