Material

High-Carbon Steel Load Type: Radial and Axial Pack Quantity: 1 Unit Tolerance Class: ABEC-1 Standard Surface Finish: Ground and Polished

Applications

Heavy-duty electric motors and generators Industrial gearboxes and speed reducers Mining conveyor systems and crushers Steel rolling mills and metal processing lines Pulp and paper manufacturing machinery Large agricultural equipment and harvesters Pump and compressor assemblies Wind turbine main shafts Railway traction motors Construction equipment drivetrains This bearing series represents a critical component for facilities requiring robust motion control solutions. The 5.12-inch bore allows for direct integration with standard large-diameter shafts commonly found in heavy industry, eliminating the need for custom adapters or complex mounting arrangements. The 11.02-inch outer diameter provides a stable housing fit that distributes load evenly across the support structure, reducing stress concentrations that can lead to premature housing failure. With a width of just 2.28 inches, the design offers a high load-carrying capacity without excessive bulk, allowing engineers to maximize power density within their machine designs. The steel material selection guarantees structural integrity even under shock loading conditions typical in mining or primary metal production. Proper installation and lubrication according to industry standards will ensure years of dependable service, protecting your capital investment in downstream machinery. This single-unit packaging facilitates easy inventory management for maintenance teams replacing individual components during scheduled overhauls or emergency repairs.
