The material is made of Daye special steel, and the content of impurities (sulfur, oxygen, non-metallic inclusions) is very low. High temperature bearing steel and carburized steel can also be used. Material available for selection
2: Increase without price: the inner and outer rings of the bearing are thickened. The bearing weight increases to ensure the durability of the bearing. No increase in price
3: processing accuracy (determining the smoothness of operation)
Dimensional tolerance (inner diameter, outer diameter, width) : the implementation is ISO/ABEC standard, CpK value control is very good, installation without selection, direct installation, with the same clearance
Rotation accuracy (beat) : measure the radial beat of the inner ring and the end face beat. The run-out value is controlled in the micron level, which is suitable for high speed or high surface finish.”
Roughness: Surface roughness of raceway and roller (Ra value). We use the superfine process
Bearing housing upgrade: The bearing housing has been upgraded to ensure that the contact surface and force point between the bearing housing and the equipment have been increased to ensure the stability of the bearing housing.
Fourth, clearance and matching (determines the working temperature and life)
The gap controls the range of the C3 gap, group matching
5. Noise and Vibration (determining sensory quality) Vibration value (acceleration/speed)
100% Anderon meter test, eliminate any product with noise.
Six, heat treatment and surface modification (determination of wear resistance)
Hardness and depth of hardened layer
Heat treatment processes (such as martensite, bainite quenching) ensure uniform hardness (HRC 61-65), and the effective hardening layer is deep
Stability of dimensions
For high temperature conditions (such as dryer, motor), we carry out special stabilization treatment, bearing size will not change significantly at high temperature, to prevent locking.
Seven, seal and lubrication
Our filling oil brands (such as ExxonMobil, Shell) and filling volume is accurate, with precision weighing and fat injection technology (to avoid uneven fat injection resulting in fever)
Viii. Packaging protection:
Single box packing sealed with plastic film,
