SilverbackHD GeoMetric Series S-Cams Provide Tighter Tolerances For Longer Life, Better Braking
SilverbackHD’s GeoMetric Series S-Cams have become an integral component to the company’s Intentional Engineering® strategy of making every braking component not only tougher, but better able to harmonize with other braking components and minimize the maintenance cost to fleets.

Some of the unique features of SilverbackHD’s GeoMetric Series S-Cams include:

* Higher grade steels

* High Energy Rate Forging (HERF)

* Precision cut S-Cam heads and splines

* Uniformed heat treating

* Stone ground journals

A leading cause of premature brake failure, and unbalanced braking occurs from premature cam wear. SilverbackHD has dedicated itself to using a high standards of tool grade steel for the journal and cam heads. This high grade steel is necessary to withstand harsh cold conditions found in the Canadian north, and is proven to last longer in more even tempered road conditions.

After the cam head has been HERF forged, it is then precision cut at both the spline and cam end. Cam heads that are not precision milled can have a variance of up to .050 inch between cams, causing unbalanced braking and uneven brake wear.

After the cam and spline have been milled, they are then heat-treated to over 1,000° F until they achieve an OE standard hardness of HRC60. This hardness is Intentionally Engineered to match the cam end hardness on SilverbackHD GeoMetric new lined shoes, and the cam roller hardness on SilverbackHD’s GeoMetric Series cam rollers. This process of Intentional Engineering® reduces component wear and maximizes brake efficiency.

To perfect the S-Cams, each journal is stone ground to a fine RA16 finish to minimize wear on the cam bushing.

For optimum performance SilverbackHD GeoMetric Series cam repair kits are built to the tightest tolerances in the industry.

SilverbackHD’s GeoMetric Series S-cams are proven to endure the harshest conditions and last longer in more moderate road environs. Because at SilverbackHD Products, HD means “Heavier Duty.”
