Face-to-Face, DF Radial Play > F-Type Radial play (diametral clearance) is the distancethe inner ring can be moved radially from one ex- treme position to the other. Standard RBC Thin Section Ball Bearings are manufactured with enough radial play that some clearance remains after the bearing is properly installed.

BC manufactures many custom bearings designed to optimize bearing performance for specific applica-tions. Special features include changes in radial play, lubri- cants, materials, preloading and design. Contact your RBC Sales Engineer for your custom bearing needs. > Challenge us: There are many design options availableto solve difficult application problems. The radial play (diametral clearance) of a thin sectionball bearing will need to be predetermined if mounting fits other than those recommended are used. Special radial play may be required for a temperature differential across the...

n addition to the standard RBC Thin Section Ball Bearings, RBC will also manufacture specially designedbearings for specific applications. RBC Sales Engineers andCustomer Service Representatives are available for consultation. Continuous Rotating Machine Tool Table Using a 4-point contact RBC Thin Section Ball Bearing provides stiffness for accurate positioning as well as carrying multiple loads. RBC supplied this assembly as shown. Machine Tool Indexing Table Running at slow speeds with combined load carrying capabilities and minimal space determined the use of this 4-point RBC Thin...

Radar Antenna Drive An RBC Thin Section Ball Bearing designed with a gear integrated with the inner ring, achieved both a significant weight reduction and improved accuracy as well as sim- plicity of assembly. This bearing is used in a radar antenna drive which has limited space available for its support bearing. Coil springs were used as spacers between balls to lower bearing torque and further reduce weight. > .500 in.26.750 in.27.750 in. Aircraft Gun Turret Abearing was required which would take radial, axial, and moment loading, to support an aircraft gun turret. It was desirable to...
