Rexnord 1040T Coupling

Rexnord 1040T is a close-coupled grid coupling in the Rexnord T10/T20/T31 family, sized for direct motor-to-driven equipment connections. It delivers a torque rating of 2,200 in-lbs (249 Nm) and supports maximum speeds of 4,500 rpm (T10), 6,000 rpm (T20), and 3,600 rpm (T31). The unit's published performance includes a kW per 100 rpm of 0.026, suitable for moderate torque transfer in compact installations. The 1040T uses Rexnord's grid element technology, which accommodates small shaft misalignment and torsional fluctuations to maintain smooth torque transmission. Its close-coupled T10 configuration is designed for tight shaft spacing, enabling straightforward alignment and installation in compact systems. Common applications include electric motor or turbine-driven equipment such as pumps, blowers, and compressors that require reliable, space-efficient power transfer. General installation guidance and hub compatibility are available from Rexnord catalogs and product sheets for the 1040T family.
