Selection and applications

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.
