Do I need to replace the original bearings?

If the bearings in your machine are in good condition, they can be reused by removing them carefully with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removing them can cause damage. To avoid this risk, we recommend replacing old bearings with our greased and sealed bearings, which are designed for lifelong use. We suggest adding the bearings to your shopping cart before checkout to ensure a successful upgrade.
