Fitting Tolerances

The fitting tolerances for bronze bushings can be determined based on the shaft and hole dimensions:

Shaft Tolerances

  • Shaft diameter (d): h7 or h8 tolerance class
  • The h7 tolerance class has a tighter fit compared to h8

Hole Tolerances

  • Hole diameter (D): H7 tolerance class
  • The H7 tolerance class is commonly used for bronze bushings

Length Tolerance

  • Bushing length (L): ±0.25 mm tolerance

The h7 and H7 tolerance classes provide a sliding fit, which is suitable for bronze bushings. The tight tolerances ensure a smooth operation and minimize play between the shaft and bushing.The ±0.25 mm length tolerance allows for some variation in the bushing length while still maintaining the proper fit and function.It’s important to note that these tolerances may vary depending on the specific application and manufacturer requirements. Always refer to the manufacturer’s specifications or industry standards for the most accurate and up-to-date information.
