* R indicates riveted, C indicates cottered, C/R indicates available w ithcottered or riveted pins.

* * Width betw een roller link plates (W) is slightly narrower t han ANSIstandard, however this chain runs on standard sprockets.

RS Drive LAMBDA

Notes:1. Drive and Conveyor series LAMBDA chains cannot be intercoupled

or interchanged.2. The heavy roller link plates slightly increase the w idth, which

means Drive LAMBDA connecting links are required.

3. Connecting links for RSD80-LAMBDA to RSD140-LAMBDA andRSD80(H)-2LAMBDA to RSD140(H)-2LAMBDA have cottered pins.

4. Double Strand Drive LAMBDA requires heavy-series sprockets.

Notes:1. Conveyor LAMBDA should not be used in drive applications. It is designed for conveyor applications w here the speeds are generally lower and the center distances are longer than those found

in drive applications. Conveyor series LAMBDA, except for RSC35-LAMBDA, has the same dimensions and the same working load as our standard attachment chain and the same link platethickness as standard. RSC35 standard connecting links cannot be used for RSC35-LAMBDA due to the difference in pin diameter.

2. Drive and Conveyor LAMBDA chains cannot be intercoupled.3. Connecting links for RSC80-LAMBDA to RSC100-LAMBDA and RSC80NP-LAMBDA to RSC100NP-LAMBDA have cottered pins.4. RSC35-LAMBDA lasts up to 5 times longer than standard roller chain without additional lubrication.

Notes:1. Conveyor LAMBDA should not be used in drive applications. It is designed for conveyor applications w here the speeds are generally lower and the center distances are longer than those found

in drive applications. Conveyor series LAMBDA has the same dimensions and the same working load as our standard attachment chain. All link plates have the same thickness as standard.2. Drive and Conveyor LAMBDA chains cannot be intercoupled.3. Connecting links for C2080H-LAMBDA to C2100H-LAMBDA and C2080HNP-LAMBDA to C2100HNP-LAMBDA have cottered pins.

Basic Formula for Chain Drive

1 . Ch a i n Sp ee d ( S )

S( ft/ m i n ) = P N n

Where

P = C h a i n p it ch ( i n c h )

N = Num ber o f teeth /sp rocke t

n = R e vo l u t io n s p er m i n u t e ( r p m )

2 . Ch a i n Te n si on ( T )

T ( lbs ) = 33 ,000 x HP

SWhere

S = C h a i n s p ee d ( ft / m i n )

HP = Horsepower to be t ransm i t ted (HP)

Step 4 .Determine the number o f tee th for

is appropria te for the speed an d ho rsepower of the a pplication. Select

the proper ch ain type, chain size, and sprocket s ize.

Refe r to the n um ber o f revo lu t ions o f the h igh speed sha f t ( the d r iving

sha ft when the speed is reduced; the driven sh aft when th e speed is

inc reased ) an d the des ign HP va lue . Fo r smoo th e r cha in d r ive , a

Step 5 .Check the d imensio ns o f the s prockets .

Afte r de te rm in ing the n um ber o f teeth necessa ry fo r the sma l l

sprocket diam eter satisf ies the space l im itation.

Step 6 .Determine the number of teeth for the large sprocket.

Multiply the n um ber of teeth for the sm all sprocket by the speed ratio .
