QRE 60040USP UU 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 - QRE 60040USP UU 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.

QIBR - QRE 60040USP UU Crossed cylindrical roller bearing quality control

Dimension measurement: Use a variety of professional high-precision instruments to measure multiple dimensions of the bearing, with the highest accuracy of up to 0.001mm.

Rotation accuracy: Use a micrometer to measure small flaws or deviations on the bearing surface, with a measurement accuracy of up to 0.001mm.

Hardness measurement: Use a hardness tester to measure the surface hardness of the bearing, with a measurement accuracy of up to ±0.5HRC.

Metallographic analysis: Analyze the internal metallographic structure of the metal through a professional metallographic microscope.

Geometric tolerance: Use a profilometer to measure the bearing geometry and relative position.

Noise monitoring: Use a vibration meter to monitor the vibration during operation and obtain noise data.

Raw material control: Purchase steel and parts from suppliers certified by ISO 14001 to ensure product stability while promoting sustainable development.
