This keyed clamp style double insert type hub requires the user to mate it with one other hub and two acetal inserts. The multiple piece construction allows for a highly customizable coupling that easily combines clamp hubs with inch, metric, keyed, and keyless bores. This hub has a 30mm bore, 8mm keyway, 75.0mm OD, and 18.0mm length. The use of a keyway prevents the coupling from slipping on the shaft if over torqued. This double insert type has higher torque capacity than single insert styles. It is longer than equivalent single insert Controlflex types to couple systems with wide distances between shaft ends. It has a balanced design and can accommodate speeds of up to 7500 RPM.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv class=\"nbs-spec-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;\"\u003e\u003ctable class=\"nbs-spec-table\" style=\"width:100%;max-width:100%;border-collapse:collapse;font-size:0.95em;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:8px 10px;border:1px solid #d9dee5;background:#f4f6f9;width:38%;\"\u003eBrand\u003c\/th\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #d9dee5;\"\u003eRuland\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;padding:8px 10px;border:1px solid #d9dee5;background:#f4f6f9;width:38%;\"\u003eManufacturer Part Number\u003c\/th\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #d9dee5;\"\u003eMCPRDK75-30-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv class=\"nbs-b2b-callout\" style=\"border-left:4px solid #1F3A5F;background:#f4f6f9;padding:12px 16px;margin:18px 0 0;\"\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eOEM Part Verification:\u003c\/strong\u003e Confirm Ruland part number MCPRDK75-30-A against your equipment nameplate or parts list before ordering.
