353130 b type compact bearings main characteristics

Main characteristics of 2020-353130 b type compact bearings 01 - 30 for railway truck with rolling bearings, generally USES no axle box double row tapered bearing units, through the bearing saddle directly connected with the bogie side frame. Because there was no axle box double row tapered bearing unit with light structure, convenient assembly, maintenance is convenient wait for a characteristic, has been widely used in railway wagon. In order to further meet the needs of railway truck speed, overload, improve the reliability of using bearing developed compact bearings. In January 2006, CTBU150 type compact bearings technology have been introduced into China and established the standard of 353130 b type bearing, the design of 353130 b type bearing, in May 2006, 353130 b type bearing loading is applied, realize the localization of 353130 b type bearing. 353130 b type bearing cancelled the seal seat; Use of the low friction type LL oil seal; In the block and bearing inner ring between the big end installed a tech baffle, eliminates the inner ring and block contact after micro abrasion; Design the rated life of not less than 200 & times; 104km。 Mixer main features low cancelled the seal seat compact design. The journal of the compact design to shorten, reduce the bending deformation of shaft. Low tech cage provides the operating temperature of the lower, more stable and safe failure mode. Race and penal inspection special pocket hole design, convenient for bearing the general maintenance. * LL oil seal to ensure the low friction torque. To prevent oil spill and micro vibration abrasion particles and other impurities into the bearing. After low tech baffle to reduce inner ring and block the microvibration contact friction abrasion. （ Source: the resources of railway vehicle platform)
