Smith Roller Cone Bearing

Smith Roller Cone Bearing

This is a replacement tapered roller bearing cone for the main drum roller assembly on rear discharge concrete mixers. It is a standard 455 series bearing cone that pairs with a 453A bearing cup to handle both high radial and axial (thrust) loads from the rotating mixer drum. This component is essential for ensuring the smooth and stable rotation of the drum. It is a critical wear part that requires replacement when the bearing becomes worn, noisy, or fails, to prevent damage to the roller and pedestal.
