Product Details

The Dutton-Lainson 21768 is a precision-engineered grease seal designed specifically for trailer wheel hubs with 3/4-inch spindles. This essential component provides a critical barrier between your trailer's wheel bearings and the outside environment, protecting against water intrusion, dirt, and road debris.

Key Features:

  • Designed for 3/4-inch trailer spindles
  • Compatible with LM11949/LM11910 bearing applications
  • Double-lip seal design for superior protection
  • Spring-loaded construction retains grease inside the hub while keeping contaminants out
  • Precision-manufactured to ensure proper fit and long service life
  • Ideal for boat trailers, utility trailers, and other light-duty trailer applications

Proper sealing is critical for maintaining wheel bearing health and preventing premature failure. The Dutton-Lainson 21768 grease seal is manufactured to exacting standards to provide reliable protection in demanding marine and road environments. This seal is commonly used in trailer bearing kits for 3/4-inch straight axle spindles and pairs with standard LM11949 tapered roller bearings.
