Selection and applications
Select belt profile, datum diameter, number of grooves, ratio and drive load. The bushing must be type 1108 with a bore suitable for the shaft; also check the key connection design. NERON in Piła helps select power transmission components. Sold from 1 piece, fulfilment within 48 hours. The price is for one pulley without bushing.
Taper Lock 1108 installation tips
- Stop the drive and secure it against starting. Check the components and bushing compatibility with the pulley and shaft.
- Clean and degrease the tapered surfaces of the bushing and pulley, and the shaft. Match the half-holes. Prepare the screw threads according to the manufacturer's instructions; do not lubricate the taper.
- Seat the assembly on the shaft, check the key and pulley alignment. Tighten the screws evenly with a torque wrench.
- For the Optibelt 1108 bushing, the instructions specify two screws and 5,7 Nm torque. For a bushing from another manufacturer, check its instructions — do not transfer this value automatically.
- After brief operation, approx. 0,5–1 hours, stop and secure the drive, then check tightening. Check alignment and belt tension.
