This bearing set consists of 18 rods and 2 cages (pin holders). This unit as a whole is responsible for the wheel’s smooth spinning process on 50 mm / 2 in axles. It is completely corrosion protected and resistant to sand and saltwater, therefore guaranteeing a maximum lifespan. Due to the fact that the rods themselves are spinning the friction inside the wheel bearing is extremely small adding even more years to the bearing’s lifespan. Furthermore the muscle power that is needed to launch your boat onto the trolley is greatly reduced.

This roller bearing is patented and made of high quality plastic material. Once mounted onto the axle one bearing unit supports weights up to 500 kg / 1100 lbs! This fact was scientifically proven by the advanced technical college in Kiel.

One bearing unit = 18 rods + 2 cages = bearing for one wheel. You will need collars (wheel fixations) to hold the wheel in place. We offer two different kinds, just click on the pictures below.
