Timing pulley PolyChain GT 8M z=36 for 62 mm belt, pilot bore, C45 steel

Product Description

Timing pulley PolyChain GT 8M z=36 for 62 mm belt, pilot bore, C45 steel is a timing (synchronous) pulley for PolyChain GT 8M belts: pitch 8 mm, 36 teeth, belt width 62 mm. The pulley has teeth matched to PolyChain GT belts with a pitch of 8 mm, designed for high-power drives with a narrow belt. It is made of C45 steel.

The pitch diameter is 91.67 mm and the outside diameter 90.07 mm. The pulley has a hub with a pilot bore Ø15 mm, which is bored out to the shaft size and completed with a keyway or a set screw hole. The flanges (Ø97 mm) guide the belt and stop it running off the pulley.

Technical data

Applications

Replacement for chain drives and multi-groove V-belt drives in industrial, paper and agricultural machinery.

Frequently asked questions

Which timing pulley has the PolyChain GT 8M profile, 36 teeth and a pitch diameter of 91.67 mm?

This is the timing pulley PolyChain GT 8M z=36 for 62 mm belt, pilot bore, C45 steel. The outside diameter (over the tooth tips) is 90.07 mm. The pitch diameter is calculated as Dp = pitch × z / π = 8 × 36 / π.

Which timing belt fits this pulley?

A PolyChain GT 8M belt 62 mm wide. Standard HTD belts are not used with this pulley because the tooth shape is different.

Does this pulley work with an HTD 8M belt?

No. The PolyChain GT tooth shape differs from HTD, so the pulley and the belt must have the same PolyChain GT profile and the same pitch.

How do I prepare the bore for the shaft?

The pilot bore Ø15 mm is bored out on a lathe to the shaft size (usually to tolerance H7) and a keyway is cut to DIN 6885. The pulley is secured axially with a set screw in the hub. The maximum bore depends on the hub diameter (75 mm) - enough wall thickness must remain after machining.

How do I calculate the ratio of a drive with this pulley?

The ratio is the number of teeth of the driven pulley divided by the number of teeth of the driving pulley, e.g. 36 / 18 = 2. A timing belt drive has no slip, so the ratio is constant.

What are the flanges for?

The flanges guide the belt and prevent it from running off the pulley. In a typical drive it is enough for one of the two pulleys, usually the smaller one, to have flanges.

What does the lead time depend on?

When ordering, please check the current stock level of this pulley - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may differ between warehouses.
