Timing belt pulley H 300 z=120 for Taper-Lock bush 3030 cast iron

Product Description

Timing belt pulley H 300 z=120 for Taper-Lock bush 3030 cast iron - for H belts with a pitch of 1/2" (12.7 mm). Made of grey cast iron with a pearlitic structure.

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.

Used in machines requiring accurate motion transmission: heavy industrial drives, agricultural machinery, machine tools, presses.

FAQ

Do you ship pulleys from stock?

The stock level is shown above the price and may vary depending on the warehouse.

What materials do you use for pulleys?

Cast iron dampens vibrations excellently, is resistant to abrasion and dissipates the heat generated by belt friction very well - ideal where quiet and stable drive operation matters.

Does shaft runout damage pulleys?

Yes - shaft runout causes cyclic jerking of the belt, which leads to cracking of the pulley hub and accelerated belt wear. Before mounting the pulley, it is worth checking the shaft runout with a dial indicator.

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.
