7-Blade Multiwing Z Hub Set, 75mm Center, 5-Bolt Uniboss Mount

Multiwing 7-blade Z-series hub set, 7.7" (196.2 mm) diameter, with a 75 mm pilot and 5 bolts on a 90 mm circle, ready for a 5-bolt center boss. The center boss flange is the same for every bore type, so this hub takes an SH, P1 or other 5-bolt Uniboss. The center boss is sold separately.

• 7 blade positions, Z-series
• 7.7" (196.2 mm) outside diameter
• 75 mm pilot, 5 bolts on a 90 mm circle for the center boss
• Die-cast aluminum

Which blades fit

Takes Multiwing and Wing Fan Z-series blades, such as the 4Z, 5Z and 7Z, and the Wing Fan P4Z, P5Z and P6Z. Blades of the two brands fit the same hub, but they may not weigh the same, so use one brand per fan (or place them in opposite positions to keep the fan in balance).

Matching center boss

Multiwing P1 taper AS/BS or AR/BR, or the SH taper pull-through (reverse mount). Not sure which? Send a photo of your current fan.

Building a fan

Add 7 fan blades (or fewer, with Multiwing blanking caps in the empty holes), a center boss with its taper bushing, and our Z-series cutting service.
