Q: What advantage does polyurethane seal construction offer over rubber seals?
A: Polyurethane seals provide superior wear resistance and flexibility compared to standard rubber seals, extending bearing life in demanding warehouse conditions. They maintain seal integrity across a wider temperature range and resist contamination from moisture and abrasive dust. The pre-lubricated maintenance-free design means no field lubrication is required or possible.
