american standard double pitch roller conveyor chains conforming to ansi b29.3 and b29.4 double pitch roller chains have twice the distance between rollers of corresponding standard roller chains for example ansi no 40 standard chain pitch is 1/2 ansi no 2040 chain pitch is 1 since double pitch chains contain only half as a many rollers bushings and pins they have lighter weight and greater economy than comparable standard chains they are suited for applications with slow-to-moderate speeds medium loads and long distances between sprockets including a variety of conveyor systems and material handling equipment ansi transmission series chains feature figure-8 side plates and standard size rollers cross+morse ansi conveyor series have straight side plates and either standard size or large rollers which are also available in thermoplastic large rollers are approximately twice the diameter of standard rollers they usually ride on tracks to reduce friction and the required horsepower to extend chain life double pitch chains are available in rivetted or cottered construction a variety of attachments links refer to page 24/25 can be fitted to all standard conveyor series chain also hollow pin extended pin and rollerless chains are available with many chains offered in stainless steel or plated finish refer to page 25 power transmission solutions te l +44 121 360 0155 transmission series chains to ansi b29.3 figure-8 contour of the transmission series side plates keeps chain weight to a minimum and permits use of sprockets with maximum hub diameters link plate thickness pins bushes and rollers are same as corresponding standard roller chain ansi no 2040 2050 2060 2080 2100 pitch p inches 1 11/4 11/2 2 21/2 inside width b min mm 7.85 9.40 12.60 15.80 19.00 roller Ø d1 max mm 7.95 10.16 11.91 15.88 19.05 pin Ø d2 max mm 3.96 5.08 5.94 7.92 9.53 plate depth g mm 11.8 15.0 18.0 24.0 30.0 plate thickness t mm 1.52 2.04 2.38 3.18 3.96 rivet pin length l max mm 16.6 20.2 25.0 32.6 39.2 length to cotter pin m mm 10.7 14.3 16.3 18.8 23.2 length to rivet pin n mm 8.3 10.1 12.5 16.3 19.6 bearing area cm2 0.44 0.70 1.06 1.79 2.62 tensile strength n 14,800 24,400 34,000 64,500 100,000 weight approx kg/m 0.45 0.67 1.02 1.65 2.89 fax +44 121 325 1079 conveyor series chains to ansi b29.4 standard and large diameter rollers conveyor series chains with standard size rollers have straight side plates for increased bearing area when sliding on guides or supporting products large size rollers support the chain and load holding them off the track to minimise friction and power requirements chains 11/2 pitch or greater have side plates of same thickness as corresponding ansi heavy series roller chains standard roller series email large roller series sales@crossmorse.com thermoplastic large roller series these chains are identical to large roller series except that the rollers are of thermoplastic material reducing weight by approximately one third horsepower requirements are lower and thermoplastic large rollers run quietly and smoothly are tough and wear-resistant require no lubrication and have improved resistance to corrosion chains with thermoplastic rollers are not recommended for operation below -17°c or above 80°c side plate height g 11.7 15.0 17.6 22.4 29.2 34.8 47.5 thickness t 1.52 2.04 3.18 3.96 4.75 5.54 7.14 pin dia d2 max 3.96 5.08 5.94 7.92 9.53 11.10 14.27 approx weight kg/m rivet pin length to length to tensile length conn pin rivet pin strength standard large thermol m n n roller roller plastic 16.6 20.2 28.3 35.9 42.5 52.7 66.1 10.7 14.3 16.6 20.4 24.9 30.8 38.7 8.3 10.1 14.1 17.9 21.2 26.3 33.1 14,800 24,400 34,000 64,500 100,000 130,000 227,000 0.48 0.79 1.37 2.26 3.42 5.50 8.70 0.82 1.25 2.10 3.29 5.58 8.50 13.30 0.49 0.81 1.40 2.27 ansi/cat part no standard roller c2040 c2050 c2060h c2080h c2100h c2120h c2160h large roller c2042 c2052 c2062h c2082h c2102h c2122h c2162h thermoplastic c2042d c2052d c2062d c2082d pitch p inches 1 11/4 11/2 2 21/2 3 4 inside width b min 7.85 9.40 12.60 15.80 19.00 25.25 31.55 large standard roller dia roller dia d4 max d1 max 7.95 10.16 11.91 15.88 19.05 22.23 28.58 15.88 19.05 22.23 28.58 39.70 44.45 57.15 all dimensions in mm except as indicated 23 cd contents catalogue selection index transmissions index back next
