    Model numbers I8510-I8513 are designed and tested 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, a hardened precision ground alloy steel hinge pin of aircraft quality. The hinge pin is Armoloy® coated for additional corrosion protection and a lower coefficient of friction. Oil seals are provided to protect the hinge internals in more severe environments, while lubrication holes allow for periodic greasing.

    Note: recommended for any door (2000 lbs or less) specified with closers or handicap access because of lower Operating Torque. Due to installation variables, we are not responsible for meeting the 5 lb maximum force required by certain codes.

i-8500 Installation Instructions

N/A Series i-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, the minimum fillet weld size shall be 1/4", and be full length on the top, bottom, and vertical edges of the mounting surface of each hinge leaf. There shall be no welding on the backside, adjacent to the hinge barrel. Assure the weld interpass temperature at the hinge barrel 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.
