9-Blade Multiwing Z Hub Set, 1.5" Bore, No Bolt Pattern

Multiwing 9-blade Z-series hub set (hub plate and ring), flange mount, die-cast aluminum: 8.25" (209.6 mm) diameter with a 1.500" pilot bore and no bolt holes, ready to drill to your mount.

• 9 blade positions, Z-series
• 8.25" (209.6 mm) outside diameter
• 1.500" pilot bore, no bolt pattern (drill to suit)
• 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).

Building a fan

Add 9 fan blades (or fewer, with Multiwing blanking caps in the empty holes) and our Z-series cutting service.

Boring and bolt patterns

We can bore the center and drill your bolt pattern in our machine shop, so the hub bolts straight on. Add our hub boring and drilling service ($195.75 per hub) and put your bolt circle and hole count in the order notes. The 1.5" bore already matches the 38 mm pilot used on John Deere fan mounts.

Common engine patterns we drill: Cummins (4 bolts on 60 mm, 1" pilot); John Deere (4 bolts on 2.5" for 8 mm bolts, or 4 bolts on 2.875" for 10 mm bolts, both on a 38 mm / 1.5" pilot); Caterpillar C15 industrial (6 bolts on 100 mm, 50 mm bore); Detroit Diesel Series 60 (6 bolts on 3.5", 2.0" pilot). Tell us your engine in the order notes and we will confirm the hub can take it.
