KF Series Thin Section Ball Bearing Angular Contact A-type
Product Overview:
KF Series is imperial‑standard Open‑type Constant Cross‑Section Type A 30° Angular‑Contact Thin‑Section Ball Bearing from Kaydon Reali‑Slim portfolio, with fixed square cross‑section of 19.05 mm (0.750 inch). It is the extra‑heavy‑duty large cross‑section grade among KAA‑KA‑KB‑KC‑KD‑KF product lineup . Cross‑section dimension keeps constant regardless of inner‑diameter change. Standard version is open construction without seals, normally supplied with AR0 machined solid one‑piece brass cage.
Single‑row two‑point 30° angular‑contact construction accepts combined radial load and unidirectional axial thrust load. Single bearing cannot withstand alternating bidirectional thrust load. Two bearings shall be duplex‑mounted (DF face‑to‑face / DB back‑to‑back) for bidirectional load capacity and adjustable axial preload.
Compared with KD, KC, KB, KA and KAA series, KF adopts larger‑size balls to achieve significant improvement on load rating, rigidity and anti‑overturning moment. Preferred for extra‑heavy‑duty precision rotary mechanisms with extra‑large bore, limited installation envelope and strict requirements for load‑carrying capacity, anti‑tilting performance and rigidity. Bore sizes range from 4 inch to 40 inch, widely deployed in large‑size heavy‑duty high‑end equipment .
Application:
extra‑heavy‑duty robot joints
large‑size optoelectronic tracking turntables
ship‑borne / vehicle‑mounted large radar turntables
large‑format medical CT imaging equipment
extra‑heavy‑duty servo rotary tables
extra‑large semiconductor inspection stages
aerospace extra‑heavy‑load precision actuators
large astronomical telescope instruments
heavy‑duty weapon test turntables
large‑scale precision heavy‑load test equipment.
