Product Portfolio

  • Standard range - An extensive bearings range, with precise solutions

  • SNR proposes an extensive, competitive standard bearing range including all main ball and roller bearing families, as well as the PREMIER bearings, of optimised design, and highly technical bearings tailored to your trade (TOPLINE, MachLine).

    Thanks to its extensiveness, our range covers the most diversified industrial applications and allows every need to be met. Besides, the latest technological breakthroughs and research works conducted by SNR allow us to propose top quality bearings, notably providing higher service life and load capacity.

    SNR also proposes bearing components and accessories, available separately, enabling you to carry out your own assemblies. Firstly ensure that your components, intended to accommodate the bearing elements, share the same characteristics (quality, bearing raceway precision, hardness…) as those of the bearing delivered complete.

    • ULTAGE, the concept of Ultimate Performance for your satisfaction

      • ULTAGE : Higher machine efficiency

      • ULTAGE : Lower maintenance cost

      • ULTAGE : Reduced environmental impact

    • Single-row radial contact ball bearings
       

    • The SNR single-row radial contact ball bearing range is suitable for the most diversified applications. Designed essentially to sustain moderate radial loads, these bearings, which are the most commonly used, also sustain moderate axial loads in all directions. They are particularly suitable for applications with high rotating speeds and when energy loss limitation is sought.

    • Double-row ball bearings
       

    • SNR double-row ball bearings have become the natural substitute for single-row ball bearings for higher radial load applications, or for axial loads in both directions. Suitable for mean rotating speeds, these bearings only admit very slight misalignment between shaft and housing, to the order of 0.06°.

    • Tapered roller bearings

       

    • Tapered roller bearings are angular contact bearings comprised of separate components (cones and cups), facilitating installation. By design they are suitable for combined loading. They can sustain very high loads (axial load in one direction) and tolerate slight misalignment.
       

    • Cylindrical roller bearings
       

    •  The cylindrical roller Series includes several variants to permit accurate bearing selection and, therefore, improve machine efficiency. SNR's quality and innovation are at the heart of these bearings whose optimised contact between roller and raceway reduces internal loads.

    • ULTAGE double-row spherical roller bearings

    • From 25 mm bore up to 2180 mm external diameter to fit all needs

      NTN-SNR offers a wide range of spherical roller bearings on the market. They are available in different cage versions.

    • Ball thrust bearings

       

    • SNR has developed a complete range of high quality ball thrust bearings. Thrust bearings are designed to maintain the shaft in one single direction. They admit low rotating speeds and sustain high axial loads. You are strongly advised against submitting them to radial loading. Ball thrust bearings are comprised of separate items facilitating installation and maintenance. Grease and oil lubrication is feasible.

    • Bearing components and accessories
       

    • SNR balls are essentially intended to equip bearings. However, they are suitable for many other applications.

      Steel balls are used in most cases. They are available in a large diversity of diameters (metric or imperial dimensions) and hardness values. They are classified according to their tolerance (i.e. their dimension and shape precision).
       

    • MachLine® - High Precision
       

    • Precision, stiffness, high speeds: SNR High Precision bearings meet the most stringent needs.

      They also permit machining timesavings as well as maintenance cost savings, and their good load capacity and low heating feature contribute to longer service life.

  • Special bearings - Innovate with SNR special bearings

  • Collaboration with the engineers and technicians of our OEM clients’ Design & Engineering Offices must be effective at all levels. Therefore SNR devotes significant human resources and equipment through its Special Products Division, which groups all actors involved in the special industrial product development and manufacturing processes.

    Each development and each specific project is a good occasion for our clients and in-house experts to innovate by making the mechanical rotation function more efficient and economical.

    Jointly with you, we are pushing the limits and constraints of the design and efficiency of your machines by combining suitable steels, new shapes, high performance contacts and tailored seals and lubrication modes.
