Single row tapered inch roller bearings: composite load carrying components in inch sizes
Single row tapered inch roller bearings are the basic category of the tapered roller bearing family that adopts inch size standards. The core feature is that the rolling elements are conical and the inner and outer ring raceways are tapered. They adapt to the installation size requirements of inch equipment and can withstand radial loads and unidirectional axial loads at the same time. They are widely used in North American standard automobiles, agricultural machinery, engineering machinery and other fields, and are the key support for composite load scenarios in inch transmission systems.
From a structural point of view, this type of bearing has the same principles as metric single-row tapered roller bearings. It consists of four parts: an inner ring (with tapered raceway and ribs), an outer ring (with tapered raceway), tapered roller, and cage. The core difference lies in the dimensioning and adaptation standards. Its imperial dimensions include inner diameter (d), outer diameter (D), and width (B), all in inches (for example, model 30205 imperial system corresponds to an inner diameter of 25.4mm = 1 inch), and the raceway taper and roller taper angle need to match the shaft diameter and bearing seat of the imperial equipment. Specifications; the inner ring ribs are used to limit the axial movement of the rollers, and the cages are mostly made of stamped steel plates (medium-low-speed, low-cost scenarios, such as agricultural machinery) or brass materials (high-speed, heavy-load scenarios, such as American heavy-duty truck rear axles) to ensure even distribution of rollers and reduce friction and collisions. Since a single set of bearings can only bear one-way axial load, in practical applications, they need to be installed in pairs "face-to-face" or "back-to-back" to form a two-way axial limit.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
