What is a TB Seal? A TB seal is a type of radial shaft seal widely used in rotating equipment to retain lubricants and exclude contaminants. Characterized by its metal-cased construction and elastomeric sealing lips, this seal ensures reliable performance across diverse industrial applications. Below is a comprehensive overview of its design, materials, advantages, and […]

What is a TB Oil Seal? 1. Definition and Overview A TB oil seal is a T-type skeleton radial oil seal standardized under DIN 3760/ISO 6194. The designation “TB” reflects its design: TB seals are engineered to prevent fluid leakage along rotating shafts in low-contaminant environments, balancing cost-effectiveness, minimal friction, and reliable sealing performance. They […]

What is the Difference Between EPDM and FKM Seals? 1. Introduction EPDM (Ethylene Propylene Diene Monomer) and FKM (Fluorocarbon Rubber) are two dominant elastomers used in sealing applications, yet they serve vastly different roles due to their unique chemical and mechanical properties. This article provides a structured comparison of their compositions, performance, and applications, empowering […]
