Bearing Testing
To ensure product quality is met, our engineering teams do extensive and rigorous testing in our in-house testing facility. This ensures that the best products are developed for our customers, through extensive abrasion testing, heavy-wear testing and field testing. There are more than 15,000 laboratory tests done on US Synthetic PDC technology every year.
Bearing TestingPCD Development
As a result of our ongoing research and development efforts, US Synthetic bearings are better able to handle the demanding environments they work in, such as downhole motors, turbines, drilling tools, pumps or heavy equipment. From diamond powder to the finishing phase, every possible aspect of bearing development is monitored, measured and improved.

Our bearings use custom-made diamond inserts that are designed and tested to meet the specific needs of our customers. At US Synthetic Bearings division, we are committed to delivering the best parts now and continuing to innovate in the future to ensure success for our customers in their demanding applications.
To ensure that our bearings deliver the needed performance, we
subject the PCD component to the following tests:
- PCD Testing and Evaluation
- Vertical Turret Lathe Abrasion Testing
- Drilling Testing
- Impact Testing
pcd testing and evaluation
Our engineers put our bearings under rigorous testing to ensure they meet the needs of our customers. This includes extensive impact and heavy wear testing in our state-of-the-art testing facility, as well as extensive downhole testing in the field. As a result, US Synthetic bearings and diamond inserts have gained a reputation, built and maintained over many years, for superior quality, durability, and performance.
Vertical turret lathe abrasion testing
The Vertical Turret Lathe (VTL) test evaluates the performance of PDC abrasion resistance. Granite is machined at high speeds to load the cutter mechanically and thermally. Volume of rock removed is compared to the volume of diamond wear. From this comparison, a grinding ratio is calculated that allows the abrasion resistance of various cutters to be compared.
drilling testing
The drill rig evaluates the performance of a cutter in a drilling environment. Test cutters are brazed to a cirica 3-inch diameter test bit. The bit is advanced through various rocks at constant rates and the resulting torque and weight-on-bit is measured.
impact testing
The drop impact test evaluates the impact strength of the diamond inserts used in our bearings. This test emulates the type of loading that might be experienced when a bearing is subjected to lateral and/or axial vibrations.
