SKF Nitrile Rubber (NBR) Seal, 12 mm ID, 25 mm OD, 7 mm

This radial shaft seal is designed to efficiently seal between rotating and stationary components, preventing oil or grease leakage. The product features a nitrile rubber material which allows it to perform reliably across a temperature range of -40°C to +100°C. With dimensions of 12mm inside diameter and 25mm outside diameter, this robust sealing solution ensures longevity and effectiveness in various mechanical applications.

• Robust nitrile rubber construction enhances durability and performance

• Used in rotary requiring effective lubrication management

The rubber outside diameter provides enhanced flexibility and adaptability, ensuring a tight fit within the housing bore. This design choice allows for effective sealing even when there is slight misalignment or movement between components.

The non-contacting auxiliary lip helps to create a barrier against dirt and contaminants, enhancing the overall sealing effectiveness. This additional protection is crucial for maintaining the integrity of the seal in polluted environments, thus prolonging its lifespan.

The seal can function within a temperature range of -40°C to +100°C, with the capacity for short-term exposure up to 120°C. Its permissible circumferential speed reaches a maximum of 2.05 m/s, making it suitable for various industrial applications.

Its design features allow for limited misalignment, meaning it can maintain effective sealing even if the shaft is not perfectly aligned. This characteristic ensures reliable operation in dynamic environments where movement is common.
