An oil seal for large diameters that excels in eccentricity resistance and impact resistance. It seals even with an eccentricity of up to 2.3 mm.
The "SAS type" oil seal, designed for eccentricity resistance, features a combination of a plate spring (SUS) and a coil spring, allowing the rubber surface to slide against the plate spring on the back side of the lip, resulting in excellent followability. Additionally, the use of a superior special rubber at the tip of the sealing lip significantly enhances performance and design compared to the SM type (new JIS). Its maximum characteristics include maintaining good sealing even with a rotational speed of 20 m/sec and an eccentricity of 2.00 mm, ensuring it follows the shaft's movement effectively. 【Features】 ■ High-speed operation with great followability ■ No worry about spring detachment (as the coil spring is wrapped around the plate spring) ■ Large eccentricity ■ Special formulation of sealing lip material (excellent wear resistance, good compatibility with the shaft under high-speed rotation, and long lifespan) ■ Sturdy seal (strongly pressed on the metal surface, minimizing deformation during installation and storage) *For more details, please contact us or download the catalog.
