UHMW SPROCKETS

 

B.I.R.S Machine & Supply is a distributor of UHMW-PE Sprockets. UHMW-PE Sprockets are

used in food processing, bottling plants, wastewater, medical industry and wood processing

plants.

 

The excellent abrasion resistance of UHMW polymer is due to its ultra-high molecular weight. The abrasion resistance allows UHMW to be used as a bearing surface or sprocket contact point, reducing associated wear to mating components. UHMW outwears polished stainless steel by a factor of 5:1. This fact makes it ideal for conveyor wear points such as; chain guide, belt slider beds, dump truck liners, and general power transmission equipment. The durability is high, no particles will wear off or leave a residue...meaning it is approved by the FDA for contact with food. UHMW is very corrosion resistant. One form of corrosion is the continuous presence of water on a material. UHMW will NOT absorb any water over time. It is also very abrasion resistant. Some other beneficial aspects of this material are the good flow characteristics and its ability to absorb shock.

 

UHMW has a very low co-efficient of friction and even ice will not stick to its surface. Another outstanding property is its high impact strength, which is maintained down to very low temperatures. The impact performance under multi-axial shock stress and high stress rate is remarkable. UHMW is available in sheet form or rod stock and is quickly machined. Unconventional machining techniques, allow parts to be fabricated far quicker than steel components.

The most common material used for roller chain sprockets larger than #35 chain is UHMW-PE. With an excellent flexural modulus, UHMW-PE slightly deforms under load to evenly distribute the weight of the load among several sprocket teeth. This gives UHMW-PE sprockets the ability to handle good loads while increasing chain life.
