Precision Pulley & Idler (PPI) enhanced its herringbone wing (HBW) pulley offering, reintroducing it in two styles: plate constructed and round contact bar.
According to PPI, the new plate-constructed line replaces its CEMA herringbone wing. The round contact bar style remains unchanged with the same availability.
PPI says the expanded size range of the plate-constructed herringbone wing allows the pulleys to be utilized in a broader range of applications.
In addition to the expanded size offering, PPI reengineered the top arc of the wings to improve the interaction with the face of the pulley as it makes contact with the belt. Also, PPI increased wing quantities in certain sizes to provide better belt support.
“PPI’s engineering team has really listened to the market feedback when making the design enhancements to this product line,” says Mike Roozeboom, industry product manager at PPI. “It’s due to these significant improvements and upgrades that we can expand the offering and retire the moniker ‘CEMA HBW.’ We no longer want this plate-constructed HBW style to be pigeonholed into a light-duty application with a limited size range.
“When our customers have a need for a herringbone wing, we want them thinking plate constructed,” Roozeboom adds.
PPI’s plate-constructed herringbone wings are offered in diameters of 6 in. to 60 in. and face widths of 12 in. to 78 in.
