1. Dedicated Measurement Equipment for Critical Parameters:

High-precision dynamic radial and axial clearance;
Precision bearing inner/outer ring rotation accuracy including inner/outer diameters and end vibration (dynamic measurement, conforms to national evaluation standards). Repeat accuracy is within 0.6μm – 1.5μm;
Precision bearing rigidity (optimizing structures by preloading and then measuring end face convex border). Air shaft loaded, the repeatability is within 1~2μm);
Matched bearing dynamic and static friction moments (of single bearings). The stability value of the air spindle shaft (support and rotary component) is 0.5mN·m/4h;
Bearing vibration (acceleration and… Read the rest

Aerospace and defense bearings, as an essential component of national defense and defense-related science and technology, are always ahead of civilian development. The bearing’s precision, selected materials and overall performance for military uses is far beyond the reach of the ordinary bearings. RHD Bearing has world-class bearing engineers, structuring methodologies, high-end testing approaches and failure analysis. By adopting dedicated military high carbon chrome bearing steel and advanced equipment, our products are excellent in all aspects and widely applicable for satellite, spacecraft, payload rocket, aviation life-support systems, short-to-mediumrange missiles and other… Read the rest
