294/670 EM Thrust Roller Bearings Features and Advantages

Allowable Misalignment Error: Thrust roller bearings possess self-aligning capabilities, allowing them to tolerate misalignment errors.

Load Capacity: The excellent fit between the rollers and the raceway enables the bearing to support heavy axial loads while also accommodating some radial loads.

High-Speed Capability: The cage design and the good fit between the rollers and the raceway make these bearings suitable for relatively high speeds.

Low Friction: By optimizing the contact at the roller end faces, friction heat generation is kept at a low level during high-speed operation.

Long Service Life: The special roller profile reduces edge stresses at the contact points between the rollers and the raceway.

Application: Thrust roller bearings are widely used in machine tools, aerospace, metallurgy and mining, heavy machinery, automotive industry, agricultural machinery, and power equipment.

Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearings, achieving a maximum precision of 0.001mm.

Rotation accuracy: Small surface defects or deviations are measured with a micrometer, with a measurement precision of up to 0.001mm.

Hardness measurement: Surface hardness is measured using a hardness tester, with precision up to ±0.5HRC.

Metallographic analysis: The internal metallographic structure of metals is analyzed using a professional metallographic microscope.

Geometric tolerance: The geometry and relative position of the bearing are measured using a profile projector.

Noise monitoring: Vibration during operation is monitored with a vibration meter to obtain noise data.

Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
