200x230x19 PU+NBR-BA Seal Description

The YNF17152 200x230x19 PU+NBR-BA Seal is a heavy-duty composite oil seal designed for large hydraulic shafts used in excavators and industrial machinery. By combining polyurethane (PU) and nitrile rubber (NBR), this seal delivers excellent wear resistance, strong oil retention, and stable sealing performance under demanding working conditions.

The PU element provides high abrasion resistance and mechanical strength, while the NBR component ensures superior oil resistance and elasticity. The BA-type structure enhances sealing efficiency during shaft rotation and helps maintain consistent contact pressure over long service periods.

Widely applied in hydraulic systems operating under high load and continuous duty, the YNF17152 composite seal is an ideal replacement choice for maintenance workshops and aftermarket distributors seeking reliability, durability, and extended service life in large-diameter sealing applications.
