The 91332 8" Blue Nylon Self-Centring Roller is a hard-wearing boat trailer roller designed to support the keel while helping guide the boat towards the trailer centreline during retrieval. Featuring a nominal 203mm / 8" width and 21mm bore, its hard blue nylon/poly construction provides excellent wear resistance. The self-centring profile is particularly suited to aluminium and alloy boat hulls.

Self-Centring Design
- Unlike a conventional straight keel roller, the 91332 has a self-centring profile designed to encourage the keel towards the centre of the roller as the boat is retrieved.
- This helps improve alignment with the trailer's centreline, particularly when approaching the trailer slightly off-centre.
Suitable Applications
- The 91332 is suitable for boat trailer keel and centreline roller positions, particularly where a self-aligning roller is desirable during retrieval. The hard blue nylon/poly construction is commonly used for aluminium and alloy boats, where durability and abrasion resistance are important.
Signs the Roller Needs Replacing
- Replace the roller when the hard poly/nylon becomes cracked, chipped, heavily grooved, distorted or excessively worn. An enlarged centre bore, excessive sideways movement or poor rotation can also indicate wear. Check the spindle simultaneously for corrosion, bending and wear grooves.
