Anti-Backlash Nut Block Delrin lead screw TR8x8
Anti-Backlash Nut Block Delrin lead screw TR8x8, is a solid block of Delrin threaded in metric TR8x8 for trapezoidal lead screw.
This block achieves a smooth and precise movement of the shaft, in threaded lead screws.
The block has a tightening screw, to adjust the pressure of this, against the rod and thus avoid the backlash effect (play of the movement). This system achieves a displacement, without looseness, with the intention of having a greater precision in displacement systems that make use of these mechanisms.
The Pass Delrin block nut, is ideal for small CNC machines, the pitch provides good precision and speed, while requiring a minimum of force of a stepper motor, and therefore is suitable for direct drive with small stepper motors Step.
The Delrin nut anti-backlash block is manufactured from grade A Delrin (acetal homopolymer). This material is extremely strong, and normally does not require lubrication. The set screw eliminates any slack, and due to its mechanical properties friction and minimal wear occurs.
For better thread performance, the lead screw should be polished stainless steel, in order to minimize friction and wear.
The most commonly used example is the axes of CNC machines.
The block has two holes 20mm apart for fixing to a plate, base or profile.
