Product Description

The UMSBKW8-28 Seal, part of the UMSBKW8 Series Seal family, is a high-performance 28mm Shaft Seal designed for industrial applications requiring reliable shaft sealing in demanding environments. It supports sealing for rotating shafts up to 28mm in diameter, with compatibility for standard lubrication systems and mechanical assemblies. Engineered for durability, it operates efficiently in temperatures ranging from -40°C to +120°C and withstands moderate pressure variations. Ideal for automotive, heavy machinery, and manufacturing sectors, its key advantages include robust abrasion resistance, extended service life, and ease of installation. A potential limitation is reduced effectiveness in extreme dynamic misalignment conditions. Constructed with advanced elastomer materials, this seal ensures minimal leakage and optimal performance under continuous operation.
