Product Description

V-belt pulley SPA 160/4, 4 grooves, for Taper-Lock 2517, cast iron is a V-belt pulley with SPA grooves made to ISO 4183 and DIN 2211, with a datum diameter of 160 mm. Number of grooves: 4. It is made of EN-GJL-200 grey cast iron, phosphated and statically balanced for a peripheral speed of up to 35 m/s.

The pulley has a seat for a Taper-Lock 2517 clamping bush (bush sold separately) - the bush bore is chosen to suit the shaft, up to 60 mm, without boring the pulley. The face width is 65 mm with a groove pitch of 15 mm.

Technical data

Applications

Belt drives in construction and agricultural machinery, generating sets, centrifuges and production lines.

Frequently asked questions

Which V-belt pulley has the SPA profile, a datum diameter of 160 mm and 4 grooves?

This is the v-belt pulley SPA 160/4, 4 grooves, for Taper-Lock 2517, cast iron. The outside diameter is 165.5 mm and the face width 65 mm.

Which V-belt fits this pulley?

A narrow SPA V-belt (12.7 × 10 mm) to ISO 4184 / DIN 7753. Classical A belts (13 mm) to DIN 2215 also run in SPA grooves, but transmit less power. The number of belts equals the number of grooves (4).

Which Taper-Lock bush do I need for this pulley?

A Taper-Lock 2517 bush. The bush is bought separately and its bore is chosen to match the shaft diameter - up to 60 mm for this pulley. The bush clamps onto the shaft when the screws are tightened, so the pulley does not need to be bored and removal is easy.

How do I calculate the belt speed on this pulley?

Belt speed v = π × dp × n / 60 000, where dp is the datum diameter in mm and n is the speed in rpm. On this pulley at 1450 rpm the belt runs at approx. 12.1 m/s. The pulley is statically balanced up to 35 m/s.

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

The ratio is the datum diameter of the driven pulley divided by that of the driving pulley, e.g. 160 / 320 = 0.5. Because of the slight slip of the V-belt, the actual speed is approx. 1-2% lower.

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.
