NC Series Thin Section Ball Bearing
Product Overview:
NC series are imperial 3/8‑inch ( 9.525mm ) constant cross‑section thin‑section ball bearings . The cross‑section dimension remains unchanged as bore diameter increases, balancing space‑saving performance and higher load capacity.
Rings and balls are standardly made of GCr15 (AISI52100) high‑carbon chromium bearing steel. 440C / 304 / 316L stainless steel and Endurakote hard‑chrome coating are optional.
Precision grades cover P4/P5/P6.
Three structures are available: Type‑A angular contact, Type‑C radial contact and Type‑X four‑point contact, capable of radial load, axial load and overturning moment.
Non‑standard customization per drawings & samples is supported. Dimensions are fully interchangeable with imported Kaydon NC series, ideal for precision equipment with large hollow bore, moderate load and limited installation space 。
Applications:
large heavy‑duty industrial robot joints
large‑size opto‑electronic tracking turntables
heavy‑load radar rotary mechanisms
large‑size semiconductor inspection turntables
large‑medical‑imaging rotary equipment
heavy‑load aerospace rotary assemblies
optical heavy‑duty indexing mechanisms
heavy‑duty precision test fixtures
automated large heavy‑load rotary platforms.
