Heavy Duty Ball Screws Diameter 50 - 160 mm

Product catalog summary

Introduction
Steinmeyer's UltraThrust ball screws are engineered for high load transmission, differing from conventional ball screws in design and material treatment to meet specific application requirements. These screws are typically assembled with no or low preload.

Specifications
The document details heavy-duty ball screws with nominal diameters ranging from 50 to 160 mm. Key specifications include:

Single nut execution grades P0 - P5.
Series 3414: Nut with flange, single start, external return.
Series 1414: Nut with flange, single start, internal return.
Series 1213: Cylindrical nut, single start, internal return.
Series 3424: Nut with flange, dual start, external return.

Technical Data
The document provides detailed technical data for various models, including:

Nominal diameter (dN) and lead (P) in mm.
Number of circuits (i) and ball diameter (dw) in mm.
Dynamic load rating (ca) and static load rating (c0a) in kN.
Maximum axial load (Fmax) in kN.
Dimensions such as nut diameter (m), nut length (l), and mounting specifications.

Recommendations
It is emphasized that the high static capacities are due to the desired dynamic load capacities and should not be mistaken for operating loads. Maximum permissible loads are specified in the document.

Conclusion
Steinmeyer's heavy-duty ball screws are designed for applications requiring high load transmission, with specific attention to material selection and design optimization for large ball sizes.

H e av y D u t y B a l l S c r e w s ( U lt r a Th r u s t ) UltraThrust ball screws from Steinmeyer are not merely larger sizes of conventional ball screws. They have been specifically designed for the purpose of transmitting very high loads. The ball returns for example have been optimized for large ball sizes and for the specific use of such large screws. Also the robust nut body and the flange differ from conventional designs. Material selection and heat treatment take into account the special application requirements. Please keep in mind that the extremely high static capacities of such...
