2.3 MANUFACTURED COMPONENTS
A. Rotary Unit Base:
1. Base and rotor bottom assembly will be constructed of 12 GA or greater drawing quality cold rolled steel.
2. Base and rotor bottom are to be connected with a minimum 2 inch (51 mm) diameter carriage bolt. A locknut shall secure assembly and an oil impregnated bronze bushing will provide permanent lubrication to carriage bolt rotation.
3. Press-formed raceways in both base and rotor bottom will be designed to capture ball bearings and protect rotating components from excessive or unusual wear, etching of any sort, and/or fatigue. All ball bearings shall be a minimum of 5/8 inch (16 mm) diameter, fabricated from high carbon steel and maintained at equal spacing with a flanged ball cage. Letter-size units shall use a minimum of 22 ball bearings; Legal/EDP/A4-size shall require a minimum of 44 ball bearings. Raceways and ball bearings shall be dynamically and permanently lubricated. Diameter of raceways shall be minimum 22 inches (559 mm) for letter-size and 28 inches (711 mm) for Legal/EDP/A4-size units. Smaller diameter raceways shall not be acceptable due to their inability to provide stability of unit during unbalanced loading and/or rotation. No heat (welds) shall ever or in any way be applied to rotation surfaces of the base and rotor bottom.
4. Springs included in base design shall be capable of stopping a fully loaded unit without requiring tension adjustment at any time. Operator assistance shall not be required to initiate a position stop of the rotating cabinet. Upon free-wheeling lock-out mode, operator shall be able to free spin the interior rotating cabinet without encumbrance of detents or other mechanically generated resistance.
5. Rotor bottom shall have functional storage shelf integrated into its design.
6. Four independently adjustable leveler glides shall be provided to allow for proper leveling of units. Any anchoring required by state, local and national codes shall be accomplished by securing cabinets to the floor with manufacturer provided anchoring system. Wall anchoring shall not be acceptable.
7. Separate bases shall be available for Starter, Add-on, and Extended add-on units and such bases shall be secured to each other to eliminate racking of units during rotation.
8. When indicated initially, special starter base units will be supplied to accommodate the future addition of units on either the right or left side. This provides growth flexibility as needs evolve.
B. Positive Position Control (Foot Pedal):
1. A positive position control system shall be utilized with each cabinet, delivering complete operator control of a spring loaded automatic self-centering mechanism. A simple detent positioning system shall not be acceptable.
2. Foot pedal shall be spring loaded and automatically return to its proper position.
3. Dual foot pedal option shall be available to allow access to the cabinet from both sides. Foot pedal shall be one-piece cast aluminum designed to prevent pedal failure as well as slippage of operator’s foot during operation. Rubber or vinyl coverings are unacceptable as they can wear or become loose over time.
4. An optional hand control shall be available which is used in place of the foot control pedal. The hand control shall be positioned within ADA reach guidelines and provide for complete operator control of the spring loaded automatic self-centering rotary mechanism.
C. Doors, Center Panel and Rotor Top:

Manufacturer shall have access to these and be able to provide them as an additional cost option upon request. Inner door shall be slotted (louvered) in 1-3/4 inch (44 mm) increments to allow for flexibility in shelf placement and for the acceptance of accessories required to house a wide array of media. Outer and inner door panels shall be welded together.
b) Center panel shall be triple-flanged to connect to the inner doors and rotor bottom. The door to center panel connection shall be made with dedicated fasteners at the inner door and rotor bottom. Length of fastener shall be engineered as such to not contact outer door during installation. Center panel to door fasteners shall be spaced no more than 12 inches (305 mm) on center.
c) Rotor top shall snap and lock into place with no visible fasteners. Rotor top shall include an oil-impregnated bronze bushing allowing permanent stabilization and lubrication of cabinet.
2. An option for pass through shelves shall be available when specified to accommodate rolled drawings, maps, or other oversize media. The pass through opening may be up to 12 louvers or 21 inches (533 mm) in height.
D. Reverse Beveled Posts, Vinyl Door Strips and Locks:
1. Reverse beveled posts, vinyl door strips and locks shall complement the appearance of the unit and be integrated into the unit.
a) Vinyl door strips shall integrate into the posts without the use of fasteners and be available in matching and/or complementary colors.
b) Posts shall function for either starter or add-on units.
c) Locks shall be included as standard equipment on all starters and adders, and available for multiple unit installations as either keyed alike or different. Locks operation may be upgradeable (at additional cost to be determined per project) to a security application suited to meet a predefined specific purpose. These shall be available and quoted by the manufacture on per job/per need basis.
2. Lock mechanism must interface with foot pedal to enable and maintain a free spin of base and rotor bottom in consideration for ADA Compliance.
E. End Panels:
1. End panels shall attach to either starter or add-on unit as may be required by configuration of units.
