Design Debate: Switching From Sae To Metric Keyway Sizes In 2026 Lpr Olmakers Bushes 6 60mm Aprica Branded

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 For instance, a typical metric square keyway might have dimensions of 5 mm x 5 mm or 10 mm x 10 mm, allowing for appropriate torque transmission depending on the application. 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.

A comprehensive overview of keyways, how they function, and the key and keyway dimensions/sizes involved in their design. Common metric keyway types include the square and rectangular keyways, similar to their imperial counterparts but with metric dimensions The keyway dimensions are also different from the english system

Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway.

When working with power transmission components, selecting the correct keyway size is essential for ensuring proper fit and function Key dimensions the inch and metric dimensions here correspond to common values Detailed width tolerance information is best drawn from the manufacturer Metric nominal dimensions, tolerances and gauging requirements bs iso 4156:2005_1

Technical data for metric keys and keyways per iso/r773 Includes js9, p9, d10 tolerances, dimensions in mm & inches for couplings. Keyways index keys and keyway dimensions keyways index A list of the standard key sizes and corresponding keyways for metric shafts are listed below in table 2

The common specification dimension, key size, is highlighted.

Standard key and keyway sizing english dimensions W x t 1 metric dimensions: It includes seven sae sizes and seven metric sizes, all built with long shafts for deep screws and shorter ends for tighter. Parallel key and keyway sizes and tolerances is provided.

Keyways index keys and keyway dimensionskeyways index Shaft key selection and keyway design should consider key types, correct fit, key material, shaft material, load, fatigue & safety factors To secure the hub and shaft and stop relative movement between a power transmitting shaft and an attached component, a key and the keyway combine to form a keyed joint. Bore, keyway & setscrew information standard keyway & setscrew sizes

Standard setscrew locations if one setscrew is furnished the location will be 0°

If two setscrews are furnished the locations will be 0° and 90°, unless otherwise specified. This page provides a detailed keyway chart to help engineers select precise seal fits for transmission applications in industrial environments. Metric keyway calculator key dimensions Parallel keys are most commonly used

The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion. Key and keyway dimensions below is a reference on shaft diameters and the corresponding keys / keyways according to the prevailing standards.
