White Keel Roller Ø75 mm for Trailer – 14 mm Axle Hole
This white Ø75 mm keel roller is an essential part for smaller trailers designed for lighter boats. It mounts along the keel line of the trailer (typically on adjustable brackets on the frame) and provides a rotating support that the boat’s keel can glide over during loading or launching. The white color indicates a non-marking material that won’t leave dark streaks on the bottom of your boat – this is especially important for boats with light-colored hulls or expensive anti-fouling paint.
With a diameter of about 7.5 cm and a length of ~7.8 cm, this roller is relatively small and intended for boats with lower draft and weight (for example: inflatable boats, dinghies, small fishing boats, jet skis). The 14 mm bore allows easy installation on a standard shaft or bolt; make sure the axles on your trailer are that size – 14 mm is a common standard on smaller trailers. The roller is made of a tough plastic polymer that withstands the keel’s impact and sustained pressure without significant deformation. The material is also UV-resistant, so it won’t become brittle or discolored from sun exposure, and it holds up in saltwater (it won’t swell or crack).
Practical advantages and use:
- Simplifies boat launching and retrieval: As the boat is pulled onto the trailer, the keel roller spins freely and reduces friction – meaning less force is required to move the boat and there’s less risk of hull damage
- Protects the boat and trailer frame: Instead of the keel grinding along metal beams, it contacts the smooth surface of the roller; this prevents wear on both the boat’s hull and the trailer’s paint/coating
- Suitable for multiple applications: In addition to the main keel line, these small rollers are often used as support rollers on side bunks or on specialized rigs for various equipment (for example, guiding pipes or cables on utility trailers)
- Easy installation and replacement: To replace a roller, simply remove the cotter pin or nut on the axle, slide off the old roller and put on the new one; this process takes only minutes with basic tools
- Recommendation: Inspect your rollers periodically – if you notice cracks, flat spots, or if they don’t spin freely, replace them in time. Cleaning off sand and marine growth regularly will also extend their life and ensure they roll smoothly
