Stainless Steel Rollers
Non-magnetic and strong, for use under magnets and on conveyors carrying magnetic material: solid CNC-machined stainless steel bearing housings welded to standard-size stainless steel tube, with machined running surfaces and dynamic balancing.

Stainless steel tube and shaft.
Solid CNC-machined stainless steel bearing housings welded to standard-size stainless steel tube give Lorbrand stainless steel rollers their strength. Proprietary manufacturing techniques and equipment keep weld deformation to a minimum.
Housings, tube and shaft are all stainless steel. The non-magnetic construction suits use under magnets in heavy-duty applications, and the material also resists corrosion in wet, coastal, chemical and washdown environments.
Nothing moves, yields or creeps.
Five design features that determine bearing and roller life.
Precision bearing seats, constant tolerances
Solid machined housings hold constant bearing-seat tolerances throughout decades of service.
Welded housing-to-shell joint
The welded joint holds each housing in the shell, preventing the housing-to-shell failures that damage belt and frame.
Proven 4-stage sealing system
Centrifugal seal, labyrinth seal, storage seal and bearing seal work in series to keep contamination out and grease in, for maximum roller life.
Machined running surfaces, dynamically balanced
Running surfaces are machined and every roller is dynamically balanced, for smooth running at belt speed.
Concentrically machined & ground spindles
Stainless steel axle spindles are CNC-machined and ground concentric to the shaft, so the bearing runs true on its seat.
