Leveling Machine Feet for Heavy Machines (GN 36/GN 37)
Description
Two solid machine feet families have been added to J.W. Winco's portfolio and are particularly well suited for large and heavy systems and machines.
The machine foot GN 36 uses the weight of the machine to create a stable connection between the threaded stud and the foot. The threaded stud is not connected to the foot plate; instead, the stud centers itself automatically at the contact point via the radius.
The blue zinc-plated steel threaded stud is available with fine thread from M20x1.5 to M42x2 for precise leveling and comes with the matching lock nut. The forged steel foot plate is available in diameters up to 7.87 in. (200 mm), has a powder-coated black matte surface, and can be ordered in three different types:
- With Type A, the foot plate rests flat on the underlying surface.
- Type B has an NBR rubber pad that reduces wear on the surface beneath and is also suitable for contact with oil or coolants.
- Type C has an O-ring that seals the foot plate, preventing liquids from penetrating under the foot.
Depending on the foot plate diameter, types A and C can each support a load of 1,1240 to 56,202 lbf (5 to 25 t). The static load capacity for type B ranges from 4,496 to 24,729 lbf (2 to 11 t) due to the nature of the rubber pad. The feet are suited to compensating for an uneven floor; however, they may not be used on a surface inclined at greater than 3-deg. to the threaded stud.
The second machine foot, GN 37, also has a central fastening hole running clear through which allows the use of an anchor bolt to secure the foot to the floor, preparing it for lateral loads. This makes the machine feet optimal for manufacturing systems or conveyors that are subjected to dynamic movements and lateral forces due to the use of robots. As with GN 36, the foot plate on GN 37 can be ordered in types A, B, and C. Types A and C can support between 8,992 and 33,721 lbf (4 to 15 t), depending on the diameter, while the load capacity of type B ranges between 4,496 to 24,729 lbf (2 to 11 t).
For customers who already have special threaded studs for their machines, Winco offers GN 36.1 and GN 37.1 as just the foot plate without studs.
