Non-PTO accessories include adaptors, splined shafts, couplings, bushings, hubs, and overhung load adapters for hydraulic motors.

Provide a means to add a square bushing coupling by welding to a shaft

Provides an economical repair option for repairing worn parts on a transit-mixer

Provide a means to couple two straight spline shafts together. Machinable and weldable

Provide a means to couple two involute spline shafts together. Machinable and weldable

Designed especially for fluid power applications. Adapts a smaller splined shaft to a larger splined bore.

Straight splined shafts available from 1”- 6 spline to 1-3/4” 6 spline, 10” long. Machinable and weldable.

Straight splined shaft extensions available from 1-1/8”- 6 spline to 1-3/8” 6 spline, 9” long. Machinable and weldable.

Involute splined shafts available from 5/8”- 9 spline to 2-1/8”” 16 spline, up to 10” long. Machinable and weldable.

  • Use to join two shafts
  • Repair pulleys, gears, sprockets, etc.
  • O.D. and I.D. concentricity not held to close limits
  • If precision O.D. and I.D. concentricity is required, write for quotations
  • Not drilled for setscrews


  • Designed for hydraulic motors
  • Made from low alloy, high carbon steel
  • Close tolerance O.D. and I.D. concentricity permits accurate mounting of sheave or sprocket
  • Precision also permits accurate chucking for additional mounting

  • Same construction as Standard-Duty Tractor Models
  • For those applications other than tractor P.T.O. shafts, where the driven shaft overruns the driver occasionally or where one shaft must override or idle part of the time.
  • Operating Speed to 1000 RPM

  • Same construction as Standard-Duty Tractor Models
  • Universal flange for mounting sheave or sprocket, has six 3⁄8” holes equally spaced on 4 1⁄4” Bolt Circle.
  • Flange O.D. 5” – Hub O.D. 2 3⁄4”
  • Operating Speed to 1000 RPM

Send us details of your special requirements! We can design and manufacture to your order. Pictured to the right is a special unit with sprocket welded to outer housing.

  • Cast iron segments for durability
  • Rigidly attached spring with contoured handle permits installation and removal with one hand
  • Universal: each segment assembly fits all shaft sizes 1 through 1 3⁄4 inches

Specifically designed to direct connect with the Orbit motor and provide substantially greater capacity for sprockets, sheaves, etc..

  • Tapered Roller Bearings
  • Grease Seals
  • Lubricated for Life
  • Two (2) Shaft Sizes
  • Maximum O.H.L. Capacity

With the HUB CITY Series 330 Pump Drive, it is now possible to increase either 540 RPM or 1000 RPM tractor P.T.O. speed to 1825 RPM to permit use of a similar, less expensive hydraulic pump for your implements. Two flange sizes are available: SAE B and C, for use with standard SAE pumps. Also, both spline and round shafts are available in several sizes to suit your pump adaptation requirements

  • Two standard ratios available
  • Increases 540 or 1000 RPM tractor P.T.O. speed to 1825 RPM to facilitate use of a smaller, less expensive hydraulic pump
  • Fits most standard SAE hydraulic pumps having SAE B or C mounting flange
  • Rated for pumps requiring up to 45 HP at 540 RPM and 65 HP at 1000 RPM
