Machines and systems always require stability. To this end, parts’ specialist JW Winco has added two newly designed machine “feet” families to its portfolio.
For customers who have special threaded studs for their machines, JW Winco offers GN 36.1 and GN 37.1 as just the foot plate without stud.
In addition to providing high-quality and an exceptionally stable design, the components feature additional benefits. The new solid machine feet 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 and robust connection between the threaded stud and foot. The threaded stud is not connected to the foot plate. Instead, the stud centers itself 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. It also comes with a matching lock nut.
The forged steel foot plate is available in a diameter 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 11240 lbf (5 t) to 56202 lbf (25 t). The static load capacity for type B ranges from 4496 lbf (2 t) to 24729 lbf (11 t) due to the nature of the rubber pad.
The feet are ideal for use on uneven floors; however, the machine feet may not be used on a surface inclined at greater than three degrees to the threaded stud.
The second new machine foot GN 37 offers a central fastening hole running clear through. This allows use of an anchor bolt. The anchor secures 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 GN 37 can be ordered in types A, B, and C. The machine feet GN 37 of types A and C can support between 8992 lbf (4 t) and 33721 lbf (15 t), depending on diameter, and the load capacity of type B ranges between 4496 lbf (2 t) to 24729 lbf (11 t).
