Miniature Bearings Design Materials
This type of bearing can handle thrust loads in one direction only Materials Miniature and instrument bearings are normally made of either stainless steel or chrome alloy steel National Precision Bearing offers stainless steel for applications that require corrosion resistance and 52100 chrome steel for maximum fatigue life
Radial and Axial Load Rating Information for SMB Bearings
The axial load capacity of a radial ball bearing can be increased by specifying loose radial play Axial load rating Heavy duty bearing types such as 6200 or 6300 series may take axial loads of up to 50 percent of the static radial load rating Thin-section deep groove ball bearings can only support axial loads of between 10 and 30 percent of

AXIAL RADIAL MOVEMENT CONSIDERATIONS
AXIAL RADIAL MOVEMENT CONSIDERATIONS Axial The groove width A or B must be widened by twice the axial play if play occurs in the area of the rings Damage to the rings and the surrounding components may occur if this is not adhered to It is recommended to use the full groove width tolerances especially in cases involving thermal expansion
Fitting and Mounting of Radial Ball Bearings
The size and type of bearing specified – Thin type and miniature bearings are very sensitive to interference fits due to loss of radial play Bearings with heavier cross sections generally require tighter fits Material and manufacturing tolerances of mating components – Fit tolerances are based on cast iron or steel housings and shafts
Radial Ball Bearings
Radial ball bearings are the most widely used type of rolling element bearing in the world today due to their versatility and overall performance Below is a cross sectional view of a typical radial ball bearing These bearings are produced with high quality materials and exacting tolerances
design characteristics of radial ball bearings
Axial location – improved axial location is obtained with Thrust type bearings Two important internal parameters which must be considered and specified when a bearing is selected are: Radial play internal clearance – the total diametrical movement from contact at one side between rings and balls to similar contact at the other side
Radial Deep Groove Bearings by Boca Bearings :: Ceramic
Radial deep groove bearings are made with very high levels of precision and used in applications where rotational performance and low torque is necessary but load is a secondary issue Miniature Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings but are also less tolerant of misalignment

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 play
Radial play has nothing to do with precision grade or tolerance A loose bearing does not necessarily mean a low precision bearing You can have a P4 (Abec7) grade bearing with a loose radial play just as you can have a P0 (Abec1) bearing with a tight radial play so too much play suggests a tighter radial play or an axial preload is needed

Miniature Instrument Bearings Radial Contact Bearings (Deep Groove Bearings) QIBR Super Precision (MPB) Radial Contact Bearings are available in inch and metric sizes and are all made to ABEC 7P tolerances Standard Radial Play is 0002/ 0008 but other ranges are also available
RELATIONSHIP BETWEEN RADIAL CLEARANCE AXIAL
In bearings of the same type axial clearance depends on the radial clearance Contact Angle The contact angle is formed between the connecting line of the contact points ball/raceways and a plane perpendicular to the axis It is formed when the axial clearance is removed by the opposite axial movement of the bearing rings The contact angle
