NTN UCF209 Mounted Bearing Unit Flanged Housing Unit 45 × 49.2 mm

Overview

NTN UCF209 Industrial Bearing is a core machine element that reduces shaft friction and supports loads to improve equipment efficiency and service life. It should be selected according to load direction, speed, and mounting space in motors, pumps, gearboxes, conveyors, and other machinery.

Bearings typically consist of inner ring, outer ring, rolling elements, cage, or sliding contact surfaces, with seals, shields, housings, or sleeves added depending on type. Lubrication and sealing conditions have a major impact on performance.

Selection guidance

Select by shaft diameter, load direction, speed, mounting space, sealing/lubrication condition, and compatibility with the existing part number.
