Cross Tapered Roller Bearing-Imperial Seris - QXR496051
QXR496051 Crossed Cylindrical Roller Bearing Product Features and Advantages
High load capacity: It can withstand large radial and axial loads and is suitable for high-load application scenarios.
Small size and large load: The cross-arranged rollers can effectively distribute the load, and the bearing provides greater load capacity at a smaller size.
Low friction: The contact surface between the cylindrical roller and the raceway is large, the friction coefficient is low, and energy loss and heat generation are reduced.
High precision: The bearing structure is optimized to improve the rotation accuracy of the bearing and is suitable for applications requiring high precision.
Application: It has a wide range of applications in industrial robots, machine tools and CNC machine tools, aerospace, medical equipment, optical instruments, IC manufacturing equipment and other fields.
QIBR - QXR496051 Crossed Cylindrical Roller Bearing Optimization
High-performance materials: The bearing material can be replaced according to the working requirements of the bearing, such as stainless steel, silicon-manganese steel, etc.
Structural optimization: The one-piece inner ring and outer ring are designed with mounting holes, without flanges and bearing seats, and easy to install.
Sealing structure: The sealing structure can be selected according to the working environment of the bearing, such as FKM/fluoro rubber seals for high temperature resistance, hydrogenated nitrile rubber (HNBR) seals for low temperature resistance, and polyetheretherketone (PEEK) seals for chemical resistance, to ensure the heat resistance, oil resistance, and chemical resistance under different working conditions.
Grease replacement: QIBR technicians can recommend grease according to the working conditions of the bearing or replace grease according to customer needs, such as Mobil, Shell, SKF, Fuchs and other brands.
More customization: QIBR can design and optimize the bearing structure and process according to customer requirements for drawings and bearings.
