Wheel hub oil seal 100x129,85x12,5/14 RWDR K7 NBR

The hub seal from the renowned Italian manufacturer Corteco, part of the Freudenberg Sealing Technologies (FST) group, is a highly specialised shaft sealing ring intended for work in exceptionally harsh environmental conditions, where there is a lot of dust and a risk of heavy contamination. Construction and principle of operation Double casing: The seal consists of an inner casing pressed onto the shaft, which acts as the running surface for the mating outer casing. Labyrinth system: The integrated labyrinth arrangement of sealing lips effectively retains: -external contamination (dust, mud, sand, filings), -grease leakage to the outside - maintaining its correct level inside the system. No shaft treatment: The innovative design eliminates the need to harden or grind the shaft surface, which significantly simplifies and speeds up installation. Application The product is used, among others, in: hubs of excavators and construction machinery, equipment exposed to intense contact with mud, water, dust and aggressive particles. Seal dimensions: • Inner diameter: 100 mm • Outer diameter: 129,85 mm • Seal height: 12,5/14 mm Technical parameters: • Working pressure: ≤0,05 MPa • Maximum speed: ≤4 m/s
