Hole limit deviations

Hole limit deviationsISO 286 (JIS B 0401)A table of the upper-case tolerance classes, H7, G7, JS6 and so on.Shaft limit deviationsISO 286 (JIS B 0401)A table of the lower-case tolerance classes, h7, g6, js6 and so on.

Hole limit deviations for commonly used fits

Size range
(mm)		Hole dimensional deviations (unit: μm. The upper line is the upper deviation, the lower line the lower deviation)

Notes

  • References
    • JIS B 0401
  • How to read the size ranges, and how to read the deviations (units, upper and lower rows, and the dash), is explained behind the i in the table header.
