3504 Series Lead Screw Clamping Collar (8mm Lead, 4 Start, 21mm OD, 9mm Length)


The bore of this 8mm lead screw clamping collar matches the threads of an 8mm, 4 start lead screw to provide maximum clamping force when the pinch bolt is tightened down.  A lead screw collar is commonly found in linear motion assemblies where the lead screw is held in a bearing or pillow block and it’s necessary to restrict the lead screw from moving axially.
