The genuine Western 94536 Flange Bearing serves as a high-capacity mechanical support component engineered to stabilize the rotational tracking of the main conveyor shaft. Measuring exactly 1.125 inches (1-1/8″) in inner diameter, this factory-original bearing features a robust 2-bolt housing pattern with a 4-5/8 inch bolt hole center-to-center mounting distance. Commercial fleet mechanics install this heavy-duty flange bearing on the conveyor drive or idler shaft assemblies of Western Tornado, Striker, and Ice Breaker series hopper spreaders to replace worn, grinding, or seized bearings before extreme winter ice storms demand high-volume de-icing dispatch.
This factory-authorized bearing assembly is engineered with a specialized sealed insert casing to withstand continuous contact with highly abrasive bulk de-icing materials. The heavy-duty cast housing mounts directly to the outer spreader framework, maintaining precise shaft alignment under the extreme down-pressure loads of multi-ton salt or sand capacities. The integrated grease zerk allows for routine preventative lubrication maintenance, purging corrosive moisture, salt brine, and fine road debris out of the internal ball path to eliminate premature mechanical drag.
For professional winter maintenance contractors and municipal fleet managers, executing a proactive replacement on sloppy or rough-turning flange bearings avoids severe drivetrain torque damage and unexpected field breakdowns. This durable 2-bolt bearing serves as a direct drop-in replacement across Douglas Dynamics family hopper spreaders, including Fisher Polycaster and SnowEx Renegade poly and stainless steel V-box configurations. Integrating this authentic factory component ensures your conveyor pintle chain or belt tracks cleanly, preserving the service life of your electric drive motors and gearboxes.
Benefits of the Western 94536 Flange Bearing
