The pre-load lead screw nut convinces with minimal axial clearance and highest positioning accuracy. It is the cost-effective alternative to the zero backlash lead screw nuts and perfectly suited for small pitches. This is the proven preload principle from SHT-PL.

► Permanently minimal axial clearance for high positioning accuracy
► More cost-effective than ZB nut due to fewer components & injection moulding
► Reduced axial clearance due to spring pre-load on the lead screw nut
► No lubricating grease or oil in the lead screw drive

Reduce the time required for your design and optimise the procurement process for your lead screw technology.
