# What is the largest bearing D.S. Brown can test?
## Versiflex™ elastomeric bearing assemblies are custom molded using neoprene or natural rubber and are categorized into three basic designs: non-reinforced, laminated and sliding bearing assemblies.
**Answer:** The largest bearing D.S. Brown can test is 700 kips horizontal and 6800 kips vertical. Other third-party facilities like [University of California, San Diego](https://ucsd.edu/) (UCSD) or [National Institute of Standards and Technology](https://www.nist.gov/) (NIST) can test larger loads.
### **Learn more about D.S. Brown Structural Bearing Assemblies**
Since 1963, The D.S. Brown Company has provided [structural bearing assemblies](https://www.dsbrown.com/product-category/bridges/structural-bearing-assemblies-2/) and joint seals for bridges around the globe. Bridges and other large structures are supported on bearing assemblies to transmit forces while accommodating all structural movements.
The selection of an appropriate bearing assembly is based on the magnitude of vertical and horizontal forces transmitted through the bearing assembly, as well as the amount of displacement and rotation of the superstructure elements. In addition, special attention to the bearing assembly design may be necessary when, for example, larger than normal horizontal loading or uplift situations exist.
