Meritor Standard Wheel Seal
The Meritor Standard Wheel Seal protects trailer wheel bearings by stopping lubricant migration and contaminant ingress. This seal features a thick, stiff steel case that resists installation damage and a multi-zone labyrinth design with rubber wipers and waterproof grease to block dirt, water, and road debris. A low-friction bumper reduces torque during break-in, while the large crumple zone absorbs heat and helps maintain seal stability. Constructed with NBR rubber components, the standard version provides reliable sealing for trailer applications. By using the Meritor MER0143 wheel seal, fleets extend bearing life and reduce maintenance intervals.
