Fields of application and Assembly examples of MSA
MSR series locknuts are precision nuts whose system-specific benefits can be used to advantage in every mechanical engineering sector. Where high-speed spindles or spindles subject to high levels of strain are used, their axial rigidity and high levels of dynamic safety ensure optimum results for the entire bearing system. Repeated precision adjustments can be carried out using the locknut on the same spindle. The locknut can simply and precisely assume the function of shaft collar or contact surface. Even where a union is expected to comply to only the most stringent demands, these locknuts can be ideally applied.
Following practical examples will give an overview of different applications:
Fig. 1: In tapered roller bearings, minimal axial run-out and a high level of axial rigidity and dynamic safety form a major contribution to perfect bearing operation: Radial stress applied to the tapered roller bearing generates axial force components (axial rigidity). Due to a lack of axial pretension (no axial friction), the intrinsic safety of the locknut is extremely important.
Fig. 2: By assembling using a locknut, the bearing of the ball roller spindle is lent a high degree of axial rigidity. Under highly dynamic operating conditions, the dynamic safety of the locknut represents a particular advantage.
