Enjoy the many benefits that our revolutionary AirForm® process brings to rollers and pulleys. It is a CNC controlled process that selectively reduces the tube diameter along its entire length. AirForm® rollers and pulleys are true precision grade with TIR’s that range from .020″ to .010″ – not the .060″ to .120″ associated with expanded rim technologies. Also, AirForm® rollers and pulleys are available in point, trapezoidal, arc, concave, and straight crowns. Like our machined grade rollers and pulleys, AirForm® components are available in all shaft to pulley configuration, with or without lagging, and can be dynamically balanced.
Eliminate the additional expense and weight required to machine rollers and pulleys – with AirForm® you get a lighter weight pulley without all of the extra fabrication and material costs.
- Rollers and pulleys manufactured with Bryant Products’ revolutionary AirForm® technology require no tooling
- Available in major diameters ranging from 1.50″ to 9″, lengths up to 82″, and wall thicknesses to .250″
- Bryant manufactures the most accurate tapers in the industry with TIRs down to .010″
- Available in low carbon, stainless steel, and aluminum
- Since our tubes are free-formed in air, you can specify a wide range of concave, convex, compound, wave forms, cylindrical shapes with single or multiple crowns or grooves, and back-to-back taper designs
- Optional unique, single piece “drop-back” design eliminates the cost, weight, additional material, welding, and reduced TIR common to “True Taper” rollers using washer in the back end for a bearing set
- The drive grooves in our belt driven rollers are produced during the basic forming operation, thereby eliminating the expense of a secondary operation.
- For extraordinary savings, use AirForm ‘V’ guide pulleys for belts equipped with ‘A’ or ‘B’ section tracking guides. WIth AirForm® ‘V’ guide pulleys, the relief groove is precision formed directly into the face of the pulley. This completely eliminates all of the fabricating needed to mate a machined center section to the butt welded barrel sections along with the subsequent machining of the welded components.
The economies associated with AirForm® parts are these:
- All machined trapezoids and crowned pulleys or cores have to start out with heavy wall tubing to allow for the removal of mataerial. Since AirForm® reduces the diameter of the tubing, rather than cut it away, conveyor pulleys and cores for various industrial rolls can be formed from lighter gauge materials.
- The cycle time to AirForm® a part is 75% less than that of a lathe turned core or pulley without any sacrifice in run out or balance. In fact, the lighter mass of AirForm® shells often has a beneficial effect on the life of supporting members.
