2 These ratings are very significant. Chains withgreater ultimate strength have higher actual yield and greaterfatigue strength. With Union chains, you get extra reservestrength to withstand high shock Manufacturing Means Greater Fatigue StrengthUnion ENGINEERING class Drive Chains are built to withstand the most rugged conditions. We use the latest manufacturing and heat-treating techniques to manufacture every component is carefully machined to close tolerances toensure precise pitch control for smooth sprocket/ CHAIN interac-tion. That means longer service life for CHAIN and the Power of AlloyWhen parts require extra hardness, we use alloy steel to makethe components. This provides more uniform core strength,which is particularly important for heavy duty Union Drive CHAIN with an ultimate strength rating higherthan 112,000 pounds is made entirely of alloy steel. All UnionDrive Chains are furnished with alloy steel pins. Reduce Maintenance Costs and DowntimeUnion Drive Chains stand up to the toughest environments forhour after hour of uninterrupted service.

3 Optimum strength Fatigue resistant Pre-tested Alloy steel parts Press fit construction Accurate pitch controlYour equipment is on the line. Count on Union ENGINEERING class CHAINSA-2 Quality ComponentsHigh-Strength Sidebars Sidebars for Union Drive Chains with an ultimate strength rating higher than 112,000 pounds are manufactured from alloy steel and are through-hardened. This adds strength andextends the service life of the CHAIN . In addition, our advancedmanufacturing techniques ensure accurate hole size and pre-cise pitch control, distributing the load equally and providingsmooth sprocket Machined BushingsBushings for Drive CHAIN are precision machined to providesmooth bearing surfaces that means less resistance are through-hardened or case hardened to meet yourapplication. The result is smooth riding bushings that Steel Induction Hardened PinsAll Drive CHAIN pins are made from alloy steel and are through-hardened for toughness and strength. In addition,chains designed for heavy duty power shovel applications have ground bearing surfaces and full round induction harden-ing.

4 This provides the best combination of high yield strengthand superior wear RollersOur rollers are made from a high quality material for use when critical tolerances and superior finish are required. Thenthey are through-hardened to withstand high shock loads. Forchains with high ultimate strength ratings, rollers are typicallymade from alloy steel.

To determine thesuggested CHAIN , follow Steps 1-10 of the Standard SelectionProcedureon pages A-5 through A-7. An example procedure isshown on page A-15. Each selection procedure is intended to be used for EngineeringClass Drive CHAIN (ASME/ANSI Standard ). A-6A ENGINEERING class CHAINSR equired Information for Drive Selection Type of input horsepower (electric motor, internal combustionengine, etc.). Type of equipment to be driven.

10 Horsepower to be transmitted. Full load speed of the fastest running shaft (RPM). Desired speed of the slow speed shaft (RPM).Note:If speeds are variable, determine maximum and minimum speed and HP to be transmitted at each speed. Diameters of the driving and driven shafts. Center to center distance of :If this dimension is adjustable, determine amount of adjustment. Position of drive and space limitations, if any. Proposed method of lubrication. Conditions of drive. Drives with more than two sprockets,idlers, or unusual conditions such as severely abrasive orcorrosive atmosphere, extremely high or low temperatures,severely fluctuating loads, frequent stops and starts, etc.,require special consideration.
