UniqueTek Dillon 550 Primer Track Bearing
By UniqueTek, Inc.
The UniqueTek 550 Primer Track Bearing has a 1.4″ extension that supports the primer bar better. This extended support prevents the primer bar from "drooping" and binding while its in the "out" position. The top surface of the bearing has also been coated with a Molybdenum Disulfide dry-film lubricant to further enhance smooth motion of the primer bar.

The UniqueTek 550 Primer Track Bearing is a drop-in replacement for the original Dillon Primer Track Bearing (part #14015) and takes just minutes to install.
