14 moves the reaction force from this equipment is approximated as a vector and illustrated by arrow 20 in fig1 as can be seen the force illustrated by vector 20 has a vertical component 22 as shown in fig2 the vertical component 22 acts as a force acting downwardly on the piston rod 14 fig2 is a cross sectional view of hydraulic cylinder 10 the hydraulic cylinder 10 may include an inlet outlet 16 and 18 and internal bore 24 within the cylinder housing 12 set within the internal bore 24 is a piston 26 the piston 26 is attached to the piston rod 14 the piston rod 14 is supported in part by the piston 26 and a rod bearing 28 the vertical force component 22 may generate reactionary force components illustrated as force arrows 30 and 32 in fig2 and 3 fig3 is an enlarge partial cross sectional view of the cylinder housing 12 containing the piston 26 and piston rod 14 located within internal bore 24 inlet outlet 18 is also shown the reactionary force arrows 30 and 32 indicate where reactionary forces may be generated to keep the piston rod 14 piston 26 located within the internal bore 24 these reactionary forces 30 and 32 may urge against the wall 34 of the internal bore 24 the piston rod 14 the piston 26 and the rod bearing 28 creating wear points 36 and 38 as the hydraulic piston 26.
