Acme Lead Screws and Nuts
Acme Lead Screws and Nuts
Acme threads have a trapezoidal shape, which offers better load-bearing capabilities and smoother operation compared to standard triangular threads.
Metric Lead Screws and Nuts
Metric Lead Screws and Nuts
Metric lead screws and nuts are similar to Acme screws but use metric dimensions and standards. They are commonly employed in various linear motion applications that require precise movement and high load-bearing capabilities.
Precision Acme Lead Screws and Nuts
Precision Acme Lead Screws and Nuts
Precision lead screws are manufactured with very fine tolerances, resulting in high positioning accuracy, often with leads accurate to ±0.001" or better.
Fast-Travel Precision Acme Lead Screws and Nuts
Fast-Travel Precision Acme Lead Screws and Nuts
Fast-Travel Precision Acme Lead Screws and Nuts are specifically designed to offer both speed and precision in linear motion applications. These components provide rapid linear movement with minimal rotation of the screw, making them ideal for systems that require quick positioning without sacrificing accuracy.
Metric Precision Lead Screws and Nuts
Metric Precision Lead Screws and Nuts
Metric Precision Lead Screws and Nuts are designed for applications requiring highly accurate linear motion and comply with metric standards, making them ideal for use in global markets.
Ultra-Precision Lead Screws and Nuts
Ultra-Precision Lead Screws and Nuts
Ultra-Precision Lead Screws and Nuts are designed for applications that demand the highest level of accuracy, repeatability, and smooth linear motion. These components are used in industries where extreme precision is critical, such as aerospace, medical devices, scientific instruments, and advanced manufacturing.
Fast-Travel Ultra-Precision Lead Screws and Nuts
Fast-Travel Ultra-Precision Lead Screws and Nuts
These lead screws typically feature a trapezoidal or modified Acme thread profile, but with a coarser pitch, allowing for faster travel per screw rotation. The ultra-precision nature means they are manufactured to extremely tight tolerances for high accuracy, even at high speeds.
Metric Fast-Travel Ultra-Precision Lead Screws and Nuts
Metric Fast-Travel Ultra-Precision Lead Screws and Nuts
Metric Fast-Travel Ultra-Precision Lead Screws and Nuts offer the ideal combination of speed, accuracy, and adherence to global metric standards.
Metric Ultra-Precision Lead Screws and Nuts
Metric Ultra-Precision Lead Screws and Nuts
These nuts are designed with tight tolerances to match the precision of the lead screw. Common materials include bronze, brass, and advanced polymers like Delrin or PTFE. The choice of material depends on the application’s specific needs, such as load capacity, friction, and wear resistance.
Clamping Acme Lead Screw Collars
Clamping Acme Lead Screw Collars
Clamping Acme Lead Screw Collars are used to secure Acme lead screws in place while allowing for easy adjustment and repositioning.
Two-Piece Clamping Acme Lead Screw Collars
Two-Piece Clamping Acme Lead Screw Collars
They typically come in two halves that clamp around the lead screw, providing a more adjustable and versatile solution compared to single-piece collars. This design allows for easy installation and adjustment without needing to remove the lead screw.
Metric Clamping Lead Screw Collars
Metric Clamping Lead Screw Collars
Metric Clamping Lead Screw Collars are mechanical components designed to secure lead screws or other shafts in place along a linear axis. These collars use a clamping mechanism to grip the lead screw securely without damaging its surface.
Self-Reversing Lead Screws and Nuts
Self-Reversing Lead Screws and Nuts
The nuts used with self-reversing lead screws are designed to follow the unique thread profile, enabling them to smoothly reverse direction when reaching the end of their travel. These nuts are made from materials like bronze, brass, or low-friction polymers such as Delrin or PTFE.
Threadless Lead Screw Nuts
Threadless Lead Screw Nuts
Instead of using threads, a threadless lead screw has a smooth or grooved surface. The nut, which is the moving component, grips the lead screw through friction, allowing for linear motion as the screw rotates.
