Product Overview


Designed With Adaptability In Mind
The Sta-Collar® is easy to install and enables fast operation of up to five assembly cycles per minute - as much as four times faster than currently available products. There are no pieces to pre-assemble - just simple automated clamping and spot-welding processes that adapt easily onto your line. The entire assembly takes place before the finish is applied, further simplifying the process. Its design allows positioning within tighter tolerances for more precise placement on the bar. Overall, its design and adaptability provide a cost-effective solution.

The Sta-Collar® provides superior push-off capability, consistently exceeding 300-1300 pounds, dependent on design and application. The one-piece design offers long life durability and strength.
  Extruded
When high push-off performance is required. Your Sta-Collar® can be engineered to satisfy clearance requirements.

Non-Extruded
Suited for applications on smaller bar diameters under 20mm, and where clearance or high push-off performance are not driving factors.

In testing the Sta-Collar® we have made the following observations:

Surface Finish
  Peel or blast finished stabilizer bars achieve higher push-off values compared to smooth finished bars.
  Smooth finished stabilizer bars provide better-controlled diameter tolerance and more consistent push-off performance when compared to the rougher finished bars.

(Note: The Sta-Collar® is engineered to provide push-off performance well above requirements, thus negating resultant fluctuation attributed to surface finish.)

Temperature Variation
  Testing performed on the Sta-Collar® assembled on stabilizer bar pieces showed no reduction in push-off performance when subjected to temperatures of +70°C to -40°C.

Cycle Testing
  Cycle testing performed on specific platform suspension systems by Sta-Collar® customers has showed no failure.
  No on-vehicle failures have been reported during road testing or after sale.

The Sta-Collar® offers two basic design alternatives to fulfill your project's requirement. The clamping process - vital to the performance of the Sta-Collar® and all its tooling was developed by engineers at Waukesha Tool & Stamping. Our team of design engineers will assist you in determining the precise design that suits your specific application requirements.
