Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.

When installing or removing SKF bearings, improper techniques can lead to scratches on the raceway and rolling surfaces. These scratches often appear as linear marks caused by misalignment of the inner and outer rings or excessive impact during the installation process.
Such damage is commonly the result of incorrect handling, such as applying too much force or not using proper tools. It's important to ensure that the bearing is centered correctly during installation to prevent uneven pressure and subsequent surface damage.
To avoid scratches on SKF bearings, it’s essential to use appropriate tools and follow the correct procedures. Using a hydraulic press instead of a hammer can significantly reduce the risk of impact damage. Additionally, always check that the bearing is aligned properly before applying any force.
Proper maintenance and careful handling are key to extending the life of SKF bearings and ensuring their optimal performance. Always refer to the manufacturer’s guidelines for specific installation and removal instructions.
