Lock Plates
When your thrust washers, shims and other metals stampings require a form of anti-rotation, this is known as a lock plate. At Northern Industrial we have been producing lock plates for differentials and other automotive applications for many years. While there are many benefits we can offer for your high volume production lock plates, the core of our product line is enhanced tolerances, low cost high volume manufacturing and vertical integration. The enhanced tolerances we can offer are:
- Flatness: 0.001 inches (0.025 mm)
- Parallelism: 0 .001 inches (0.025 mm)
- Thickness: +/- 0.0004 inches (0.010 mm)
- Surface Finish: 0.25 Micro Meter (10 micro inches)
In addition to providing enhancements to the tolerances of our product, Northern Industrial Manufacturing also offers our customers a wide variety of secondary operations that can be performed on the part. Those options are:
- Color Code Identification
- Heat Treatment
- Coating
- Plating
- Heat Set
If your application requires lock plates, Northern Industrial Manufacturing can supply your high volume production assembly lines.
