EZ-Lube Function

The EZ-Lube system uses a grease fitting (zerk) located at the end of the spindle. When grease is pumped through the fitting, it travels through internal passages to lubricate both the inner and outer wheel bearings. This:

• Reduces maintenance time.
• Helps prevent bearing failure.
• Allows routine greasing without removing the hub assembly.

Typical Applications

• Utility trailers
• Equipment trailers
• Cargo trailers
• Boat trailers (especially with galvanized hub options)
• Landscape trailers
