73×101.6×14.5/15.5 cassette-type inner rotary oil seal is engineered for DANA, Massey Ferguson, John Deere and New Holland agricultural machinery, directly replacing OE parts 2120605501 and 12018598B. Its half-packed structure balances rigidity and flexibility for a perfect fit in front axle installation space. The inner rotary design delivers outstanding resistance to mud and vibration under farm working conditions. Precision sizing ensures tight mounting on axle housing and half shaft, effectively preventing gear oil leakage even under long-term heavy-duty operation. Made of premium rubber, the seal offers superior anti-aging and wear resistance with firm installation, greatly reducing tractor transmission failures.
