HUB DETAILS PUFLEX GS hubs are available in Aluminium and Steel Material. PUFLEX GS sizes from 9 to 38 are made from Aluminium Alloy material. PUFLEX GS sizes from 42 to 65 are made from Steel. PUFLEX GS hubs are manufactured with high precision machining. The jaws are machined with concave shape and entry chamfer for easy assembly. The concave shape in jaws of hub and the convex shape on the polyurethane spider allows for better angular, parallel and axial misalignment. These hubs are available in un-bored, pilot bored, finish bore & key-ways, and with different styles of clamping arrangements as per customer requirements.
