Single Row Tapered Roller Bearings in inch sizes

The single row tapered roller bearings have one row of tapered rollers resting on the guiding rib of the inner ring with their functional faces. Due to the great number of tapered rollers, these bearings have a high load rating capacity in the radial as well as axial directions. The axial load carrying capacity depends on the contact angle magnitude. The arrangement with single row tapered roller bearings is usually formed by a bearing pair. A single bearing can carry the axial load only in one direction. The bearings are separable. The inner ring (cone) with tapered rollers and a cage is one assembly unit. The outer ring (cup) is the other assembly unit. The single row tapered roller bearings are manufactured in metric dimensions as well as in inch dimensions.
