Bearing Selection

According to the theory of elastic contact of bearings the height of the inner and outer ring flanges is matched to meet the requirements of heavy motor overload For low and medium loads select ball bearing and for heavy load select roller bearings Aside from the axial load and radial load the product must overcome the tilting torque

RKB Bearing Industries The Swiss World

RKB produces this type of bearing called TORB which was introduced in the early 1990s RKB toroidal bearings are used in presence of high radial load and they can withstand also important misalignments They are usually mounted as non-locating bearings since they can withstand a very large axial thermal expansion of the shaft

Miniature Bearings • Bearings • The Industrial Resource

Miniature ball bearings are machined components constructed from an outer race inner race balls retainers shields and snap rings Because rolling balls have a lower coefficient of friction than do two flat surfaces that rotate on each other these bearings reduce rotational friction while still supporting radial and axial loads Due to limited contact area between the balls and races

Radial Play

Radial play should not be confused with tolerance grade and is entirely separate Axial Clearance measured along the bearingaxis is known as axial play Axial play is approximately 10 times the radial play value Radial play (or internal radial clearance) is an important consideration when choosing a

Miniature Bearings Radial Axial Play

Since radial play and axial play are both consequences of the same degree of looseness between the components they bear a mutual dependence Yet their values are usually quite different in magnitude Radial play can often vary between 0002 and 0020 while axial play may range from 001 to 010

Bearing design considerations for hand tools

This is referred to as radial play in most bearing catalogs In power hand tool applications this internal clearance must be removed for a pair of bearings to operate properly The application of an axial load across the pair of bearings – for the purpose of removing free internal clearances – is called preload

Selecting preload

Considerations for preload Depending on the bearing type preload may be either radial or axial Super-precision cylindrical roller bearings for example can only be preloaded radially because of their design while angular contact ball bearings or tapered roller bearings can only be preloaded axially

Bearing tolerances explained

Radial runout for radial ball bearings (other than angular contact bearings) is measured by mounting the bearing on an arbor that is determined to have a diameter that is straight to less than 0002 in/inch length taper The outer ring is held stationary while the inner ring (arbor) is rotated one full revolution

Radial Play

Radial play or internal clearance is the internal radial looseness in a bearing and is the measured value of the total radial movement of the outer ring with respect to the inner ring in a plane perpendicular to the bearing axis Ball bearings are assembled to radial play values depending upon a desired range The radial play is determined by the actual raceway diameters and ball diameter

An explanation of bearing internal clearance or radial

Internal clearance or radial play is the amount of looseness between the balls and raceways of a bearing For the actual clearances used in the radial play groups please see our RADIAL PLAY TABLES Radial play is the clearance measured perpendicular to the bearing axis or more specifically: average outer ring raceway diameter minus average inner ring raceway diameter minus (2 x ball diameter)
