All toothed wheels look like sprockets but never performs alike. That makes the purchase of sprockets critical. A toothed wheel bought in place of a sprocket not only adds but multiplies your problems ,because a toothed wheel means:

• Inferior quality of raw material
• Uneven tooth cut by any ordinary method which in no case is a    hob cut
• Insufficient size of tooth pocket
• Inaccurate tooth form
• Inaccurate pitch diameter to match with the chain

All these is more than enough to kill your chain because: Insufficient tooth pocket, bad tooth profile and inaccurate pitch diameter doesn’t Allow  chain rollers to have perfect engagement with a tooth pocket. This comples The chain to impart load on the vertises of the teeth leading to uneven distribution of Load and early elongation of chains,which eventually results into a breakdown. Not only that it also increases the power consumption considerably which leads to low productivity and thereby low profits.

Some sprocket also looks like a toothed wheel but it stands out on performance. ‘Excel’ Precision sprocket means:

• High Grade Steel Material
• Precision Teeth cuts and teeth size which undoubtedly is a hob    cut
• Sufficient size of a tooth pocket for proper engagement of    chain rollers
• Accurate tooth forms
• Accurate pitch diameter to match with the pitch of a chain
• Accurate tooth profile and an excellent workmanship
• Flame hardened tooth which ensures longer life due to high    wear resistance
