59. For long trouble free bearing service the bearing loads should not exceed about 200 psi Standard cylinders are not designed for heavy eccentric loads The use of oversize rods to reduced bearing loads is not recom Column Strength Considerations Standard size rods are recommended for use in cylinder applica tions where column strength rod sag or rate of cylinder return do not require an oversize rod Being more flexible standard rods absorb shock loads and minimize bearing loads caused by misalignments PSS Z mended They are not as effective as stop tubes and if misalign ment occurs the additional rod stiffness will actually increase bearing loads For long push stroke cylinders a stop tube may be required to limit radial bearing loads to a safe value and prevent jackknifing They are especially desirable in long stroke pivoted centerline style mountings The effect of a stop tube may be duplicated by providing additional unused stroke and stopping the cylinder extension by external means Cylinder jackknifing For long push stroke cylinders an oversize rod may be required to prevent column failure and rod bending Total cylinder length extended is considered in column strength Refer to the tables on the following pages for calculations regarding the column strength and stop tube required for a cylinder application Rod bending 167 38 72 Bosch Rexroth Corp Industrial Hydraulics Model CDT4 CGT
