Product Description Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings. Sealed Bearing — Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat. Shaft Liners — Shaft liners allow you to use the bearing on unhardened and unground shafts.
