Fit | Tolerance

Every fit falls into one of three categories based on the interaction between the hole and shaft tolerance zones.

: H7/p6 (light press), H7/s6 (medium drive fit for gear hubs). Fit Tolerance

: The shaft is always smaller than the hole, ensuring a gap for movement. Every fit falls into one of three categories

: Rotating shafts, sliding parts, or items that need easy hand-assembly. Fit Tolerance

: H7/g6 (precision sliding), H11/c11 (loose agricultural machinery).

: High-precision location where parts need to be snug but removable. Examples : H7/k6 (locational transition for dowel pins). 2. ISO 286 Notation System
