Overview

The Bower BCA LM300811 is a tapered roller bearing designed for heavy loads. It consists of a two-piece cup and cone assembly, where the outer ring is the cup and the inner ring, rollers, and cage assembly form the cone. This detachable design allows the bearing to support both axial and radial forces.

The LM300811 is ideal for environments with high speeds, heavy loads, and a need for low friction. Its applications include gearboxes, hoisting equipment, rolling mills, mining industry machines, and various axle types such as steer, drive, pusher, and tag axles, as well as engines and propellers.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
