Where it earns its place
Best-Fit Uses
Stepped housings and shaped pockets
Fits around shoulders or changing bore sections that would interfere with a straight-sided coil.
Staged closing behavior
Allows sections of the spring to come into contact at different points in the stroke when that behavior is intentional.
Push-back after a linear movement
Useful when a part is pressed inward and needs to return along the same axis after the load is removed.
Maintaining contact between stacked parts
Helps keep two parts touching when normal movement or tolerance would otherwise create a gap.
Why this style works here
What This Spring Style Solves
A tower profile follows a stepped envelope rather than a simple straight taper, making it useful when the spring must clear shoulders, bosses or changing pocket diameters.
Before you choose it
What to Confirm in Your Assembly
- Send a section view or 3D model of the spring pocket, including every shoulder and diameter change.
- Mark the installed and fully compressed positions so local coil clearance can be checked.
- Give the installed height and the shortest height the spring can reach in service.
- Show any guide pin, bore or nearby wall that controls where the spring can move.
- State the required force at one or more working positions, not only a free length.
Avoid forcing the wrong spring into the design
When Another Spring Style May Fit Better
A tower shape adds complexity and should solve a clear packaging or staged-contact problem. If the pocket is a simple cylinder, a cylindrical or conical spring is usually easier to control.
- Variable-diameter compression springs for smoother envelope changes
- Conical compression springs for a simple taper
- Cylindrical compression springs for uniform pockets

Environment & Material Direction
Choose corrosion and temperature resistance after the required load, movement and available space are clear. The Materials section is the right place to compare alloys; this page stays focused on how the spring works in the assembly.
For the material families represented in this product's reference configurations, compare Carbon & Alloy Spring Steels, Stainless Steel Spring Materials, Copper Alloy Spring Materials, Nickel & High-Temperature Spring Alloys. Confirm the exact grade and condition for your assembly.

Application questions
Frequently Asked Questions
Is a tower spring the same as a conical spring?
Not necessarily. A conical spring usually changes diameter continuously, while a tower spring can use distinct steps or sections to fit a shaped pocket or create staged contact.
When should I consider a different compression-spring style?
If compressed height is extremely limited, the pocket changes diameter, or the required force must be produced over very short travel, a conical, wave or disc-style spring may package the job more efficiently.
What should I send for an application review?
Send the assembly drawing or a clear sketch, the working positions, the force or torque you need, expected cycles, environment and quantity. If an existing spring is being replaced, include its dimensions and explain what is not working well in the current design.
