AlgapotPN -Fixed bearings

Algapot PNm-Free sliding bearings

Design concept is mainly given by a rubber disk (1)

AlgapotPNu -Sliding guided bearings

completely enclosed into a steel pot shaped frame formedby a steel basement (2) with pot shaped seat fitting therubber disk and by a steel lid (3) protruding with a smalltolerance inside the pot.The rubber disk allows mutual rotation in any directionbetween pot basement and lid and can support verticalloads with negligible deformation.The rubber disk into the pot is subjected to uniform three-axial pressure and into behaviour is the same of anincompressible liquid inside a cylinder.The horizontal forces are directly transmitted from the lidto the pot basement.

They are similar to the previous ones with an additionalupper PTFE disk (4) and an additional sliding steel plate(5) with stainless steel plate (6) covering the lower surface,so that horizontal movements in any direction are allowed.

They are similar to the previous ones with an additionalguide (7) which defines the direction of the movement andsupports horizontal forces perpendicular to itself
