The 91563 8" Red Poly Keel Roller with Alloy Centre is a heavy-duty boat trailer roller designed for increased strength, keel support and smooth launching and retrieval. Measuring 203mm wide with a 17mm centre bore, it combines a rigid aluminium centre with a softer red polyurethane outer. The non-marking, UV-stable poly surface protects and guides the keel, while the reinforced alloy centre supports loads of up to 600kg per roller.

Suitable Applications
- The 91563 is designed for boat trailer keel and centreline support positions, particularly where a reinforced roller is required. The aluminium centre adds strength and keeps the roller rigid, while the softer red polyurethane outer provides a non-marking contact surface that supports and guides the keel.
Signs the Roller Needs Replacing
- Replace the roller if the polyurethane becomes deeply grooved, cracked, split, distorted or excessively worn, or if the roller becomes seized or develops excessive movement around the spindle. Also inspect the alloy centre and 16mm spindle for corrosion, deformation and wear before fitting the replacement.
