TECHNICAL FEATURES BBB30
- Stainless steel ball bearing races, stainless steel ball bearings and glass fibre reinforced sheave for best bearing strength even under high dynamic loads.
- Acetal bearing cage to prevent ball-to-ball friction and to reduce weight.
- Glass fibre reinforced composite.

WHY CHOOSE BBB30
The BBB30 is the step up from the BBB20 and covers lines up to 8 mm. Use for control lines and purchase systems requiring higher loads and less friction. Use for 6mm sheets or 8mm sheets where a compact block is required. For larger line sizes BBB40 is the appropriate choice, for higher loads select BBB25.
