Boat Trailer 2½” Black Tapered Roller – 17mm Bore, 85 Duro Rubber (SKU: TCBK2.5)

Boat Trailer 2½” Black Tapered Roller – 17mm Bore, 85 Duro Rubber (SKU: TCBK2.5)

This 2½-inch tapered roller is crafted from high-strength black rubber with an 85 DURO rating for firm, reliable keel support. Its tapered shape helps guide your boat smoothly onto the trailer while reducing resistance and bounce.

Fitted with a 17mm bore, it offers a loose fit on standard 16mm shafts, allowing the roller to turn freely on the shaft. This design reduces wear and friction, making it ideal for light to mid-sized boat trailers that require easy keel alignment.

Designed for Smooth Loading

The tapered profile helps self-align the boat’s keel during retrieval, improving trailer centring and reducing misalignment damage. Great for replacing worn rollers or building a custom roller cradle system.

Note: This roller has a loose fit on 16mm shafts – it is intended to spin freely for reduced friction and better wear performance.

Frequently Asked Questions

• Q: Is this compatible with a 16mm shaft?
  A: Yes – it has a 17mm bore and is designed to fit loosely on 16mm shafts.
• Q: What does “tapered” mean in this context?
  A: Tapered means the roller has a narrower middle, which helps self-centre your boat’s keel during loading.
• Q: Will this roller mark my hull?
  A: It’s made from black rubber, so on light-coloured hulls it may leave marks over time. For non-marking options, check out grey or poly rollers.
• Q: How firm is the rubber?
  A: It’s 85 DURO – quite firm and durable, ideal for structural support.

Not recommended if you:

• You want a non-marking roller for white hulls
• Your trailer requires larger diameter or longer rollers
• You prefer tight shaft fit (this is designed to spin freely)
