The G-Flex Bolt Set for FCL / FCLS is a bolt and bushing assembly designed for use with flexible flanged shaft couplings in industrial power transmission systems. It is commonly used in pumps, compressors, conveyors, wind and hydro machinery, and other rotating equipment applications.

Product Description
The bolt set consists of:
• High-strength bolts
• Washers
• Rubber bushings (NBR)

It is specifically engineered for FCL (Cast Iron) and FCLS (Carbon Steel) flexible flanged couplings. The assembly helps transmit torque while absorbing vibration, reducing noise, and compensating for shaft misalignment.

Key Features
• Simple and easy-to-install structure
• Rubber bushings absorb:
o vibration
o shock loads
o angular and parallel misalignment
• Bushings are replaceable without removing the full coupling
• Prevents transmission of thrust loads
• Available for multiple coupling sizes from F1-SET to F7-SET

Material
• Bolts/Nuts: Equivalent to SS400 steel with trivalent chromate treatment
• Bushings: NBR (Nitrile Rubber), hardness HS70
• Washers: SWRH62 steel

Typical Applications
• Pumps
• Fans and blowers
• Compressors
• Conveyors
• Industrial machinery
• Wind and hydro equipment
