ROLLER CHAIN COUPLINGS Stock Coupling Covers Covers allow excellent lubrication, and their use is recommended to obtain maximum coupling life. Covers are of aluminum and are made in halves for easy installation. Synthetic rubber oil seals, which contact the coupling hubs, retain the lubricant and prevent the entry of dirt. Covers are fitted with gaskets between the halves. Stock Coupling Covers Cover Aluminum Cat. No. D 40CC 406CC 506CC 508CC 608CC 600CC 600CC 800CC 4.0.6 4. 4.80 5.9 6..48 8..8.8.4.4 4. 4. 5.08 5.9 t.

Coupling Selection Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accommodate both shafts. For reversing operation, shock or pulsating loads, or other severe operating conditions, select the next larger coupling size. A cover should be used to assure maximum service life, particularly if the coupling operates at high speeds or under moist conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency coupling grease. Recommended Max.
