Viking 6in Self-Centring Blue Hard Nylon Roller – 17mm Bore (91330)

Aluminium boat or trailer rollers worn to nothing? This is the one. Hard nylon construction built specifically for aluminium hulls where you need a tough surface that won't mark or deform under load. Self-centring means it tracks straight on the shaft without constant adjustment after every launch. 17mm bore fits standard trailer shafts. No more wobbly, off-centre rollers scraping your hull on the ramp
