Frequently asked questions — Mounting and Locking Accessories

• How do I choose locking accessories suited to my bearings?

  The choice of mounting and locking accessories must align with the mechanical requirements of your rotating assembly. You must verify dimensional compatibility with the shaft and housing in accordance with the boundary dimensions defined by the ISO 15 standard for radial bearings. It is also necessary to take into account load conditions, whether static according to the ISO 76 standard or dynamic in accordance with the ISO 281 standard, to ensure the components are properly held in position.
• Why comply with the ISO 15 and ISO 492 standards during mounting?

  Compliance with the ISO 15 and ISO 492 standards is fundamental to ensuring optimal rotation of your system. The ISO 15 standard sets the boundary dimensions essential to compatibility between the shaft, housing and mounting accessories. In parallel, the ISO 492 standard defines the operating tolerances required to maintain the necessary mechanical precision, thereby preventing failures linked to incorrect positioning of elements within the assembly.
• Which technical parameters should be considered when sizing accessories?

  To correctly size your accessories, you must accurately assess the load capacity of the assembly. The ISO 76 standard is used to determine the static load, whilst the ISO 281 standard is used to calculate the dynamic load and estimate the basic rating life. This data, combined with dimensional tolerances, ensures the effective retention of your plummer blocks, thrust bearings, rollers or bearings, whether self-aligning or cylindrical roller types.
• Are the accessories compatible with all types of bearings?

  These accessories are specifically designed to be inseparable from systems including plummer blocks, thrust bearings, rollers, as well as self-aligning or cylindrical roller bearings. For rigid or specific mountings, including deep groove ball bearings governed by the DIN 625 standard, it is recommended to use components from brands such as TIMKEN, SKF, FAG or INA. These manufacturers guarantee the precision required to meet the technical demands of your assembly.
