Norco's Miniature Rollnut Actuator Is A Small Wonder For Medical Applications
RIDGEFIELD, CT - Norco, Inc., a leading manufacturer of custom-designed mechanical devices, offers its Miniature Rollnut lead screw actuator for precision medical devices.
The Miniature Rollnut is a lead screw actuator that converts rotary motion to linear motion or vice-versa. It is designed for use in small applications that require precise, repeatable insertion and withdrawal. Norco's Miniature Rollnut has been utilized for a variety of medical device applications from drug delivery systems to laboratory analyzers.
Norco's Miniature Rollnut is different from conventional ball screws and nuts because a roller rides in a thread groove instead of a ball, resulting in line contact, not just point contact, with the shaft. This allows for smooth transportation of pipettes, syringes, or well plates. The roller assembly consists of a hardened, ground tapered roller rotating in sealed, lifetime-lubricated ball bearings. Coupled with the use of dry lubricant surfaces in the thread grooves, this lifetime-lubrication results in virtually maintenance-free operation.
The Miniature Rollnut is designed for durability under harsh conditions including dirt, dust, moisture, radiation, high vacuums, etc. The nut assembly has centralizing bearings at both ends, allowing it to tolerate side loads and assuring accurate alignment.
Also, like Norco's other power transmission products, the Mini Rollnut can be easily customized to meet the specific requirements of practically any application. Norco's design team can specify a Mini Rollnut with nearly limitless design configurations. Custom designs can accommodate materials of any type, including stainless steels and alloys, plastics, fiberglass, and another sophisticated compounds. Designs can also be combined and assembled with a variety of timing belt drives, sprockets, pulleys, and other mechanical apparatus such as locking and coupling devices, struts and supports, and electromechanical drives.
