Structures：rollers, cage assembly, shaft washer and housingwasher
Applications：Thrust cylindrical roller bearings are mainly used in heavy machinery, high-power marine gearboxes, oil rigs, vertical motors and other machinery.
Most of QIBR thrust roller bearings are separate bearings, which are very convenient to install and disassemble. It is used to support axial and radial combined loads dominated by axial loads. The axial loads are mostly unidirectional, and most of the thrust roller bearings are single row bearings. According to different structures, thrust roller bearings are divided into thrust cylindrical roller bearing, thrust tapered roller bearing, thrust needle roller bearing, and thrust spherical roller bearing. Thrust roller bearings are suitable for occasion with relatively low rotational speed.
The outer dimensions of QIBR thrust roller bearings conform to GB/T273.2 "Genera plan for the outer dimensions of rolling bearing thrust bearing", GB/T4663 "Dimensions of rolling bearing thrust cylindrical roller bearings", GB/T5859 "Dimensions of rolling bearing thrust spherical roller bearings" and other regulations.
The tolerance of QIBR standard thrust roller bearings meets the requirements of GB/T307.4 "Tolerance of rolling bearing thrust bearing", JB/T7751 Rolling bearing thrust tapered roller bearing and other standards.
The dimensional tolerance grade of QIBR thrust roller bearings is generally made according to P0 (normal grade). If customers have other special requirements (including non-standard) for size, tolerance and clearance, QIBR are able to provide the corresponding product.
QIBR non-standard customized thrust cylindrical roller bearing
Non-standard thrust cylindrical roller bearing customization is a main part of QIBR categories. It can be customized according to the customer's working conditions or the place where the bearing works. Internally we can optimize and improve the design of the thrust cylindrical roller bearing, which can improve the loading capacity and service life of bearing. For example, the thrust cylindrical roller bearing can be made into a double row structure bearing, which can reduce rollers sliding in the cage pocket. It is also possible to design and manufacture new types of thrust roller bearing products that meet the customer's individual requirements. Our QIBR enables non-standard thrust cylindrical roller bearings to operate safely and smoothly with precision roller selection and bearing raceway production, to achieve optimum bearing performance.
