Selection and applications

Check the profile and permitted minimum pulley diameter for the belt used, transmission ratio, speed and drive load. Select bushing 2517 to match both the pulley seat and shaft diameter. Pulley and bushing are ordered as two separate products. NERON in Piła helps select industrial drive components.

Taper Lock 2517 bushing installation tips

  1. Before work, stop the drive, disconnect power and secure the machine against starting.
  2. Check type 2517 compatibility, bushing bore against shaft diameter, and key connection requirements. Clean mating surfaces; do not fit to a damaged shaft.
  3. Seat the bushing and pulley and fit the screws in the assembly holes in the sequence specified in the instructions supplied with the Hubber bushing.
  4. Use a torque wrench and the torque specified by the manufacturer of the specific bushing. If you do not have this value, obtain it before installation; do not tighten by feel.
  5. Check pulley alignment, belt tension and guards according to the machine documentation. Remove according to the bushing instructions, without random blows or excessive force.

These are brief selection and installation tips, not a substitute for the manufacturer's instructions.

The graphic is a shared original illustrative visualisation of a three-groove spoked pulley with an empty seat, without a bushing. The table specifies the dimensions of the particular variant, not the graphic's proportions.

The illustrative diagram shows D — datum diameter, Da — outside diameter, B — rim width. Dimension values are in the table. The number and geometry of spokes in the shared visualisation and diagram are illustrative. The diagram is not for measurement or production.
