Long-term maintenance of low torque effect! Contributing to the global environment with low friction technology in oil seals.
The "TF Coat" is a technology that coats the sliding parts of the lip with microparticles of PTFE, a low-friction material. By applying fine PTFE particles in a thin layer, the adhesion to the base material, FKM, is enhanced, resulting in excellent wear resistance. This technology achieves a reduction of approximately 30% in low torque compared to conventional methods, maintaining sealing performance while preserving effectiveness over the long term. 【Features】 ■ Special technology: Low-friction coating ■ Low torque: 30% reduction compared to conventional methods ■ Suppression of sliding heat generation: Achieving long lifespan ■ Sustainability: Maintenance of long-term effectiveness *For more details, please refer to the PDF document or feel free to contact us.

An oil seal for large diameters that excels in resistance to eccentricity and impact. 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 flat spring (SUS) and a coil spring, allowing the rubber surface to slide against the flat spring on the back side of the lip, resulting in excellent followability. Additionally, by using a superior special rubber at the tip of the sealing lip, it has significantly improved performance and design compared to the SM type (new JIS), with the key characteristic being its excellent sealing capability even with a shaft runout of 2.00mm and a peripheral speed of 20m/sec. 【Features】 ■ High-speed motion and large followability ■ No worry about spring detachment (as the coil spring is wrapped around the flat spring) ■ Large eccentricity ■ Special formulation of sealing lip material (excellent wear resistance, good compatibility with the shaft even under high-speed rotation, and long lifespan) ■ Sturdy seal (strongly pressed on the metal surface, with minimal deformation during installation or storage) *For more details, please contact us or download the catalog.
