For use on security doors, cell doors and personnel gates used in the detention industry. Also heavy architectural gates, lead filled radiation doors, vault doors and door applications where the hinges will be subjected to severe loads from a blast pressure, seismic event or high wind velocities.

The barrel and leaf sections of the hinge are fabricated from 1018 cold rolled steel and joined with welds of x-ray quality. The CBI-8500 is then machined to precise tolerances; allowing precision bearings and hinge pin components to be used which significantly reduce wear and friction. The results: a reliable hinge that will allow doors weighing several hundred pounds to be operated by the touch of a finger.

The SERIES CBI-8500 comes in two capacities:

Model numbers CBI-8505 through CBI-8508 have been designed and tested to support thrust loads or doors weighing up to 800 pounds. For those detention grade applications, they meet or exceed ASTM F1758 Grade 1 and are FBOP approved.

They feature self-lubricating, maintenance free, radial and thrust bearings which have PV ratings as high as 28000 psi x fpm. A precision, ground stainless steel, maximum security hinge pin is welded in place. Model numbers CBI-8510 through CBI-8513 are rated for thrust loads or doors weighing up to 2000 pounds. They feature anti-friction needle roller bearings to transfer the higher radial and thrust loads and a hardened, precision ground, alloy steel pin. The hinge pin is also Armoloy® coated for additional corrosion protection.

To improve corrosion protection on all CBI-8500 models, we offer zinc plating or fabrication in stainless steel as an option. Oil seals are provided to protect the hinge internals in more severe environments while lubrication holes allow for periodic greasing.

When ordering: specify with or without mounting holes and type of standard offset.

Series CBI-8500 hinges can also be supplied with the following modifications: custom mounting hole layouts, shorter or longer hinge leafs and custom offsets. see detailed drawings technical data

Series CBI-8500 hinges will function at the rated capacities providing the following specification is met:

1. The hinges are installed without inducing "hinge bind".
2. A minimum of 2 hinges (1 pair) are used per door.
3. Door weight or thrust load shall never exceed the thrust capacity of one hinge.
4. Compliance with bolting specification.
5. Minimum thread engagement into reinforcing member shall be equal to bolt diameter.
6. For weld on applications, a minimum fillet weld size of 1/4" shall be installed on (3) sides of each hinge leaf. For the I-8505 through I-8508 models, assure the weld interpass temperature of the hinge does not exceed 225 deg. F.
7. For certain high frequency applications, adequate load distribution between hinges maybe necessary to obtain the highest margin of safety with respect to load-life on bearings.
