The Z809 is a small-format bearing with an 8mm bore (d), 22mm outer diameter (D) and 7mm width (B). Sizes in this range typically sit in compact drive or support positions where space is tight and the assembly needs to stay lean. If you're matching a bearing to an existing design, these three dimensions are a good first cross-check against your drawing. A dimensional match, though, doesn't confirm suitability on its own — whether it works in your equipment also depends on speed, load and operating environment, not just the outline.
Two bearings can share the same 8×22×7mm footprint yet behave differently from one machine to the next, and the reason usually lies in the running conditions rather than the size. Before evaluating the Z809, it helps to have three things in view: the expected running speed, the actual load pattern (radial, axial, or a mix), and the operating environment (dust, moisture, temperature swings). These directly shape the selection call. Suitability still needs to be confirmed against your real duty; if you can share these details, we can help assess whether the Z809 fits or point toward a more appropriate specification.
Small bearings in the 8×22×7mm range are often found as candidates in small motors, office and household equipment, precision drive mechanisms, and space-limited rotary supports. These are directions commonly seen for this size class — not a claim that the Z809 fits every case above. Whether it's the right choice still depends on your equipment structure, load and speed. If you already have a defined application in mind, describing it to us directly usually gets you to an answer faster than working from a generic list.
ISK Bearings is certified to IATF 16949, RoHS, REACH and SGS, with tolerance control down to 0–0.003mm. Beyond supplying the standard size, if your application calls for secondary machining, surface treatment or overmoulding on top of the bearing, we can bring those steps together under a single coordination flow — which cuts down the back-and-forth of managing several suppliers yourself. If you already have a model number, drawing or sample, feel free to send it along and we'll help you assess the next step.
Some non-standard or currently out-of-stock bearings may not be immediately available. If you have specific requirements, feel free to contact us — we will do our best to confirm lead times and provide alternative solutions.
