QIBR - 294/670 EM Thrust Roller Bearing Characteristics
294/670 EM Thrust Roller Bearing, long life, strong adaptability. 294/670 EM Thrust Roller Bearing, can withstand unidirectional or bidirectional axial loads and a certain overturning moment, suitable for mechanical equipment with high durability requirements.
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.

High-Performance Materials: Suitable materials can be selected based on customer requirements, such as 52100, 100Cr6, SUJ2, etc.
Cage Selection: Customers can choose from various cage materials based on their application needs, including machined brass cages, stamped steel window cages, and machined copper cages.
Grease Selection: Lubricants can be chosen according to the operational requirements of the bearings, such as SKF LGET 2 or Shell Gadus S5 V142W 00.
Further Customization: QIBR can design and optimize thrust ball bearings according to customer usage conditions and requirements.
QIBR - 294/670 EM Thrust Roller Bearings Quality Control
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.
