1 PILLOALL Spherica ushins - Insert PILLOALL Ro Ens - Insert PILLOALL Ro Ens - ie-cast PILLOALL Ro Ens - Maintenance-free Structure an Features PILLOALLs are compact sef-ainin spherica bushins that can support a are raia oa an a bi-irectiona axia oa at the same time. These bushins are cassifie by siin surface types, namey, insert type, ie-cast type an maintenance-free type. In the insert type, a spherica inner rin makes contact with the specia copper aoy bushin with superior run-in properties. In the ie-cast type, a spherica inner rin makes irect contact with the bore surface of the boy of specia zinc ie-cast aoy. In the maintenance-free type, a spherica inner rin makes contact with the specia PTFE iner of maintenance-free type. Thus, a smooth rotationa an osciatory motion can be achieve with superior anti-wear an oain properties in each type. PILLOALL Ro Ens have either a femae threa in the boy or a mae threa on the boy, an they can be easiy assembe onto machines. PILLOALLs are use in contro an ink mechanisms in machine toos, textie machines, packain machines, etc. The maintenance-free type is especiay suitabe for oain in one irection an is the best choice for machines in which oi must be avoie such as foo processin machines, or machines which cannot be re-ubricate.

Lubrication PILLOALL Ro Ens Insert PHS A), POS A),PHS an POS This type has superior wear-resistant an corrosionresistant properties as we as hih riiity. It consists of a spherica inner rin of which the spherica surface is chromium pate after heat treatment an rinin, a boy with a zinc chromate pate outer surface, an an inserte bushin of specia copper aoy havin superior run-in properties. PHS, which has a femae threa in the boy, an POS, which has a mae threa on the boy, are avaiabe. For PHS an POS sizes to, an A is appene after the imensions as a moe coe. Lubrication PILLOALL Ro Ens ie-cast The spherica inner rin of this type is mirror-finishe after heat treatment an is buit in a boy of specia zinc ie-cast aoy. The siin surfaces of the inner rin an boy are in cose contact with each other. Thus, this type is an economica ro en with superior anti-wear an oain properties. Maintenance-free PILLOALL Ro Ens PHS EC,POS EC This type has superior anti-corrosion properties as the boy is zinc chromate treate an the spherica inner rin is chromium pate on the sphere surface after heat treatment an rinin. A specia PTFE iner, reinforce with copper aoy meshes, which is superior in anti-wear properties with itte creep eformation is use for inin on the siin surface of the boy, an this type is maintenancefree. PHS EC, which has a femae threa in the boy, an POS EC, which has a mae threa on the boy, are avaiabe.

Thus, a suitabe type an size shou be seecte base on the ynamic oa C an static oa shown in the imension tabes. Loa ynamic oa The ynamic oa C is obtaine on the basis of the contact pressure on the siin surface. The ynamic oa is use for cacuatin the ife. The ynamic oa consierin temperature increase is obtaine from the foowin equation usin the temperature factor, which is a correction factor for the effect of PILLOALL temperature.
