Frequently Asked Questions
What is a chain coupling?
A chain coupling connects two shafts through two sprockets wrapped by a double-strand roller chain. The design is simple and robust, transmits high torque at low speed, and tolerates minor shaft misalignment.
Does a chain coupling need lubrication?
Yes. Regular lubrication is required for good performance and service life. The spec sheet lists a cover for sizes up to 20022; larger sizes are supplied without a standard cover.
How do I read a chain coupling size number?
The last two digits are the number of sprocket teeth and the digits before them are the chain pitch code. Size 4016, for example, uses 12.70 mm (1/2 in) pitch chain on 16-tooth sprockets, and 10020 uses 31.75 mm (1.25 in) pitch on 20-tooth sprockets.
Where are chain couplings used?
Typical applications are conveyors, cranes and hoists, mixers and agitators, steel and rolling mills, and heavy-duty power transmission. The design suits harsh and dirty conditions such as mining, steel and material handling.
What should I send for a chain coupling quote?
Send both shaft diameters and keyways, the motor kW and rpm, and the application, and SMI's engineers come back with the size. The sizing method is: torque T (Nm) = 9550 × kW ÷ rpm, multiplied by a service factor for the load, then a size whose torque rating and bore range cover the result.
Is Super Mech Industries a chain coupling manufacturer or a trader?
A manufacturer. Chain couplings are made at SMI's factory in Odhav, Ahmedabad, Gujarat, which is ISO 9001:2015 certified (Certificate No. 09114716A). SMI also makes chain sprockets.
What sizes of Chain Coupling does SMI manufacture?
SMI lists 24 sizes from 3812 to 40028 rated from 99 Nm to 717,000 Nm, with bores finished up to 670 mm. The full size chart with dimensions is on this page and on the spec sheet.
