Answer: Oil lubrication is generally preferable to grease because it is less likely to hold wear inducing contaminants. Except in special high-load, low-speed applications or extended lubrication interval applications, oil is recommended. Please refer to Oil Viscosity Guidelines for Lead Screw Lubrication for specific information.
Answer: It can as long as the screw’s tensile or compressive strength is sufficient to handle the load. For example, the shear strength of a typical C93200 bronze nut with a length equal to twice its major diameter will exceed the tensile strength of a mating AISI 1045 steel screw. In this case, increasing the length of the nut will have no effect on load capacity. On-the-other-hand, the load capacity [...]
Answer: Yes, we offer a variety plating/coating options including black oxide and infused chromium plating. Chromium plating is an excellent choice for low friction, high wear applications especially where lubrication is limited. Precision plating deposition faithfully duplicates thread contours eliminating the edge build or “dog-boning” associated with conventional chrome-plating processes. In some instances, it may [...]
