Key And Keyway Dimensions: The 2026 Universal Guide For Shaft Security S Photos Public Domain
Standard metric shaft key and keyway dimensions chart in mm the key dimensions listed in the following table refer to nominal size, which provides a standardized reference for selecting and specifying keys to ensure compatibility between components from different manufacturers. Metric nominal dimensions, tolerances and gauging requirements bs iso 4156:2005_1 Learn everything about keyway dimensions, types, tolerances, design, and how to calculate keyway depth and width with formulas and standard keyway size charts for accurate mechanical design.
Teri Lynge: The Key
Key dimensions the inch and metric dimensions here correspond to common values All dimensions given in inches Detailed width tolerance information is best drawn from the manufacturer
This pa note will explain the uses of keys and keyways in pulleys and bushings, and present current industry standards for key and keyway component sizing.
This guide will walk you through what a keyway is, why it matters, the different types, how sizing works, and provide you with a detailed keyway size chart in both metric and imperial standards Key and keyway dimensions below is a reference on shaft diameters and the corresponding keys / keyways according to the prevailing standards. Keyway and key dimensions are standardized for shafts of different diameters The document provides tables with the standard sizes for keyways and keys in both english and metric units
The keyway width and depth as well as the key width and depth increase incrementally as the shaft diameter increases within specified ranges. + keyways will be furnished per iso/r773 and js9 width tolerance unless otherwise specified (dimensions comply with din 6885/1) † requires use of chamfered keys.

A list of standard keyway and corresponding key sizes for english shafts are listed below in table 1
The common specification dimension, keyway size, is highlighted. A keyed joint is used to ensure orientation or restrict rotational movement between parts, as in the case of joining a shaft with a coupling To create a keyed joint, a key is used that fits between slots manufactured into the two parts being joined The slot is defined as a keyway or a keyseat, depending on the whether the slot is located on an internal or external feature
Here we include dimensional information relating to parallel keys, both metric and imperial We also provide a handy link to our universal convertor. Machine elements hexagon socket head cap bolts (excerpt from jis b 1176 2014) hexagon bolts (excerpt from jis b 1180 2014) hexagon socket set screws (excerpt from jis b 1177 2007) hex keys (excerpt from jis b 4648 2008) parallel key and keyway sizes and tolerances retaining ring (excerpt from jis b 2804 2010) bearing mounting dimensions Keyway sizes keys and keyways are used to transfer torque from shafts to holes or vise versa
As a general rule, the key is a tighter fit to the shaft so that the key remains on the shaft during assembly and removal.
