What are the differences between metal bearings and plastic bearings?

Metal bearings normally require lubricants like grease or oil in order to avoid seizure and rust. Plastic bearings, on the other hand, have a self-lubrication property and hardly get seizure or rust.

Is it OK to use metal bearings in the water?  Of course not.  Lubricants are washed away and metal bearings get rust in the water.

Plastic bearings do not require any lubricants, so you do not have to worry about de-lubrication.  In fact, water plays a role as a lubricant for plastic bearings. 

Not needing lubrication is just one of the benefits plastic bearings have. To find out more of the advantages of plastic bearings, please check our website here and here!
