[Features]
· Ideal for when a thin-wall hub design is desired.
· The outer diameter of the hub can be reduced by making the wall thinner.
· Can be used for overall short length hubs.
· Installation time is reduced by reducing the number of bolts.
· With short surface pressure section, the product is ideal for reducing the width of the hub.
