Load/Life Data Components used in the Simple-Select® range will provide the user with the best combination to achieve a long


and trouble free life in clean or arduous environments. Fitted cap seals cover double row bearings and provide a reservoir for grease lubrication and to prevent dirt ingress. In most cases a single application of grease, which Bishop-Wisecarver provides on assembly of the unit, will last for the life of the machine.


Simple Life Check


Most applications involve central L1 loads. In these cases simply divide your load (N) by the carriage L1 capacity figure below to determine a load factor. Then simply read off the life from the graph. For offset loads you will need to add the relevant load factors to determine the total. Load Factor should not exceed 1.
