DICHTA Oil Seal 118x150x12 AS NBR is a premium rotary shaft oil seal designed for industrial gearboxes, pumps, electric motors, conveyors, compressors, and heavy-duty machinery. Featuring the AS Profile with a spring-loaded primary sealing lip and additional dust lip, this seal provides excellent lubricant retention, superior contamination protection, and long-term reliability in demanding industrial environments. The DICHTA AS design combines a garter spring sealing lip with an auxiliary dust lip for enhanced sealing performance.
The DICHTA 118x150x12 AS NBR Oil Seal is engineered for rotating equipment requiring dependable sealing performance, protection against contamination, and long service life.
The AS Profile is one of DICHTA's most widely used industrial oil seal configurations. It features a rubber-covered outer diameter with an internal metal reinforcement, a spring-loaded sealing lip, and an additional dust lip. This dual-lip construction helps retain lubricants while simultaneously preventing dust, dirt, moisture, and abrasive particles from entering the equipment.
The primary sealing lip is energized by a precision garter spring that maintains consistent radial pressure against the shaft surface. This ensures effective sealing performance even under continuous-duty operation, vibration, and varying temperatures. The auxiliary dust lip acts as a secondary barrier against external contamination, helping extend the life of bearings, shafts, gears, and other critical rotating components.
The rubber-covered outside diameter improves sealing between the housing bore and the seal itself while simplifying installation and reducing the possibility of leakage around the outside diameter. Internal metal reinforcement provides dimensional stability and secure retention in the housing.
Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR is widely recognized throughout industry for its durability, flexibility, abrasion resistance, and cost-effective sealing performance.
With dimensions of 118 x 150 x 12 mm, this seal is commonly used in industrial gearboxes, pumps, electric motors, conveyors, compressors, steel mills, mining equipment, and OEM machinery utilizing metric shaft systems.
