Questions about this item

Will the set-screw on the 1/2 in bore hub need periodic re-torquing?

The 1/4-20 UNC 2B set-screw should be checked after initial run-in and at scheduled maintenance intervals to maintain clamping force on the shaft.

At 14,000 RPM what limits continuous operation first?

The 14,000 RPM rating is the maximum speed; sustained operation at that speed makes centrifugal stress the first limiting factor.

How much heat does the carbon-steel hub generate running all day with a Buna-N spider at 100 RPM?

At 100 RPM the Buna-N spider transmits 0.069 hp, so the hub itself contributes minimal heat; most warmth comes from spider hysteresis.
