Dayton DC gearmotor, cylindrical metal body, output shaft visible

Dayton

Dayton M1135235.00 DC Gearmotor 21 rpm 180V TENV 371 in-lb 124:1

SKU CH-YC9S-1N9Z7

Parallel-shaft DC gearmotor delivers 371 in-lb torque at 21 rpm from a 180 V TENV enclosure with 124:1 reduction

  • Delivers 371 in-lb torque for heavy-duty loads
  • 124:1 gear ratio reduces speed to 21 rpm
  • 180 V DC permanent-magnet motor for precise control
  • Totally enclosed non-ventilated housing protects internal components
  • 413 lb overhung load capacity handles radial forces

Industrial Gearmotor for Fixed-Speed Tasks

The Dayton M1135235.00 is a permanent-magnet DC gearmotor rated at 180 volts with a 124:1 reduction that delivers 21 rpm output speed. It produces 371 in-lb of maximum torque from a 1/4 hp input, making it suited for conveyors, lifts and other constant-speed industrial drives.

TENV Enclosure and Flexible Mounting

A totally enclosed non-ventilated housing protects the windings from dust, coolant and debris without requiring external airflow. The unit mounts at any angle and the parallel output shaft sits 4 inches high with a 3/4 inch diameter, while heavy-duty ball, needle-roller and thrust bearings handle up to 413 lb of overhung load.

Bidirectional Rotation and Ready-to-Install Shaft

The motor runs clockwise or counter-clockwise straight from the supply, so no extra reversing circuitry is needed for basic automation. The hardened output shaft accepts standard keys and couplings, and the sealed bearing package eliminates the need for periodic lubrication in most duty cycles.

Questions about this item

What does the 180 V DC rating mean for speed control?

The motor runs on 180 V DC; speed is set by the applied voltage and the fixed 124:1 gear ratio, giving a nameplate speed of 21 RPM at full voltage.

What mounting footprint and shaft size does the 4 in output shaft height and 3/4 in diameter require?

The unit mounts at any angle with a 4 in shaft centre height and a 3/4 in diameter output shaft; match your mounting surface and coupling to those dimensions.

How do I wire the motor for reversible CW/CCW rotation?

Swap the two DC supply leads to reverse rotation; the permanent-magnet design runs CW or CCW depending on polarity, with no extra wiring steps needed.
