3 inch x 5 inch x 26mm ID Red Ribbed Wobble Roller
Why are some wobble rollers cheap. Good question. The construction of wobble rollers vary from prime resin material to recycled resin material, some with UV and some without UV. A cheap wobble roller could have no UV resin and made from recycled drink bottles as opposed to a virgin resin and prime UV resistant resin.
So there is the difference why wobble roller prices vary. Wobble rollers made from non-virgin resins are likely to crack and fade are likely to fail prematurely.
The shaft for wobble rollers should be 3mm smaller than the ID of the wobble rollers.
There is no practical difference between ribbed wobble rollers and smooth wobble rollers other than personal preference.
Consideration should be given to two components for all boat rollers on your trailer.
- Vertical load capacity.
- Shock load horizontal capacity.
Vertical load capacity deals with a number of rollers per craft. Rule of thumb is, the more the better.
Horizontal impact capacity has never been a consideration however clearly, the shift away from 25mm solid stem to 40mm tube stem has a lot to do with horizontal impact.
Where ever possible, install 40mm tube brackets or larger.
