Difference Between Rocker-Rollers and Wobble Rollers for Boat Trailer

Question:

Whats the difference between wobble rollers and rocker rollers? It looks like the # DL21562 and the # YR440R are the same construction, but they have different names. The # DL21564 one looks like different construction also... Please elaborate. Thanks

At one time, wobble roller was a patented term, but now the term wobble roller and rocker-roller are interchangeable. The # DL21564 roller you mentioned has an integrated bushing that makes the roller track straight on the shaft it's installed on, while the other two rollers lack this bushing. Not only would these rollers be capable of rotating on the shaft, they'd also wobble as well. The key would be to determine which style your boat trailer uses and use the appropriate replacement.
