The LM603049AS/LM603012 Imperial single-row tapered roller bearings mainly consist of an outer ring, inner ring, tapered rollers, and a cage. The outer and inner ring assemblies are separable for easy installation and adjustment. The rollers make line contact with the raceways. The cage is typically made of stamped steel or brass.

Imperial single-row tapered roller bearings can simultaneously withstand radial and unidirectional axial loads, exhibiting high load-bearing capacity and rigidity. Their separable structure facilitates clearance adjustment and preload control, resulting in a high limiting speed. They conform to imperial standard dimensions and offer excellent interchangeability.
