› ROBUST series also can be used for ultra high speed applications of over 3 million d mn ROBUST Series: BNR BER High-Speed Angular Contact Thrust Ball Bearings High rigidity thrust bearings for lathe applications › Contact angles: 30˚ (BAR) 40˚ (BTR) › Ball material: steel (S type) ceramic (H type) ROBUST Series: BAR BTR Ultra

The angular information is computed from both vectorial components of the flux density (i e BX and BY) Then an output signal proportional to the decoded angular position is produced Our sensors do not rely on expensive bearings what affords Piher to offer the best price in the market

With angular contact ball bearings running at high speeds the increase of stiffness will be greater due to the improved dynamic behaviour of the balls i e the smaller change in contact angles The smaller deformation in the contact zone of the ceramic rolling element and the steel ring also means that the contact area will be smaller

Double Row Angular Contact Ball Bearings

The axial load carrying capacity is dependent on the contact angle i e the larger the angle ( = 30) the higher the axial load to which the bearing can be subjected Without filling slot Bearings of series 32 -BD and 33 -BD are self-retaining and do not have filling slots in the end faces of the bearing rings The contact angle is = 30

The angular contact ball bearing is able to carry combined radial and axial loads or pure axial load In this type of bearings the loads are transmitted from one raceway to another at a certain contact angle The ISO has given the nomenclature of various dimensions of single and double row angular contact ball bearing as per IS: 2399-1988/

Angular contact ball bearings

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane along which the combined load is transmitted from one raceway to another and a line perpendicular
