Use a thread insert kit to replace a stripped thread or add a threaded insert into sheet metal, fiberglass or other brittle material. Choose from kits with standard inserts or helical inserts (also known as helicoil inserts). Thread repair kits include everything you need to repair or install threaded inserts, including a hand drill and installation tool to speed maintenance and reduce downtime.

When installing or removing SKF bearings, improper techniques can lead to scratches on the raceway and rolling surfaces of the bearing. These scratches often appear as linear marks and are usually caused by misalignment between the inner and outer rings, or by excessive impact during installation or disassembly.
Such damage not only affects the performance of the bearing but can also reduce its service life. To prevent this, it's crucial to use proper tools and methods during the installation process. Avoid using hammers or other forceful tools that can cause unnecessary stress on the bearing components. Instead, use a hydraulic press or a bearing puller to ensure even pressure and alignment.
Proper centering is another important factor in preventing scratches. Make sure the bearing is aligned correctly with the shaft or housing before applying any force. This helps distribute the load evenly across the bearing, reducing the risk of damage.
In addition, always check the condition of the bearing before and after installation. If you notice any signs of scratching or damage, replace the bearing immediately to avoid further complications.
