Inquiry (采购产品): R4A Bearing We are designing a "high speed automatic spindle" to be used with a high speed alloy grinder for dental laboratory work. Our competitor is using a R4AZ GMN bearing. We do not know what the ABEC rating is on this particular bearing, but the spindle runs cool. Other bearings that we have tried the spindle runs too hot. We would like to get this exact bearing to try in our spindle. **** Hidden Message ***** John Foster 5421 Commercial Drive Huntington Beach, CA 92649 USA Company: Ray Foster Dental Equipment Phone: 714-897-7795 Fax: 714-898-6013 E-mail: jfoster@fosterdental.com **** Hidden Message ***** jfoster@fosterdental.com
