Mechanical Power Transmission Bearing Supported Stub Shafts www.jbj.co.uk/bearing-supported-stub-shafts.html 2 #DriveLineHarmony This stub shaft design employs a single and double roll radial ball bearing designed for light and heavy-duty work, not to exceed side loads listed in tables 1 to 4 on the following page 3. The bearings are self-contained in our specially designed housing that will keep the assembly free of contamination. These supported stub shafts come pre-mounted to your specific flywheel housing plate or custom housing. The package includes a mounted bearing support and flywheel coupling that will be sized to your application to drive the bearing support sub-assembly. We emphasize that the data contained herein should be used as a guide only. The tabulation is based on laboratory tests but does not take into account all variables that can be encountered in actual use. All applications are individual, no two are identical in setup or environmental conditions after all. Therefore, it is advisable to test the material under actual service conditions before specification. If this is not practical, tests should be devised that simulate your service conditions as closely as possible. Important Note: The bearing support must be greased every 2000 hours to ensure bearing life. Specifically designed for side load applications. Output: Depends on your application for shaft size and length. Ratings: Input torque (max.): 881 Nm (650 lb-ft). Input / output speed: 3000 rpm. Power (Max.): 261 kW (350 HP). Bearings: 3 years continuous running. 76.2 mm (3") or 127mm (5") 36.5 mm (1⁷⁄ ") 38.1 mm (1¹⁄ ") 50.8 mm (2") 63.5 mm (2¹⁄ ") Splined coupling to drive stub shaft Grease fill Heavy duty double row bearing Depends on shaft diameter and length Depends on shaft diameter Relief valve
