Tornado Tempest Square Bearing K50321900

The Tornado Tempest square bearing (part# K50321900) is the square-bodied bearing block in the battery housing and controls assembly of the TV400-W26-U cordless sweeper. The square body is not a detail — it is what stops the bearing rotating in its pocket, so the adjustment mechanism turns inside the bearing rather than taking the whole bearing round with it.

Bearings of this type fail quietly. They do not usually seize; they wear oval, and the mechanism they support develops play that shows up somewhere else entirely. On the Tempest that play appears as a brush height setting that will not hold, which sends people to the knob, the bushing and the lever before they get to the bearing.

Compatible Models for the Square Bearing

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

Symptoms that point to the square bearing

• Play in the adjustment mechanism that persists after the knob and bushing have been renewed.
• The bearing can be rocked in its pocket by hand.
• The bore is visibly oval rather than round.
• Rough, notchy or noisy movement through the adjustment range.
• The square body is chipped or has spun in its pocket, rounding the corners.

A bearing that has spun is the one to catch early — once the corners of the pocket round off, the housing itself starts to need attention rather than just the bearing.

Fitting notes

Remove the battery pack before starting. The bearing seats in the battery mount (part# K50321850) supporting the adjustment train. Check the pocket for rounding when the old bearing is out; a pocket that no longer holds the square body squarely will let a new bearing spin too. Fit it dry unless the original was lubricated, and confirm the adjustment turns smoothly with no rock before reassembling.

Frequently Asked Questions

What does the square bearing do on the Tornado Tempest?

It supports the brush height adjustment mechanism. Its square body locks it in its pocket so the mechanism turns inside the bearing rather than rotating the bearing itself.

How do I know if my square bearing needs replacing?

Play in the adjustment that survives renewing the knob and bushing, a bearing that rocks in its pocket, an oval bore, or rough and notchy movement. A square body with rounded corners means it has been spinning.

What models is the square bearing (part# K50321900) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone.
