IMPERIAL BALL BEARINGS
XLS series bearings are designed with compact sections for application where space is restricted in mounting. XLS series replace as Alternatives to inch dimension ball bearings of RHP XLJ series and TIMKEN conrad type BIC series bearings. They are mostly delivered with open type as their use is common to see in pumps and gear boxes, oil bath performs lubrication in an enclosing housing. KIHOI also developed this series with metal shields or rubber seals for other else industrial applications where solid greasing is adopted. Shield/sealed type appears only for items with bore size less than 12.5inch.

XLS series are equivalent to RHP brand XLJ imperial deep groove ball bearings for gearbox as statement by site聽 https://www.nsk.com/eu-en/industries/gearboxes, and Torrington BIC series bearing designated as聽https://www.timken.com. Timken BIH series inch dimension bearings are the further generation of BIC series, they are designed with filling slot to permit more balls, therefor they are capable to carry higher load. Kihoi produces BIC series bearing with ceramic balls for the out-put of a speeding up gearbox application.
