A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
A lead screw uses direct sliding contact between the nut and threads, while a ball screw uses recirculating balls to reduce friction. Ball screws offer higher efficiency and lower backlash but may require more maintenance.
Determine required load, speed, accuracy, and environmental conditions. Refer to the reference ranges for diameter, lead, load ratings, and accuracy grade, then verify with the manufacturer for the specific model.
C3 indicates higher precision, suitable for applications requiring tight positioning accuracy, while C7 is for general use. The grade affects the allowable lead error over a given travel length.
Regular lubrication with grease or oil as specified, periodic inspection for backlash and noise, and checking for wear. Replace if backlash exceeds acceptable limits or if damage is detected.
