Timing belt pulley 8M 85 z=72 for Taper-Lock bush 3020 Steel

Product Description

Timing belt pulley 8M 85 z=72 for Taper-Lock bush 3020 Steel - for HTD 8M belts with a pitch of 8 mm (HTD). Made of C45 steel.

The Taper-Lock system eliminates the need to bore out the hub. The bush slides into the tapered seat of the pulley and, after the screws are tightened to a torque of approx. 80 Nm, it clamps onto the shaft without a press or special tools. Removal is just as simple - one screw inserted into the removal hole pushes the bush out without risk of damaging the shaft.

Typical applications: industrial drives, heavy machinery, production lines.

FAQ

How do I mount the pulley on a Taper-Lock bush?

The bush is inserted into the tapered seat of the pulley, placed on the shaft and the screws are tightened to a torque of approx. 80 Nm. The pulley is ready in a few minutes, without a press or special tools.

How do I choose the Taper-Lock bush number?

The bush number (3020) is assigned to the pulley and determines the size of the seat. You only choose the bore diameter of the bush to suit your shaft. The maximum bore for this pulley is 150 mm.

How do I remove a pulley with a Taper-Lock bush?

Unscrew the mounting screws and screw one of them into the removal hole in the bush - it acts as a puller and pushes the bush out of the seat without damaging the shaft, without a press or hammer.

What shaft tolerance do you recommend?

The recommended shaft tolerance is h9 or h11. The shaft should be smooth and clean - rust or burrs will hinder proper clamping and may cause the pulley to slip under load.
