Еrmes roller pulleys with slifing rolls D28xH16 (pair)

Pair of straight roller speargun pulleys made entirely of Derlin and with sliding rolls. These pulleys are designed to withstand high working loads. The channel is designed to prevents the sliding of the bands within the pulleys during the contraction phase, which is one of the main reasons for the instability of the shot. 

Dimensions:

• Shaft: 6 mm.
• Large diameter: 28 mm.
• Small diameter: 16 mm.
• Channel: 19 mm. 
• Weight: 18 g.

To prolong the life of the pulleys, please rinse and soak in fresh water after each use to clean sand and dirt and allow dispersion of the salt crystals.
