SeaSense Greaseable Zinc Plated Roller Shaft

The SeaSense Greaseable Zinc Plated Roller Shaft is a replacement boat trailer roller shaft (also called a greasable roller shaft or zerk roller shaft). It is made for keel, spool and bow rollers. The design is meant to outlast a conventional shaft, and it lets you lubricate the roller without taking it off the trailer.

Key Features:

• Grease fitting on each end: The patented design has a zerk fitting at both ends. You can lubricate the roller as the manufacturer recommends without removing it from the trailer.
• Zinc-plated steel: The plating protects against corrosion in marine environments.
• Versatile roller use: It works with keel rollers, spool rollers and bow rollers.
• E-clips included: The shaft comes with E-clips for retention.

Regular greasing helps keep rollers turning freely and helps prevent the seizing that salt and fresh water can cause. That makes this shaft a durable upgrade or replacement on a boat trailer.
