Precautions To Be Taken if an Eccentric Load Is Applied
Model LG achieves a much higher load-carrying capacity in receiving the eccentric load (moment and torque) than Linear Bushing model LM because of 4 rows of raceways. However, under conditions where the eccentric load is larger, the product may result in poor operation or early failure.In such cases, we recommend using Ball Spline model LBS or LT, both of which have larger loadcarrying capacities ( see onward for model LBS , or onward for model LT ).
