NSK UCFL210 2-Bolt Flange Housing Unit

The NSK UCFL210 is a 2-bolt oval flange housing unit combining an NSK FL210 insert ball bearing with a 50 mm bore in a compact oval flange housing, intended for shaft support positions where installation space or structural mounting provisions limit the use of the 4-bolt UCF square flange configuration. The oval flange profile with two bolt holes on the major axis provides a smaller mounting footprint than the UCF210 while using the same UC210 insert bearing with its self-aligning spherical outer surface and re-greaseable design. The 2-bolt UCFL arrangement is particularly suited to conveyor crossbar shaft ends, light machine frame shaft supports, and agricultural equipment roller shaft ends where a narrow-profile face-mounted bearing unit must fit within a limited structural width.

In Saudi HVAC and building services applications, the UCFL210 is used where shaft bearing support structures have limited bolt group space — for example, in inline fan shaft end bearing supports mounted to bracket steelwork with restricted access for four-bolt tightening, or in cooling tower fan shaft bearing positions built into compact tower cell frames. Commercial building HVAC contractors across Riyadh and Jeddah frequently specify both UCF210 and UCFL210 in the same air handling system, selecting the configuration based on the mounting structure geometry at each bearing position. The self-aligning insert bearing is identical between both configurations, simplifying spare bearing inventory management.

Saudi food processing and packaging machinery makes extensive use of UCFL210 units on conveyor chain shaft ends, roller bearing supports in product sorting lanes, and outfeed conveyor shaft end bearings where the oval flange's narrower profile fits within the machine frame side panel structure. For Saudi cement plant auxiliary equipment, the UCFL210 appears on narrower conveyor frames and lighter-duty transfer belt idler shaft end bearings where the full four-bolt UCF would create structural interference with the conveyor frame side profile. The re-greaseable design with accessible grease nipple is a practical requirement in all these applications given the high grease consumption rates under continuous dusty operating conditions.

Razz Middle East stocks NSK UCFL210 units alongside the UCF210 and other common UC-series variants, enabling supply of complete housed unit specifications for HVAC, conveyor, and general machinery applications from Saudi Arabian local inventory with fast delivery across the Kingdom.
