The Timken Company manufactures a variety of bearings, alloy steels, and related components and assemblies that meet International Organization for Standardization (ISO) standards for quality assurance. Tiken 48750 Tapered Roller Bearing, Single Cup, Standard Tolerance... This cup is matched to its cone assembly based on the load that the bearing needs to support, and if the bearing needs radial internal clearance to accommodate thermal expansion. Founded in 1899, the Timken Company is based in Canton, Ohio. As part of a separable tapered roller bearing unit, this single cup has an open design that allows for lubrication and accurate adjustments. All rolling bearings are open, shielded, or sealed. Supports both radial and axial loads between a rotating and non-rotating member This single tapered roller bearing is for use in high-load, moderate-speed applications that include automotive axle systems and conveyor systems in heavy duty industries such as mining, construction and agriculture, among others. Specifications Tapered roller bearings--Boundary dimensions and series designationsISO 355Inch part numbering systemABMA standard 19.2Width tolerance standardsISO 492Tapered roller bearing naming conventionsISO 720Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others. Generally mounted in opposing pairs on a shaft to evenly distribute loads, this single tapered roller bearing assembly is stable in temperatures ranging from -54 to 120 degrees C (-65 to 250 degrees F). This Timken 1700 Series single cup is matches with a single cone (inner ring assembly, sold separately) to assemble into a complete single tapered roller bearing, suitable for applications that support both radial and axial loads.
