90 x 125.25 x 10 mm. Compatible with Volvo (Part Nos. 948642 / 9486424); CORTECO (12014746B); DT Spare Parts (2.35054); Elring (577.991 / 587.991).
Suitable for Volvo classic heavy-duty truck series: F10, F12, F16, NL10, NL12.
Modern mainstream trucks: Volvo FH12, FM12, FM7, FM9, FM10, etc.
Light/medium-duty trucks: Volvo FL6, FL7, FL10.
Construction machinery (articulated haulers/medium-duty axles): Volvo CE (Construction Equipment) models including A20C, A25D, A25E, A25F, A25G, A30D, A35D, and A40D through A40G (virtually the entire articulated hauler range); typically functions as the pinion seal for rear or intermediate axles (e.g., models EV72, EV87).
Core function—Static and dynamic sealing: Prevents heavy-duty gear oil (such as high-temperature, high-pressure 85W-90 oil) inside the differential housing from seeping or being flung out along the high-speed rotating pinion shaft, ensuring adequate lubrication for the differential gears.
External dual-protection: Prevents external contaminants—such as mud, water, heavy dust, and road debris—from entering the differential during highway driving or construction site operations, thereby avoiding gear oil contamination and accelerated bearing wear. Given the harsh operating environments of heavy-duty trucks, OE-grade seals typically utilize fluoroelastomer (FKM/Viton) material to withstand the high temperatures generated during sustained high-speed and long-distance driving.
