Timing belt pulley XH 200 z=28 for Taper-Lock bush 2517 steel

Product Description

Timing belt pulley XH 200 z=28 for Taper-Lock bush 2517 steel - for XH belts with a pitch of 7/8" (22.225 mm). 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. 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.

Designed for synchronous drives in: very heavy industrial drives, construction and mining machinery.

FAQ

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.

How do you choose a pulley for a toothed belt?

The key is matching the series (XH = pitch 7/8" (22.225 mm)) and the belt width (200 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.
