Zero-Max Linear Actuators
The Roh’lix® Linear Actuator is a device that converts rotary motion into linear motion. The Roh’lix uses rolling element ball bearings that trace a helix pattern along the shaft, which produces a Rolling Helix, or Roh’lix for short.
Available sizes have thrust capacities ranging from 5 to 200 lbs (67 to 889 Newton’s), shaft diameters ranging from 3/8 to 2.00 inches (8 to 50 mm), and leads ranging from 0.025 to 6.00 inches (0.625 to 150 mm).
Features and Benefits:
- Choose from 5 different sizes, a wide range of leads and various shaft diameters to find the right one for your application.
- Easy installation. The 2-piece split aluminum block can be assembled around the shaft without necessitating the removal of driveshaft and/or pillow-block bearings.
- Roh'lix has the ability to slip in the event of a jam-up, protecting product equipment.
- Adjustable thrust setting can be set precisely to carry the load without slipping, but not so high that the Roh'lix builds up unnecessary thrust before overloading.
- Roh’Lix Linear Actuators are extremely efficient (over 90%). Long life which ranges from 2 million to 10 million inches of linear travel.
- Coil springs for thrust adjustment. Preloads bearings to minimize backlash to less than 0.001 inch. Minimal backlash stays consistent throughout the lifetime of the unit.
- Socket-head shoulder screws to mount the bearings to the block allows for easy bearing replacement.
- Roh’lix bearings are factory-lubricated for life and are designed to run on a clean, non-lubricated driveshaft.
- Acceptable temperature range is -10°F to +180°F. Special units available for higher or lower temperatures.
- Unit is maintenance free; however, the shafting may require occasional wiping to clean off foreign matter that may accumulate
- Two Roh’lix may be used in tandem on a common shaft in series, or on separate shafts in parallel, however, the combined thrust rating must be derated by 20%.
