allowable axial load for cylindrical roller bearings

Computational assessment of the allowable static contact

May 01 2015Roller bearings in general have larger typical load carrying capabilities at given nominal diameters which is also true for large roller-slewing bearings However when dealing with the contacts of rollers with bearing raceways attention is required for dealing with detailed roller geometries and their influences on the subsurface stress

Cylindrical Roller Bearings High axial load carrying

capacity and high rigidity In addition to high radial loads cylindrical roller bearings can also support axial loads if they are used as semi-locating or locating bearings Whereas radial loads are transferred via the raceways axial loads are transferred via the rolling element end faces and ribs which of course limits the axial load

Tapered roller bearing load ratings versus performance

Nov 01 2018where C r = basic dynamic radial load rating b m = rating factor of bearing type (value 1 1 for tapered roller bearings) f c = material/geometry/dimension factor i = number of rows L we = effective roller length = contact angle Z = number of rollers per row D we = mean roller diameter The relevance of fc as performance factor is very obvious for example a performance factor of 1 23 results

Dodge Bearings: Effects of Axial Loading on Fatigue Life

WP0255 2 As seen in Table 1 below each size of bearing has two distinct sets of load factors The choice between the two sets of values is determined by comparing the ratio of axial and radial load to the value e The e value is the point at which the axial load begins to shift the rollers to one side of the raceway and change how the load is distributed in the bearing

ABB knows the most common bearing diffi culties and how

Cylindrical roller bearings Th ese roller bearings are used in applications where they must hold heavy radial loads In the roller bearing the roller is a cylinder so the contact between the inner and outer race is not a point but a line Th is spreads the load out over a larger area allowing the bearing to handle much greater radial loads

QIBR Cylindrical roller bearings (CRB)

These bearings can be used as locating bearings to locate the shaft axially in both directions Full complement cylindrical roller bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads However they cannot operate at the same high speeds as caged design cylindrical roller bearings

TYPES OF BEARINGS AND THEIR APPLICATIONS [BEARINGS]
