This QIBR training video is about the application mounting and dismounting of cylindrical roller bearings Note: the video has speaker text in English and is subtitled QIBR cylindrical roller bearings QIBR bearings and maintenance tools used in this video Note: Some of the tools have been upgraded or replaced by newer versions
Cylindrical roller bearings are the most basic type of roller bearing and use rollers instead of balls as a rolling element These rollers are slightly crowned and have a greater length than width Most cylindrical roller bearings are single row with a cage that houses and spaces the rollers
2017-8-7Dismounting of Bearings with Cylindrical Bores If the mounting design allows space to press out the inner ring this is an easy and fast method In this case the withdrawal force should be imposed only on the inner ring (Fig 12) Withdrawal tools like those shown in Figs 13 and 14 are often used
When mounting cylindrical or needle roller bearings with an inner ring without flanges or with a flange on one side only a guiding sleeve should be used The outside diameter of the sleeve should be the same as the raceway diameter of the inner ring and should be machined to tolerance class d10Ⓔ for cylindrical roller bearings and to
seal Carrier Assemblies are screwed to the centre washer of needle roller/axial cylindrical roller bearings and precisely centred there They seal the bearings from the outside The sealing elements are supplied as a complete set and comprise a seal carrier with an integral rotary shaft seal a gasket and socket head cap screws for mounting the carrier on the centre washer of the bearing we
2020-8-19Mechanical dismount of bearings is carried out with an extractor Extraction is required on the tight ring The choice of extractor depends on: the diameter: to define the scope spacing and the force required for extraction the accessibility: external internal or special the method of extraction: choice of fulcrum from the center line of the shaft or the exterior or using extraction
Most of cylindrical roller bearings are designed with separable inner ring or outer ring which is easy for mounting and dismounting The ribs of UBC cylindrical roller bearings have optimized design and are specially processed for improved lubrication and reduced
2015-6-11Compared with ball bearings cylindrical roller bearings etc these bearings have a large number of rolling elements the elements being long so there is a little elastic deformation and high rigidity The pitch of their rolling elements is relative small so it makes these bearings ideally suited to handle oscillating movement
The first video on this page is an introduction to QIBR rolling bearings Below you can choose to view the training video for the mounting and dismounting of specific bearing types Note: Some of the tools have been upgraded or replaced by newer versions All videos have speaker text in English and are subtitled
