Tinmy Cylindrical Roller Bearings For Features and Benefits


Cylindrical Roller Bearings are manufactured in a number of designs; the predominant type being the single row roller. The roller and cage assembly are guided axially by the integral flanges (ribs) on one of the bearing rings. This design facilitates ease of mounting and dismounting, particularly where both races are an interference fit on their seating. Roller bearings with flanges (ribs) on one race only do not provide any end location.

Various Roller Bearings with ribs on both races provide axial location, and are capable of carrying light or intermittent axial loading. These patterns are of the NJ, NUP, NJ and HJ types. If used for axial location and light axial loads the contact between the flanges (ribs) and the roller ends is that of a sliding bearing, not rolling bearing, therefore lubrication is of paramount importance. Double row and full complement Cylindrical Roller Bearings are also manufactured .


By virtue of the line contact between rolling elements and raceways, cylindrical roller bearings have high radial load capacity and are suited for high-speed applications. With a patented high strength cage design in pressed steel our cylindrical roller bearings are comprised of machined brass or polyamide and offer low noise,low heat generation and, for more arduous applications, can be supplied in a range of advanced special materials.
