Bearings are the parts that give the earliest warnings and get ignored the longest. A little bit of noise, a little bit of heat, a little bit of vibration — none of it seems urgent, so it waits. Then one day the shaft's ruined, and the "little bearing job" is a big teardown.
This is the genuine Nilfisk Advance OEM BEARING 6204, part number ZD45425, brand new in the box. Replace early on symptoms; don't wait for failure. The part is cheap, the labor's manageable if you catch it before other damage.
