| Slide Load Capacity To optimize slide operation over the long haul, one of the most important considerations in selection is the loading applied to the slide. Loading capacity is based on the pressure exerted by an externally applied load on the engaged slide way surfaces. These externally applied loads are considered to be the following: • STATIC Loading - External loading is applied to a stationary saddle. • DYNAMIC Loading - External loading is applied to a moving saddle. • SINGLE Loading - Only one external load is applied. • COMBINED Loading - More than one external load is applied. The recommended maximum load and moment capacities can be determined from the "Slide Load Capacity Chart." Use the data only as a guide to determine the proper size slide for a particular application. The values in the chart are based on a way surface bearing pressure of 50 psi. However, this pressure may be adjusted to suit your application using the following guidelines: • Use 50 psi for: - Manual feed slides. - Manual lubricated slides. - Slides used for precision machining and grinding applications. - Slides subjected to combined loading. • Use 100 psi (multiply values in chart by 2) for: - Power feed slides. - Slides having forced lubrication. - Slides used for rough machining and positioning applications. - Slides subjected to single loading. • Use 500 psi (multiply values in table by 10) for: - Slides subjected to static loading. Coefficient of Friction • 0.10 as standard. • 0.05 with forced lubrication. |
