Dynamic basic load rating ofantifriction bearing rod ends DURBAL heavy-duty rod endswith integral self-aligning roller bearings,Series BRTM,BRTF

The dynamic basic load rating C of anantifriction bearing rod end is the external radial load, unchangeable in size and direction, at which 90 % of astatistical sample of identical rodends will reach or exceed 1 million of rotations or swiveling movements. initial lubrication, we recommendlubricating with a calcium-complex- soap-grease or Polyrex EP2 A Greas e nipple .Shields on both is provided for lubrication in case of roughoperation and maximum load. To avoid incompatibility with the at ing mo tion with medium loads.Compared to rod ends with self-aligning ball bearings, rod ends with self- aligning roller bearings have essentially higher basic load ratings.This design isequipped with a cage to minimize the rolling friction and heat built-up.These rod ends are under normal operating conditions maintenance-free. The design based on the structure of aself-aligning roller bearing is preferably used for high speed, large tilting angles or rot

Dynamic basic load ratings ofplain bearing rod ends

The dynamic basic load rating C is theparameter for the calculation of dynamically loaded maintenance-free DURBAL heavy-duty rod ends with integrated spherical plain bearing, inother words, making tilting, swiveling or rotating movements under load.Basic load ratings always depend on thedefinitions they are based on.For this reason it is not always possible to compare basic load rating data suppliedby different manufactures. DURBAL heavy-duty rod ends are sturdy, sides prevent dirt particles from penetratinginto the bearing.The rod ends with self-aligning roller bearings are, just as the design with self-aligning ball bearings,subjected to a special heat treatment procedure to match the racway hardness to the antifriction bearings, ensuring at the same time a high stability with changingloads and temperature
