Suitable Applications
- The 91211 is designed for keel and centreline support positions on boat trailers. Its black rubber construction provides softer contact than the hard blue nylon rollers and can be used where a conventional rubber keel roller is required.
Signs the Roller Needs Replacing
- Replace the roller if the rubber becomes cracked, split, hardened, flattened or deeply grooved, or if the centre bore becomes elongated. Excessive sideways movement or poor rotation can also indicate wear. Check the spindle at the same time for corrosion, bending and wear grooves.
