How do you size a keyway?

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

What is the standard keyway for a 5’8 shaft?

Dimensions: Shaft Diameter (A): 5/8″ Keyway Width (B): 3/16″ Keyway Depth (C): 3/32.

What is a P9 tolerance?

The second is a P9 tolerance. This is an undersized clearance. The advantage of the Js9 tolerance is that the key can be inserted and the gear manipulated without much difficulty. Whereas the P9 tolerance is a press fit tolerance.

What does C keyway mean?

Cylinders are made so that only a unique key design can operate the locking function of the cylinder. This unique key design is the cross-sectional shape or configuration applied lengthwise to a key blade. This shape is often referred to as the keyway or key section.

Are Keys standard?

This International Standard specifies the dimensional characteristics of tangential keys and of their corresponding keyways in shaft and hub. It also gives the relation to be observed between the diameter of the shaft and the section of the key.

How deep do you cut a keyway?

Milling of keyway Layered milling is to cut the keyway layer by layer, the depth of each operation is only 0.5-1 mm, then carry out the back and forth milling with a larger feed rate until it reaches the desired depth.

How long should a shaft key be?

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.

What is the meaning of H7 tolerance?

International Tolerance grades For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit. For a shaft of the same size, h6 would mean 10+0−0.009, which means the shaft may be as small as 0.009 mm smaller than the base dimension and 0 mm larger.

What are the types of keyway?

There are many types of keyways, but most homes have locks with one of two of the most common keyways – KW1 and SC1. The SC stands for “Schlage,” and the KW stands for “Kwikset” – two common lock manufacturers. Stone Harbor door locks are available with both of these keyways.

What kind of key stock do I Need?

This key stock is stepped to match repaired keyways in shafts or gears. Cut it to length to create the machine key you need. Straight keys, with a square or rectangular cross section, are the most common type of key. Install them in keyways to transmit torque from shafts to gears and other components.
