Just find some hose that matches the min OD of the ballscrew, probably around 22mm. Then you just roll the nut onto the hose. Carefully.. Also, if you have shop air available at the machine, you could add 1/8th fittings to either end of the bellows, or at the nut, and piss a teeny amount of air into each end of the bellows. A low pressure regulator or just a restrictor would work. A positive pressure on both sides of the nut will mean; - no equilibrium needed - will always be purged with clean air - dispense with a vacuum being generated on one side during travel which can suck dust in.
