Professional Applications & Engineering Value
This threadless lead screw nut is engineered for precision linear motion systems where smooth operation and high thrust capacity are critical. The two-piece aluminum construction combined with 6 ball bearings minimizes wear and provides consistent performance in automation, CNC machinery, and positioning equipment. The thrust adjustment bolts allow operators to compensate for backlash, maintaining accuracy over extended use. With a temperature range of -10° to 180°F and lubricated design, it performs reliably in fluctuating industrial conditions, reducing maintenance needs and enhancing machine uptime. Ideal for applications requiring repeatable motion control with minimal friction.
Specification Summary & Compliance
Manufactured to inch system standards with UNC thread specifications for mounting holes (1/4"-20). The nut features precise dimensional tolerances, including overall length of 3 27/64", width of 2", and center height of 1 1/64". Compliant with industry standards for linear motion components, ensuring interchangeability and performance in industrial lead screw assemblies. Materials and construction adhere to common engineering specifications for durability and operational safety.
