SP pulley with closed ball bearing

This range of pulleys has the following features:

  • Highly quality polyamide pulley
  • Precise shielded bearing with small tolerances, lubricated, grime resistant
  • SP pulleys are recommended for more precise applications because of their high rotational speed and high bearing load

Load capacity of SP-bearings

The loads shown in the spreadsheet represent approximate dynamic load capacities on the bearing
under normal conditions, with constant load and speed, at an average working life of 2500 hours assuming correct installation, clean working conditions and optimal lubrication.

For speeds other than 500 rpm the load capacity is calculated as follows:
