A – ENGINEERING CLASS CHAINSUNION CHAIN DIVISION - DRIVE CHAINSDrive ChainsENGINEERING CLASS DRIVE CHAINKeep Your Operation Moving withUnion ChainUnion Drive Chains are designed to exceed the listed ultimatestrength ratings. 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 loads.Reduce Maintenance Costs and DowntimeUnion Drive Chains stand up to the toughest environments forhour after hour of uninterrupted service.Precision Manufacturing MeansGreater Fatigue StrengthUnion Engineering Class Drive Chains are built to withstandthe most rugged conditions. We use the latest manufacturingand heat-treating techniques to manufacture every component.Each component is carefully machined to close tolerances toensure precise pitch control for smooth sprocket/chain interaction. That means longer service life for chain and sprockets. Pre-testedAdd 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 applications.Every 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.A-1 Optimum strength Fatigue resistant Alloy steel parts Press fit construction Accurate pitch controlYour equipment is on the line. Count on Union Chain.
A – ENGINEERING CLASS CHAINSQuality ComponentsHigh-Strength SidebarsSidebars for Union Drive Chains with an ultimate strengthrating higher than 112,000 pounds are manufactured fromalloy 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 precise pitch control, distributing the load equally and providingsmooth sprocket interaction.Alloy Steel Induction Hardened PinsAll Drive Chain pins are made from alloy steel and arethrough-hardened for toughness and strength. In addition,chains designed for heavy duty power shovel applicationshave ground bearing surfaces and full round induction hardening. This provides the best combination of high yield strengthand superior wear resistance.Precision Machined BushingsBushings for Drive Chain are precision machined to providesmooth bearing surfaces—that means less resistance on-line.They are through-hardened or case hardened to meet yourapplication. The result is smooth riding bushings that last.Shock-Resistant RollersOur rollers are made from a high quality material for usewhen 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.A-2

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. It is advisable to consult Unionengineers for selections of this nature. 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 andminimum speed and HP to be transmitted at each speed. Diameters of the driving and driven shafts.

A – ENGINEERING CLASS CHAINSUNION CHAIN DIVISION - DRIVE CHAINSStep 2: Select Service FactorFrom the Service Factors Table 2 below, select the numberunder the type of input power and opposite the classof driven load that most closely relates to the application.Table 2 — Service FactorsType of Input PowerType ofDriven LoadInternalCombustionEngine withHydraulicDriveElectricMotor orTurbineInternalCombustionEngine withMechanicalDriveUniformModerate ShockHeavy Shock1.01.21.41.01.31.51.21.41.7Step 3: Calculate Design HorsepowerDesign Horsepower HP x Service Factor.Step 6: Determine Number of Teeth in Large SprocketN rnRThe number of teeth in the large sprocket equals the RPM of thesmall sprocket times the number of teeth in the small sprocketdivided by the RPM of the large sprocket. Note: Hardened teethare suggested for sprockets with less than 15 teeth, speedsgreater than 600 RPM, ratios over 4:1, or in heavy loading orabrasive environments.Step 7: Determine Suggested Minimum CenterDistance; C Chain PitchesC 2N n6This formula is to be used as a guide to MINIMUM centerdistances only. The final selection may vary slightly to suitclearance dimensions.The Design Horsepower equals the Horsepower to be transmitted multiplied by the Service Factor selected in Step 2.Step 8: Check Final Drive DesignBe sure that the sprockets and chain will fit into theavailable space.Step 4: Select Chain PitchUse the Quick Selection Chart (page A-10), to find chain pitch,as follows:Step 9: Specify SprocketsSpecify the sprockets selected. See Sprocket section in thiscatalog. Also, refer to Section C for standard keyway andset screw dimensions. Locate the design horsepower from Step 4 on thevertical axis. Locate the RPM of the small sprocket on the horizontal axis. The intersection of the two lines (design horsepower andRPM) will be in an area designated with the suggested chainpitch. If the intersection is near the borderline of the pitcharea, the pitches on both sides of the line should be evaluatedto obtain the most suitable selection. If the chain is not listed in the Quick Selection Chart, go to theWorking Load Selection Guidelines.Step 5: Select Number of Teeth in Small SprocketHorsepower Table Ratings for single strand chains are givenon pages A-11 A-14 for each chain pitch. Turn to the pagegiving the chain pitch obtained in Step 4 and select the numberof teeth in the small sprocket: Read down the column in the Horsepower Ratings Tableunder the RPM of the small sprocket until the requested HPTable Rating is located. Read across the table to the first column (Number of Teeth Small Sprocket). This is the smallestnumber of teeth to specify for this application. Note the lubrication type specification in the table for thischain. This type of lubrication must be used to obtain reasonable service life.Step 10: Calculate Chain LengthTo order the proper length of chain, use the following calculation:Chain Length in Pitches S 2C K2C Add number of teeth in small sprocket and number of teeth inlarge sprocket to obtain S. Subtract number of teeth in small sprocket from number ofteeth in large sprocket to obtain value D. Find D in Table 3,and note corresponding value K. Divide center distance in inches by pitch of chain, obtaining C. Using these values, solve the formula above.Chain Length Length in Pitches x Pitch in Inches in Feet12A chain cannot contain a fractional part of a pitch. If the chainlength obtained contains a fractional part of a pitch, use the nexthigher whole number.GlossaryN Number of teeth in large sprocketn Number of teeth in small sprocketR RPM large sprocketr RPM small sprocketC Shaft center distance in pitchesS N nD N-nA-7

A – ENGINEERING CLASS CHAINSUNION CHAIN DIVISION - DRIVE CHAINSAlternate Working Load Selection GuidelinesSelection of drive chains not listed in the Quick Selection Chartby the Working Load method:To use a chain that is not listed in the Quick Selection Chart ,the proper chain can be selected from the working load valuesgiven in the chain listings. The working load required can bedetermined from the following:Working Load(HP) x (396,000) x (E) x (V)(CP) x (T) x (RPM)Where:HP Actual horsepower required. (Use motor HP if actualis not known.)CP Chain pitch (inches)T Number of teeth in smaller sprocket.
