[ ! ]EBC, EBSZ, EBBC and EBHZ use low particulate grease and the resin section may be discolored due to reactions with ultraviolet, but the functionality will not be affected.
[ ! ]Surface resistivity of antistatic polyacetal is 1.5x10¹¹Ω (Temperature 23°C / Humidity 65%)
[ ! ]For identification, markings are painted on the side of antistatic polyacetal plastic parts. Wipe off before use.
*SUJ2 equivalent materials are used in some products. Please check the product specifications and dimensions when selecting a product.
