88*123*23.5 Inner Rotary Maintenance-Free Oil Seal For CONMET Axle

88*123*23.5 oil seal is an inner rotary maintenance-free hub seal engineered for CONMET axles. Its inner rotary lip rotates synchronously with the hub, creating a stable oil film under high speed and heavy load, while keeping mud, water and dust out of the bearing for true maintenance-free operation. The rubber-coated metal shell fits tightly into the hub bore, eliminating typical leakage of conventional iron-shell seals and perfectly suiting long-haul service. Made to strict OE standards, it installs directly without modification and serves as an ideal replacement for CONMET maintenance-free hubs
