Variable force springs are used in point-of-purchase (POP) retail displays with slide trays to push products to the front of a machine or shelf for easy customer access. While they’re similar to constant force springs, variable force springs deliver varied levels of force to accurately match increasing or decreasing product supply levels.

Benefits of PUSHER Variable Force Springs
Variable force springs are used to push products forward in a display. They apply greater force in the full display position and less force as products are removed. This design provides many benefits for retailers, including:
- Cost Efficiency: Variable force springs consistently position products at the front of the shelf, eliminating the need for employees to do these tasks. By using variable force springs and vertical displays, retailers can also save floor space and optimize product layout throughout the store.
- Control: Since various levels of force are applied depending on the amount of products in the display, variable force springs allow for better control and ease of use when products are removed from the shelf.
- Product Integrity: Variable force springs operate based on the weight of the products they are pushing. This ensures the product never gets damaged due to too much force.

PUSHER Variable Force Spring Applications
The main uses of variable force springs are point-of-purchase pusher applications where products must be pushed to the front of a machine or shelf. Most POP pusher applications rely on these springs’ ability to accommodate different loads at different positions to push the products forward.
Because they provide a varying amount of force based on the amount of deflection, variable force springs are ideal for horizontal displays like pusher trays or vertical displays in which products must be up-fed. Variable force springs can support a wide range of product weights, from lightweight video games and cosmetics to heavy cases of soda bottles.
