# What is the approximate expected life span of dimpled PTFE bearings?

## D.S. Brown can efficiently design, manufacture and test Versiflex™ high-load multi-rotational (Versiflex™ HLMR) pot and disc style, spherical and elastomeric bearing assemblies for all types of construction.

**Answer:** Many factors affect the service life of PTFE such as thickness, temperature, sliding speed, pressure, and whether or not a filler material is specified. “Design Guide for Bridges for Service Life,” a TRB publication, provides guidance on this subject and can be downloaded for free using the following link: [https://nap.nationalacademies.org/download/22617](https://nap.nationalacademies.org/login.php?record_id=22617)
