What material are sprockets made of?
The sprocket is normally made of alloy steel and is tempered and case hardened at the tooth area in order to enhance the wear resistance of the material. By construction the sprockets either posses a hub with key for driving or holes (in automobiles) in order to be mounted.
What steel is used for sprockets?
As a standard, Brentwood’s Polychem sprocket gears use grade 316 stainless steel hardware. Other suppliers often use 18-8 or grade 304 stainless steel. Grade 316 stainless steel is more resistant to corrosion than the typical alternatives, so it is important to know what is being offered when comparing prices.
What are the different types of sprocket?

- Chain sprockets.
- Duplex sprockets.
- Industrial sprockets.
- Drive sprockets.
- Triplex sprockets.
- Shaft sprockets.
- Simplex sprockets.
- Single pitch and double pitch sprocket.
What causes sprocket wear?
Wear on the sides of sprocket teeth generally indicates improper installation of sprockets and/or shafts. If the shafts are out of parallel or not in the same plane, non-symmetrical wear will appear on sprockets or chain rollers. MAINTENANCE: After proper alignment is made, re-tighten set screws in sprocket hubs.
What is the best material for sprocket?
Steel is stronger and slightly cheaper but aluminium is lighter and more attractive. For durability and longevity there is no doubt that a steel sprocket is best. Specifically, an induction hardened steel rear sprocket is strongest and will last the longest.
Which material is best for sprocket?
Are Martin sprockets hardened?
OVERVIEW. Martin saber tooth sprockets have hardened teeth, which provide longer chain and sprocket life.
What is Type B sprocket?
Type B sprockets, which have a hub on one side. Type C sprockets, which have hubs of equal thickness on both sides of the plate. Type C offset or Type D sprockets, which also have two hubs. However, each hub has a different thickness, making the sprocket asymmetrical.
How long do sprockets last?
A common rule is to replace both front and rear sprockets every time you replace your chain. This is a good rule to follow if your chain has lasted for its full life of, say, 15,000 miles. But, sometimes a sprocket replacement can wait in cases where you’re replacing a prematurely worn chain.
How do I know if my sprocket is bad?
Look closely at the sprocket teeth to see if they have become sharp at the tips and/or slightly curled. The teeth on a new sprocket are straight and have a flat or domed shape at the tip. If the teeth are sharp, the sprocket is worn.
