Timing belt pulley H 300 z=72 for Taper-Lock bush 2517 cast iron

Product Description

Timing belt pulley H 300 z=72 for Taper-Lock bush 2517 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. 50 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: heavy industrial drives, agricultural machinery, machine tools, presses.

FAQ

How do you choose a pulley for a toothed belt?

The key is matching the series (H = pitch 1/2" (12.7 mm)) and the belt width (300 mm). The drive ratio is calculated by dividing the number of teeth of the driven pulley by the number of teeth of the driving pulley.

How can you recognise a worn pulley groove?

If the bottom of the groove is shiny, the belt has bottomed out and no longer wedges against the flanks - the pulley needs replacing. Profile gauges are used for checking.

How does excessive belt tension affect the bearings?

Excessive radial force puts high loads on the bearings, leading to overheating and premature failure. The correct tension is specified by the belt manufacturer.

Do you ship pulleys from stock?

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