NF Series Cross‑Section Thin-Section Ball Bearing
Product Overview:
NF series are imperial 0.75inch ( 19.05mm ) 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 ND series, ideal for precision equipment with large hollow bore, moderate load and limited installation space 。
