Premium Stainless Steel Feeler Stopper for Nidek ME, LE & LEx Series
Protect the delicate measurement system of your optical equipment with our high-quality Feeler Stopper. Engineered as a direct, brand-new replacement for OEM reference 40340-M985, this essential mechanical stop ensures repeatable positioning and prevents over-travel of the feeling unit, safeguarding your edger’s accuracy.
Because the feeling mechanism operates in a constantly wet and demanding laboratory environment, standard metals are prone to rust and degradation. Our replacement stopper is manufactured entirely from premium stainless steel (Inox) for ultimate corrosion resistance and mechanical strength. For your convenience and an immediate installation, this part is supplied with two matching stainless steel screws.
