KC Series Thin Section Ball Bearing Four Point Contact X-type
Product Overview:
KC‑X series is imperial‑standard Open‑type Constant Cross‑Section Four‑Point‑Contact Ball Bearing (Type‑X) from Kaydon Reali‑Slim portfolio, with fixed square cross‑section of 9.525 mm (0.375 inch), open‑type without seals. Adopting gothic‑arch raceway (Type‑X four‑point‑contact) geometry, one single bearing can accommodate radial load, bidirectional axial thrust and overturning‑moment simultaneously. It can directly replace two duplex angular‑contact bearings, reducing part count, saving axial installation envelope and simplifying mechanical layout.
Cross‑section dimension keeps constant regardless of bore‑size increase, realizing large‑bore, thin‑wall and lightweight construction. AR0 solid brass cage is standard. Compared with KAA‑X, KA‑X and KB‑X series, larger‑size rolling elements deliver obvious improvement on load‑carrying capacity, rigidity and anti‑tilting performance. Suitable for medium‑to‑heavy‑load precision rotary applications with combined loads and compact‑space constraints. Standard bore ranges from 4‑24 inches, widely applied in medium‑large robot joints, opto‑electronic tracking turntables, radar rotary mechanisms, large‑size semiconductor equipment, medical‑imaging machinery and aerospace systems 。
Applications:
medium‑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
medium‑to‑heavy‑load aerospace rotary assemblies
optical heavy‑duty indexing mechanisms
heavy‑duty precision test fixtures
automated medium‑large heavy‑load rotary platforms.
