A wide range of fittings enables themto be used with various clips are available for most designs- See pages 32 & ball units are available in various materials. The material required for yourball units should be quoted when ordering(see table below).LLuubbrriiccaattiioonnEach unit is pre-lubricated during manufac-ture and normally does not require furtherattention. In certain instances we will adviseon lubrication. Greasing or oil points can beincorporated in some suitable cleaning or release fluid should beused in dirty conditions. For washing, a suit-able detergent such as paraffin; for freeing,a suitable agent such as WD40 - pleaseconsult technical designs have dirt exit holes incorpo-rated in the bearing cup, or these can beadded on llooaaddssWhen calculating loads, consider the possi-bility of impact caused by incorrect loaded units will reduce wear andtear if there are regular shock loading can also be reduced by fittingcompressible units can also be made retractable byother means, such as pneumatic orhydraulic cylinders, cams or levers.
