Door Hardware Sliding Rollers

End Adjust

End Adjust Tandem Rollers are equipped with full race, permanently lubricated radial ball bearings that are labyrinth-shielded to protect from dust and moisture. Ball bearings are manufactured to provide the highest quality assemblies. End Adjust Tandem Rollers can support doors up to 350 lbs. End Adjust Tandem Patio Door Rollers offer a unique advantage in that we manufacture our own ball bearings. This allows us complete control over all aspects of design and production of our roller assemblies. While others may use soft stamped metal parts in the production of their wheels, our bearing raceways are machined from solid steel bar stock and then heat treated for wear resistance and plated for corrosion resistance. This method provides the longest lasting, true running rollers capable of carrying the heaviest loads.
