So what are your bearing choices for a wet environment application? Polyesters and Acetron materials hold up well. And our marine clients have done extremely well with Ultracomp for their rudder bearings, since they are durable and excel in linear, oscillating and rotary applications. Our CJ product line is another good choice, since they remain dimensionally stable in liquid. No matter what material you choose, we recommend that you avoid graphite, because it gives a cathodic charge in saltwater.
Very few PTFE-based materials excel in water, but we can help you find the right one for you freshwater, saltwater, DI, or chemical blend submerged applications.
