actuator 1500 lbs. load
The Motion 85559/85560 Ball Drive Actuator utilizes the Motion Ball Drive 85039 along with a larger series motor and gear reducer than the 85199/85200 to permit Load capacity up to 1500 lb. It also has integral freewheeling at stroke ends to eliminate limit switches. Both 115 VAC and 220 VAC motors are available. The 85559 uses a translating tube for mounting, while the 85560 is an open screw type unit where attachment is made directly to the ball nut. actuator mounts

Ball Drive

Epicyclic Ball Screw 85039 with integral freewheeling at ends of stroke.

Screw OD: .979

Screw root dia.: .843

Advancement/rev.: .281

Centerline pin dimension: 2.343 + stroke

Nut OD: 1.625
Nut mounting: 1 9/16-18 thread.

Materials: heat treated alloy steel with bearing races Rockwell 56C.

Efficiency: 90%

Gear Reducer

Single stage worm gear type with 6008 ball bearing to accommodate ball screw thrust.

Housing: cast aluminum 356 alloy.

Bearings: worm shaft and Ball Drive shaft both supported on sleeve bearing and ball bearing.
Worm and gear materials: steel worm, delrin gear.

Mounting
Dimensions

85559: minimum retracted centerline mounting dimension is 8.100 plus stroke. For example: a 3.500 stroke unit will measure 11.600 (8.100 + 3.500) in the retracted position and 15.100 (11.600 + 3.500) in the extended position. A retracted dimension can be specified greater than the minimum. For example: a 3.500 stroke unit could be 14.000 in the retracted position and 17.500 (14.000+ 3.500) in the extended position. Design options add to the minimum retracted dimension:

Rod end: 2.500

Adjustable stop: 1.250
85560: minimum retracted centerline gearbox mounting hole to nut shoulder is 6.100. For example: a 3.500 stroke unit will measure 6.100 in the retracted position and 9.600 (6.100 + 3.500) in the extended position. A retracted dimension can be specified greater than the minimum. Design options add to the minimum retracted dimension:

Adjustable stop: 1.250

With the alternate nut, the minimum retracted centerline gearbox mounting hole to the centerline of the .375 holes is 6.100 (6.100 + .000).

When the alternate nut is reversed, this dimension will be 4.283.

Weight

85559: 16.8 lbs. (6 in. stroke) 85560: 15.9 lbs. (6 in. stroke)
