Applications
Sprockets Standard sprockets may be used. In some cases, side rollers may interfere with the sprocket hub. Additional machining of the hub might be required. Selection and Handling (1) Although both R-rollers and S-rollers are commonly used in Side Roller Chains, R-rollers should be considered if either of the following condi- tions exist: • The overall length of the machine is more than 10 m. • The chain speed is more than 20 m/min. (2) R-rollers have lower coefficient of friction (without lubrication, R-roller: 0.12; S-roller: 0.21). (3) Select Side Roller Chain according to the chain tension and allowable roller load. Make sure to consider the tension due to the accumulating mode when you calculate total chain tension. (4) Side rollers can be installed in alternating positions, staggered or parallel. Staggered rollers tend to allow pallets to run smoother. (5) Side Roller Chain requires lubrication to reduce wear elongation and to reduce noise level. NOTE: Lubrication may affect (delay) acceleration; therefore, please apply carefully. Chains for Special Applications Side Roller Chain is available in LAMBDA ® construction for lube-free operations. Technical Trends Chain manufacturers are working on new chain designs that quiet operation noise. Chain kits, including chain, guides, sprockets, and other components are a focus of chain manufacturer development plans. Large pitch side roller conveyor chains are available to handle heavier loads.
