KG Series Thin Section Ball Bearing Four Point Contact X-type
Product Overview:
KG‑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 25.4mm (1.000inch), 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 remains constant regardless of bore‑size increase. It maintains 25.4mm square cross‑section even for large bore sizes, realizing large‑bore with thin‑wall lightweight construction. AR0 solid brass cage is standard. Equipped with largest‑size rolling elements within this product family, it delivers maximum load‑carrying capacity, structural rigidity and anti‑tilting performance. Suitable for extra‑ultra‑heavy‑duty precision rotary applications with large combined loads and compact‑space constraints. Standard bore ranges from 4‑40 inches, widely applied in ultra‑heavy‑load robot joints, large ship‑borne opto‑electronic tracking turntables, large‑size radar rotary mechanisms, over‑size semiconductor equipment, special medical‑imaging machinery, heavy‑duty rotary assemblies and large‑size test‑simulation turntables.
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.
