This second output enables simultaneous drive of two independent loads from a single gearbox &mdash; a primary application drive via the main output bore and a secondary auxiliary drive (encoder, tachometer, small pump, or fan) via the tail shaft.<\/p>\n<\/div>\n<div style=\"width:100%;max-width:400px;box-sizing:border-box;background:#fff;border:1px solid #D8DCE3;border-top:4px solid #E8A020;border-radius:6px;padding:3%;\">\n<h3 style=\"color:#1B3F6E;font-size:clamp(15px,2vw,18px);margin-top:0;\">&#128674; Heavy Chain + Crane Position Feedback<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">At 7.5 kW chain input with 12,000 N radial load capacity, the NRV-E110 is the standard choice for instrumented crane chain drives requiring both heavy chain power transmission and precise encoder position feedback.<\/p>\n<\/div>\n<div style=\"width:100%;max-width:400px;box-sizing:border-box;background:#fff;border:1px solid #D8DCE3;border-top:4px solid #2E9E6B;border-radius:6px;padding:3%;\">\n<h3 style=\"color:#1B3F6E;font-size:clamp(15px,2vw,18px);margin-top:0;\">&#9711; Same Torque as Standard NRV110<\/h3>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;\">The NRV-E110 delivers identical maximum output torque (9,232 N&middot;m) to the standard NRV110, confirming that the tail shaft adds zero performance penalty on the main output.

The shaft diameter matches the equivalent NMRV110 bore input diameter. It accepts chain sprockets, belt pulleys, and rigid couplings. A bilateral (double-ended) input shaft is standard; single-end configuration available on request.<\/p>\n<\/details>\n<details style=\"border:1px solid #D8DCE3;border-radius:6px;margin-bottom:10px;padding:3%;\">\n<summary style=\"font-weight:bold;color:#1B3F6E;font-size:clamp(14px,2vw,17px);cursor:pointer;\">What encoder types can be mounted on the NRV-E110 tail shaft?<\/summary>\n<p style=\"color:#3A3A3A;font-size:clamp(13px,1.8vw,16px);line-height:1.7;margin-top:10px;\">Any standard keyed rotary encoder with the matching bore diameter can be mounted on the NRV-E110 tail shaft: incremental (5V&ndash;24V, 100&ndash;10,000 PPR), SSI absolute, or resolver-type.

The NRV-E110 is the ideal solution for chain-driven systems requiring closed-loop speed feedback. The chain drives the solid input shaft; the main output drives the load; and the tail shaft mounts an encoder that feeds speed\/position data back to the controller.
