Applications
(3) Ultra Super Chain is not available in multiple strand. (4) Due to the hardness of plates being higher than other carbon steel roller chains, Ultra Super Chains have a greater risk of hydrogen embrittlement. Other points of notice are the same as Super-H Roller Chain.
1.3 LUBE-FREE CHAINS
1.3.1 LAMBDA ® Roller Chain Transmission and conveyor: Lube-free type, drive transmission
Application Example LAMBDA Roller Chains do not require additional lubrication. This makes them ideal for “clean” applications like final assembly areas, paper production, and other operations where lubrication could affect the product on line. LAMBDA Roller Chains are available in drive or conveyor styles. (See Figure 1.7.)

Figure 1.7 LAMBDA ® Lube-Free Chain
Construction and Features LAMBDA Roller Chains are designed for long wear life without additional lubrication. The bushings are made of oil-impregnated sintered metal, and the pins are specially coated. LAMBDA Roller Chains also have rollers, which make them different from other lube-free chains. (The SL series, for example, does not have rollers.) The features of LAMBDA Roller Chains are as follows: (1) LAMBDA Roller Chains outlast Standard Roller Chains without lubrication up to 30 times longer at low speed (about 25 m/min.) and seven times longer at medium speed (about 127 m/min.). (See Figure 1.8.)
