This means some amount of gap, or BSE exists between the driver and driven equipment shafts. All Lovejoy Grid Spacer Couplings are supplied with Horizontal Split Covers. The split cover design allows for quick access to the grid spring for ease of maintenance or grid spring replacement. The Horizontal Split Cover is also ideal for applications where there may be some constraints on the diameter of the coupling. Features: ■■Designed for ease of maintenance and grid spring replacement ■■High tensile grid springs ensure superior coupling performance and longer coupling life ■■Split covers allow for easy access to grid springs ■■Interchangeable with industry standard grid couplings Full Spacer Style Half Spacer Style Grid Series Spacer Coupling Performance and Dimensional Data ID1 - ID2 G G1 LTB FD HD OD SL T Nominal Maximum Stnd Set Screw Torque 1 Speed Min Bore Max Bore Hub Location Size Size in-lbs Nm RPM in/mm in mm in in in mm in in in in in 1020 460 48 3,600 Solid 1.38 35 0.19 0.03 1.87 47 3.38 2.06 4.00 0.50 #8-32 1030 1,320 136 3,600 Solid 1.63 41 0.19 0.03 1.87 47 3.69 2.34 4.38 0.31 #8-32 1040 2,200 226 3,600 Solid 2.13 54 0.19 0.03 2.00 51 4.44 3.09 4.62 0.44 #10-24 1050 3,850 395 3,600 Solid 2.38 60 0.19 0.03 2.37 60 4.94 3.44 5.44 0.62 #10-24 1060 6,050 621 3,600 Solid 2.88 73 0.19 0.06 2.50 64 5.69 4.06 5.94 0.44 #10-24 1070 8,800 904 3,600 Solid 3.13 79 0.19 0.06 3.00 76 6.00 4.31 6.38 0.88 1/4-20 1080 18,150 1 864 3,600 Solid 3.50 89 0.19 0.06 3.50 89 7.00 4.81 7.62 0.94 1/4-20 1090 33,000 3 390 3,600 Solid 4.00 102 0.19 0.06 3.87 98 8.25 5.62 8.38 1.03 5/16-18 To calculate the OAL (Over All Length) for Full Spacer Style (Spacer Hubs both ends) use the following formula: OAL = (2 x LTB) + (2 x S) + (2 x G1) + G To calculate the OAL (Over All Length) for Half Spacer Style (Spacer Hubs one end only) use the following formula: OAL = LTB + LTB2 + S + G1 + G www.jbj.co.uk/gridcouplings.html
