CHAIN GUIDES are simply a plastic profile used to carry a Roller Chain. For chains that run on metal guides, it is
quite easy to break down or exhaust by relentless pressure or resistance if regular lubrication is not well done.
People find that the ultrahigh molecular weight polyethylene (UHMWPE) is one of the toughest polyethylene
classifications available. This type of polyethylene has a molecular weight number in the millions, which gives it its
characteristic high degree of entanglement. People choose chain guides made of UHMW PE to replace metal
guides with the purpose of achieving quiet, smooth running and longterm functional reliability. UHMW chain
guides extend chain life, reduce noise and friction. They guarantee optimum running properties at the same time as
extremely high wear resistance.
Advantages of Railsung chain guides
· High wear resistance
· Very good slide properties
· Self-lubricating (no need for any oil lubrication at all)
· Extremely impact and break resistant, even at very low
· temperatures (up to -250°C)
· High resistance to chemicals
· Vibration-reducing properties
· No moisture absorption
· No corrosion
· Approved for use in the food industry (EU and FDA)
Chain types
Railsung specializes in making all types of Roller Chain Guides, all available in several grades of UHMW plastic:
black repro - for lower cost; oilfilled UHMW for higher speed; green repro which matches the European guides;
static-dissipative for conduction purposes; and HT for high temperatures up to 275 degrees. At Railsung, we have in
stock many types of ANSI roller chain inserts for conveyor chains. Typical styles include: Chain guides are available
in the channel style, raised track, and as a channel with a raised track. These chain guides are also available as
inserts for mounting channels. The channels are available as galvanized or stainless steel. A mounting channel is
welded or bolted into place and allows the UHMW to expand and contract without buckling. Stainless and Galvanized Mounting Channels Sold Separately.
Stock and individual production
We have an extensive range of guides for roller chains in stock that comply with DIN 8187 In the U.S., power
transmission chains must meet ANSI B29.1You can order them in standard sizes, or have a custom order. In
addition, we can manufacture economical and reliable special guides in accordance with your specifications even
in small quantities.
