                                                     KD Series Thin Section Ball Bearing  Angular Contact A-type

 

Product Overview:

KD 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 12.700 mm (0.500 inch). It is the extra heavy‑duty cross‑section grade among KAA‑KA‑KB‑KC‑KD 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 KC, KB, KA and KAA series, KD adopts larger‑size balls to achieve further improvement on load rating, rigidity and anti‑overturning moment. Preferred for heavy‑duty precision rotary mechanisms with large bore, limited installation envelope and strict requirements for load‑carrying capacity, anti‑tilting performance and rigidity. Bore sizes range from 4 inch to 30 inch, widely deployed in heavy‑duty high‑end equipment .

 

Application:

large heavy‑load robot joints

medium‑&‑large optoelectronic tracking gimbals

large‑size radar turntables

large‑format medical imaging equipment

heavy‑duty servo rotary tables

large semiconductor inspection stages

aerospace heavy‑duty precision actuators

astronomical instruments

large‑scale precision test turntables
