SPIROL Receives 2025 Supplier Excellence Recognition Award from Caterpillar

Absorbing Centerline and Stack-Up Tolerances with Oval Compression Limiters
In assemblies with two or more fastening or joining points, Compression Limiters must align with the mating components and maintain a defined centerline tolerance relative to one another. As individual part tolerances stack-up, the risk of misalignment grows. SPIROL’s Oval Compression Limiters provide an effective solution for absorbing these stack-up tolerances while preserving proper centerline alignment.

How Pre-Fabricated Disc Spring Stacks Help Manufacturers Save Time, Money and Ensure Quality
One of the most demanding and complicated components to construct in a production environment is the Disc Spring Stack. When manufacturers use pre-fabricated Disc Spring Stacks rather than purchasing single Disc Springs and stacking them in-house, they are easily able to save time and money while ensuring the quality of their final assembly.

The Difference Between Coiled Spring Pins and Slotted Spring Pins
Thanks to their flexibility, not only are Spring Pins less expensive to manufacture, but the hole preparation is also less tedious and less expensive than Solid Pins. The comparatively lower stiffness also brings another benefit – Spring Pins do not damage the host hole (when properly selected) - so much so, that they can be serviced without the need of re-working the parts. In this White Paper learn about the primary differences between the two basic types of Spring Pins: Slotted Spring Pins and Coiled Spring Pins.

Performance Expectations for Threaded Inserts in Plastic Assemblies
Threaded Inserts enable designers to manufacture components out of plastic rather than metal to save cost and weight without sacrificing joint strength.  Learn what factors impact rotational torque and tensile performance of Inserts and how to assure a stable design.

How to Select the Proper Spacer for Your Assembly
There are many different types of components that are used as spacers, standoffs, or distance bushings. Learn the advantages of using Roll Formed Tubular Spacers over more expensive spacing options.

Solid Pin Retention Features
Solid Pins are commonly used as a permanent fastener in a wide range of applications. They are retained by the harder Solid Pin displacing material in the softer host component(s).  There are several types of Solid Pin retention features. This White Paper describes the common types of retention features and can serve as a reference tool when designing a new product.

How to Design the Proper Hole for Heat / Ultrasonic Inserts
This White Paper focuses on the recommended hole design for plastic assemblies that use Threaded Inserts installed by heat or ultrasonics to maximize performance.
