Bower Bearings 560 552-A Tapered Roller Bearing

Bower Bearings 560/552A is a one‑row tapered roller bearing in the TS (Tapered Single) imperial family, engineered to carry combined radial and axial loads in compact, high‑load assemblies. The design uses a single row of tapered rollers with raceways that converge toward a common point on the bearing axis, enabling smooth rotation and predictable service life in demanding equipment. Key dimensions for this size are a bore of 66.675 mm (2.625 in), an outer diameter of 123.825 mm (4.875 in), and a width of 38.1 mm (1.50 in). In NTN’s 4T‑560/552A variant, the cage is described as pressed steel, a durable configuration that supports reliable operation in high‑speed or heavy‑load service. This bearing is widely used in applications requiring imperial‑sized, single‑row taper bearings and serves as a direct replacement for worn 560/552A units in compatible housings and shafts. Dimensional figures are reported in both metric and imperial catalogs, and exact tolerances can vary by manufacturer—consult the specific supplier’s datasheet to confirm fit for your machine.
