KF Series Thin Section Ball Bearing Four Point Contact X-type
Product Overview:
KF‑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 19.05 mm (0.750 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, KB‑X, KC‑X and KD‑X series, larger‑size rolling elements deliver superior load‑carrying capacity, structural rigidity and anti‑tilting performance. Suitable for extra‑heavy‑duty precision rotary applications with combined loads and compact‑space constraints. Standard bore ranges from 4‑32 inches, widely applied in ultra‑heavy‑load robot joints, large‑size opto‑electronic tracking turntables, heavy‑duty radar rotary mechanisms, large‑size semiconductor equipment, large‑medical‑imaging machinery and heavy‑duty aerospace rotary assemblies。
Applications:
extra‑heavy‑duty industrial robot joints
large‑size heavy‑load 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
extra‑heavy‑duty industrial robot joints
large‑automated large-size heavy‑load rotary platforms.
