Do you know what items need to be done for bearing inspection?

Release time:


Bearing (Bearing) is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient (friction coefficient) during its movement, and ensure its rotation accuracy (accuracy).

Bearing detection range

Ceramic bearings, needle roller bearings, joint bearings, linear bearings, high temperature bearings, self-lubricating bearings, motor bearings, fan bearings, hub bearings, sliding bearings, thrust bearings, angular contact bearings, spherical bearings, deep groove ball bearings, thrust ball bearings, roller bearings, joint bearings, combined bearings, rolling mill bearings, etc.

Bearing inspection items

Anti-grease leakage performance detection, fatigue life detection, hardness detection, surface quality (abrasion, damage, scratch, burn, rust), residual magnetic intensity detection, rotation flexibility detection, chemical composition detection, composition analysis, industrial diagnosis analysis, failure analysis, cause analysis, hardness test, top calcination test, low-magnification defect analysis, fracture analysis, non-metallic debris detection, decarburization layer analysis, microstructure analysis, microscopic void analysis, clearance detection, accelerated life test, temperature test, wear amount test, inner hole test, metallographic structure test, appearance test, impact strength test, heat resistance temperature test, crack test, strengthening test (load), temperature rise test, vibration test, drawing test, material analysis, metal grade identification, component detection, simulated environmental test (high temperature, low temperature, temperature shock (gaseous and liquid), immersion, temperature cycle, low pressure, high and low temperature and low pressure, constant damp heat, alternating damp heat, high pressure cooking, sand dust, explosion resistance, salt spray corrosion, gas corrosion, mold, rain, solar radiation, light aging), rotation speed detection, axial load detection, radial load detection, lubricity testing, extreme high and low temperature testing, dustproof testing, carbide inhomogeneity analysis, physical performance analysis, mechanical performance analysis, surface quality evaluation, tensile strength, elongation at break, compression set, wear, adhesion strength, impact toughness, fracture failure analysis, etc.
