Cast iron sprocket


The large sprocket is generally made of cast iron. High speed, heavy load or continuous transmission, low carbon alloy steel surface carburizing quenching or medium carbon alloy steel surface quenching. Cast iron chain wheel not less than ht150 can also be used for low speed, light load and large number of teeth. Cast iron sprockets are mainly used in sprockets with low requirements for high-precision control or complicated shapes, such as ring sprockets.

Cast iron sprockets

Cast iron wheels represent the right solution in case big sprockets are needed. here following the complete range of cast iron wheels divided by different pitch.

Sprocket Materiral

• Cast iron sprocket
Cast iron is the most common and economical material for flat steel belt sprockets, which are precisely cast by high grade iron. Other diameters are available on special orders.
Plastic sprocket
All plastic sprockets are fully machined to meet USDA and FDA food contact guidelines.
-UHMWPE can withstand temperatures up to 180 degrees Fahrenheit. Stock sprocket
It is ultra-high molecular weight.
-High temperature UHMWPE can withstand continuous temperatures up to 220 degrees Fahrenheit.
-The strength of nylon chain wheel is 2-3 times that of UHMW, which can withstand higher temperature.
Steel sprocket
-The FL sprocket has no flange and a protruding hub on one side to allow debris to fall through the belt.
-MT sprocket is made of solid steel sheet, or flange is welded on the base
Teeth for belt support. Flangeless and – MT sprocket teeth hardened to Rockwell 50-55
On the C scale. All other steel sprockets can have their teeth hardened as required.
• Stainless steel sprocket
The stainless steel sprocket is made of 18-8 stainless steel investment casting or completely machined from T-303 SS or T-316 SS. Full machined flanged (- FL) or machined tooth (- MT) sprockets made of various stainless steels are also available.
