• Use a 4-5 times safety factor for static and moment loading (10 times if you actually will be doing work i.e. gluing, routing, etc. while the load is moving)
• If you use two blocks on one rail you can double the direct load carrying capability and the Mr (roll) moment capability of a single block. You can also use a factor of 5 times the Mp (pitch)
  and My moment loading capability of a single block
• If you use two parallel rails/w one block each you can double the load carrying capability and the Mp (pitch) moment as compared to using one rail and block. You can also use a factor of 5 times the Mr (roll) and My moment loading capability of a single block and rail
• The Basic Dynamic Load Rating heading is a figure that says "90% of all identical guideway/bearing combinations will have a life of 50 km (31 miles) of travel at this load."
  

• Kgf (kilograms of force) x 2.2 = pounds
• 1 kN-m (HG) = 1000Nm = 102 Kgf-m = 737.56 foot pounds
• kN-m x 737.56 = foot pounds
• Kgf-m (kilograms of force per meter) X 7.233 = foot pounds
• kN x 224.81 = lb
• N x .225 = lb
• Inches x 25.4 = mm (millimeters)
