Product description of FAG Bearing HC71900-E-T-P4S-UL

FAG Bearing HC71900-E-T-P4S-UL,Spindle bearings are single-row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed designs.

FAG Bearing HC71900-E-T-P4S-UL, Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and suitability for high speeds. They have proven ideal for spindle bearing arrangements in machine tools.

With its “M series”, Schaeffler presents a new, technically and economically sophisticated concept for increasing the productivity of machine tools. Three X-life High-Speed spindle bearing versions offer great potential for increasing the load carrying capacity of motor spindles even further with regard to maximum speed, high machining forces, and high temperatures.

M version – Cost-effective and robust
HCM version – For outstanding productivity
VCM version – New degrees of freedom in design
X-life

Bearings of X-life quality have an improved raceway geometry and optimized surfaces. This provides a significant increase in the fatigue limit load of the bearings. When calculating the expanded adjusted service life, values up to 50% higher are achieved. In certain applications, this means that a smaller bearing arrangement can be designed.

Various sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables.

FAG Bearing HC71900-E-T-P4S-UL, FAG super precision bearings for main spindles stand for very high precision and absolute operational security. Innovative FAG spindle bearing solutions are continually raising standards in relation to speeds, accuracy and rating life. For the main spindle system and the overall machine tool system to be successful, however, bearing components alone are no longer sufficient as a guarantee.Significant increases in performance and the creation of unique selling propositions for the customer are now achieved when the bearing manufacturer offers advice and carries out development work on the basis of wide-ranging system knowledge as well as being able to provide support through a range of service functions.It is through close partnership with the manufacturers of spindles and machine tools and through shared knowledge, founded on experience, of the requirements of end users and their customers that the potential exists for achieving a leading role in the market.
