Neptonics Roller Wheels

Neptonics Roller Wheels

These Rollers are the ones we use for our spearguns. They are very strong, made from Delrin. The standard has no bearings, and are made in two sizes; one for 9/16th-5/8th (14mm-16mm) rubber and one for 3/4in (18mm) rubber. The ball bearing roller easily accepts 9/16 (14mm) and 5/8 (16mm) powerbands. They are sold individually.
