UPC:
✔️ Dimensions 7mm ID 11mm OD 3mm width ZZ steel shields
Durable miniature sealed bearings come packaged individually to handle tight rotational loads in compact mechanical assemblies. Hobbyists and repair techs mount these directly onto micro servos, compact gearboxes, and precision turntables that demand zero play during spin cycles. The rubber reinforced flanges lock in fresh lubricant so you get quiet operation straight from the stash.
✅ Dual shield design traps premixed grease inside the rolling pathway✅ Hardened chromium steel tracks minimize heat buildup during extended run times
✅ Tightly controlled clearances prevent axial drift under sudden impact forces
✅ Metric footprint slots directly into standard bracket layouts for handy swap jobs
💡 Why prefer sealed units over open variants for sensitive machinery?
Factory loaded compounds give you handy uptime right away without messy shop prep routines.
- Interlocking metal faces block gritty dust from scoring polished inner rings
- Consistent drag coefficients lower power draw rates across varying RPM bands
- Heat treated alloy composition holds gauge accuracy after repeated thermal shifts
