Product Description

1. Product Overview

445/440A is standard imperial single row tapered roller bearing, composed of separable inner cone (445) and outer cup (440A). It supports combined heavy radial load and unidirectional axial thrust. Usually installed in opposed paired arrangement to withstand bidirectional axial forces. Separable cone & cup design simplifies assembly, disassembly, inspection and periodic re-lubrication. Widely applied on heavy-duty truck wheel hubs, agricultural tractors, harvesting machinery, light engineering equipment and medium-heavy load reduction gear assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.
