APS - Orbit Blocks - Series 40, Ball Bearing (BB)**ND**

Orbit Blocks - Series 40, Ball Bearing (BB)

Ronstan’s proven ‘two-stage’ bearing system enhances durability and low friction performance across the full working load range. The Dyneema® link provides a more flexible, lighter weight and lower profile solution than traditional shackles. It is also more compatible with Dyneema®/Spectra® strops, webbing and carbon connection points than steel loop tops or shackles. Can be set at 0 or 90o orientation, provides stress free articulation with no over-rotation and a security clip locks it in place. Suitable for sheet applications on dinghies, sportsboats and small one-design keel boats, vang and backstay applications on boats to 9m (30’), and control lines on larger boats.

Applications:
- Mainsheet and Spinnaker sheets on dinghies, sportsboats and small keel boats to 9m (30ft).
- Halyard, Vang and Backstay applications on boats to 8m (26ft).

Materials:
Sheave: Carbon fiber reinforced, PTFE & silicon impregnated Nylon
Ball Bearings: High compression strength carbon black Acetal
Stage 2 Bearing: Carbon fiber reinforced, PTFE impregnated Nylon
Housing/Cheeks: Toughened, glass fiber reinforced Nylon
Rope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®
