New BEARINX®-online Easy module for designing rope sheave bearing supports

Schaeffler expands its rolling bearing calculation service

In order to fulfill customers' ever-increasing demands, Schaeffler is continuously updating and expanding its long-established BEARINX® rolling bearing calculation program. In addition to products with optimized friction and performance characteristics, modern calculation and simulation tools play a key role in increasing the efficiency of rolling bearings.

With "BEARINX®-online Easy RopeSheave", every Schaeffler customer can now calculate the static load safety factor and rating life of both single and multiple rope sheave bearings. It is available exclusively online and can be used free of charge. Initial registration takes very little time and the customer can begin calculation work immediately.

New: The "Easy series" for online customers

Customers can quickly and safely browse through and compare a range of bearing support variants at http:\\ The self-explanatory menu navigation enables users to enter data quickly and easily for modeling, bearing selection, and operating data.

The data for radial roller bearings, radial deep groove ball bearings, and radial tapered roller bearings from the INA and FAG brands are stored in the database and can be accessed and integrated into the calculation process at any time.

Influencing factors that are typical for the application, such as consideration of the rope sheave material, the integration of a bush between the bearing and plastic rope sheave, precise data on the bearing's internal geometry, and the influence of the system temperature on the bearing clearance are also relevant for the calculation.

Extra module for rope sheave bearing supports

BEARINX® enables users to calculate, display, and document the specific bearing loads in detail while taking operating and environmental conditions into consideration - even for complex machine systems. The contact pressure on every single rolling element is considered in the calculation.

There is a dedicated module for rope sheave bearing supports that allows even several adjacent rope sheaves to be calculated precisely. BEARINX® takes into account factors such as the non-linear elastic deflection behavior of the rolling elements, contact angle shifts in radial ball bearings caused by the load, the elasticity of the axis, and the real contact pressure depending on the skewing and profiling of the rolling elements.

The saved files can be exchanged with Schaeffler's Engineering Service, who can then carry out a final inspection. The objective is to offer the customer optimized and efficient support in his or her own product development at all times and, in doing so, shorten development times wherever possible.

The program's outstanding performance, combined with the specialist knowledge of Schaeffler's application engineers and the customers' practical experience, generates innovative and technically sophisticated solutions.
