Description
Heavy-duty radial shaft seals built for industrial gearboxes operating under dust, vibration, and long duty cycles—helping cut leakage risk and keep lubrication clean.

Heavy-Duty Radial Shaft Seal for Industrial Gearbox Use

Built for tough gearbox conditions

Designed for industrial gearboxes exposed to dust, vibration, and extended runtime, this heavy-duty radial shaft seal helps retain lubricant and reduce contamination ingress for more stable operation.

Key advantages

  • Optional dust lip for abrasive environments

  • Wear-resistant elastomer choices to extend service life

  • Stable sealing force via spring-energized lip design

  • Custom sizes available for OEM replacement and maintenance
