an oil impregnated bronze bushing will provide permanent lubrication to carriage bolt rotation. Press-formed raceways in both Base and Rotor Bottom shall capture ball bearings and protect rotating components from excessive or unusual wear, burnishment and fatigue. All ball bearings shall be a minimum of s " 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-size shall require a minimum of 44 ball bearings. Raceways and ball bearings shall be dynamically and per- manently lubricated. Diameter of raceways shall be minimum 22" for letter-size and 28" for Legal/EDP-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 be applied to rotation surfaces of the Base and Rotor Bottom.
