釋義

a type of fit between two mating machine parts where a small, deliberate gap allows the parts to move smoothly against each other along a common axis without sticking or binding

例句

collocation: specify a sliding fit for [part]

A sliding fit between the shaft and the bearing allows smooth rotation under normal loads.

pattern: sliding fit + between + [part A] + and + [part B]

同義詞

    broader category that includes sliding fit as one subtype; any fit with a guaranteed gap between parts

  • close running fit

    specific ISO fit category (H7/g6) very similar to sliding fit, used for precision sliding applications

反義詞

用法筆記

In engineering drawings, sliding fit is one of several standard fits defined by organisations such as ISO and ANSI. The exact gap depends on the nominal diameter of the parts and the required tolerance grade. A sliding fit has more clearance than a transition fit but less than a loose running fit.

常見錯誤

❌A sliding fit means the parts are loose and can wobble.
✅A sliding fit allows smooth, guided movement but does not permit wobble or side-to-side play.
💡a sliding fit is deliberately tight enough to guide the parts while still allowing free movement.
❌Any close-fitting part that moves is a sliding fit.
✅A sliding fit is a specific engineering classification with defined tolerances.
💡not every close-moving fit qualifies; the clearance must fall within standardised limits.
