Simple mounting
Misalignments are compensated by the matched design of the housing and the radial insert bearing and the plus tolerance of the bore. Reworking of the shaft is no longer required. In addition, two self-retaining set screws that are offset by 120° securely locate the inner ring on the shaft. A suitable Allen key is supplied with every ball bearing unit. This reduces the mounting outlay to a minimum.
Quiet running and low friction
The Black Series Ball Bearing Units also make a convincing case during operation due to their proven FAG quality standard. The optimized internal geometry, honed raceways and high ball quality ensure quiet running and the low frictional torque of the radial insert ball bearings. This reduces the energy requirements of applications. The energy efficiency is further improved with the extremely low-friction plastic cage.
High reliability and long bearing operating life
Minimum friction also involves minimum heat generation and therefore a maximum grease operating life. The ball bearing units are supplied prelubricated and can be easily relubricated via a lubrication nipple if required. The seal that is firmly staked in the outer ring retains the grease in the bearing and thus allows easier relubrication. It has a vulcanized seal lip that effectively prevent dust and water entering the bearing. To protect the seal lip against damage an outer flinger shield is fitted on the inner ring. In addition, the radial insert ball bearings have an improved anti-corrosion protection. An antirotation pin locates the outer ring firmly in the housing. The robust Black Series Ball Bearing Units are most suitable for challenging operating conditions. The relevant application requires less maintenance. This saves the operator time and money.
Product range
The FAG Black Series Ball Bearing Units are supplied with both metric and inch bore diameters. Schaeffler Group Industrial is initially offering one pillow block housing unit as well as a two bolt and a four bolt flange unit. These will be followed by further housing types and a range of diameters that will be increased successively.
