Spyraflo low-friction needle bearings were the design secret to a new, fully-automated paper-folding machine capable of folding 18,000 sheets of paper per hour. Mounted directly into the machine’s sheet metal chassis, the self-aligning, self-clinching roller bearings not only eliminate the need for rigid, accurately machined mounting blocks, they also allow the use of less expensive drive motors.

On the new design conventional plain bearings did not prove suitable because they have some shaft resistance to turning and typically overloaded the new drive. While low-friction needle bearings worked better, the machine’s thin sheet metal framework also demanded a self-aligning bearing to compensate for dynamic misalignment generated by the drive.

The simple solution was the easy-to-install bearing unit called ReadyMount, the result of a partnership between Spyraflo and INA. The design utilises a Spyroflo full-contact, self-aligning insert to support an INA needle roller bearing. This assembly, in turn, is housed in a Spyraflo retainer, permitting secure installation into sheet metal.
