Tornado Tempest Bearing 687 ZZ K64222140

This is the 687 ZZ bearing used in the Tornado Tempest filter and blower assembly. Tacony publishes the bearing designation in the part description, which is why this one is titled by its specification rather than by its position — 687 ZZ is a miniature deep-groove ball bearing with metal shields on both sides.

What the Bearing 687 ZZ Does

The ZZ suffix is the important half of that designation. It means the bearing is shielded on both faces, which on a machine full of fine carpet dust is not a detail: an open bearing in this environment fills with lint and fails quickly. The shields keep the grease in and the dust out for the working life of the part.

Where It Sits on the Machine

It is fitted in the filter and blower assembly on the Tempest filter and blower diagram, supporting the shaker mechanism.

When to Replace It

Replace the bearing when it feels rough or notchy turned by hand, when it is noisy in use, or when there is any play in the race. Bearings usually give warning well before they seize, and replacing one that has started to feel rough avoids the collateral damage a seizure causes to the shaft and linkage around it.

Fitting Notes

Press the new bearing in squarely on its outer race rather than driving on the inner one, which damages the races. Turn it by hand after fitting to confirm it runs freely, and check the shaft it carries for scoring while everything is apart.

What does 687 ZZ mean?

It is the bearing’s standard designation. 687 gives the dimensions of a miniature deep-groove ball bearing, and ZZ means it is shielded on both sides. The shields matter here because the bearing works in a dusty environment, and an unshielded equivalent will fill with lint and fail early.
