K■Selection of L-Balls■LubricationThe static load capacity and maximum operating load For LHSA, lubrication grease (Shell Lubricants Japan of L-Balls are determined in consideration of the K.K. Shell Gadus S2 V125J 2 (S)) is prepacked. LHS strength of the ball stud and the body. Accordingly, is not provided with prepacked grease, so proper L-Balls are selected on the basis of the static load lubrication should be performed.capacity Cs shown maximum operating load shown in Table 3.the dimension table and in the Operating LHS without lubrication will increase the wear of the sliding contact surface or cause seizure.Static load capacityThe static load capacity Cs shown in the dimension table represents the allowable axial force F which is the ball-determined by the mechanical strength of stud at the section 'A' under the bending moment due to the force F as illustrated in Fig. 1. If F increases beyond the static load capacity, deformation will begin at A, leading to breakage.FAFig. 1■Operating Temperature RangeThe maximum allowable temperature for L-Balls is +80℃.■Precautions for Use1 Tightening depth t is recommended that the tightening depth of the screw into the body is more than twice the nominal diameter of thread.2 Allowable tilting angle he allowable tilting angle is shown in Table 4.F′Table 4 Allowable tilting angle VααNominal dia. mmLHSALHSunit: degreeα5-1171819192020212021K48α15171718191920----V 4 5 6 810121416182022Maximum operating loadThe strength of the body must also be taken into con-sideration when L-Balls are operated in a high-tem-perature or low-temperature atmosphere or receive repetitive loads of long duration or shock loads. A guideline for maximum operating load of L-Balls is shown in Table 3. When the xing bolt in the main body is xed and a load is applied in the direction of F′, the bending stress in the xing bolt must be taken into consideration.Table 3 Maximum operating loadunit: NIdentification Maximum Identification Maximum numberoperating loadnumberoperating load 8801 0801 6302 1002 6203 1903 8204 6105 3406 460LHS 5LHS 6LHS 8LHS10LHS12LHS14LHS16LHS18LHS20LHS22 8401 1801 0801 9002 1702 1702 7903 540--LHSA 4LHSA 5LHSA 6LHSA 8LHSA10LHSA10MLHSA12LHSA14--
