You've probably dealt with gearbox failures where misaligned loads cause vibration and premature wear, leading to downtime you can't afford — that's the core headache this bearing solves by handling both radial and axial forces with its deep groove raceway design, which is non-separable and built for stability under mixed loading conditions.
So what it does is use a single row of balls running in a continuous groove, and the steel cage keeps them evenly spaced even at high RPMs, which is better than polyamide cages for heat resistnce in motor applications, and most buyers go with the P6 or P5 precision grade unless you need the tighter tolerance of P4 for high-speed spindles.
Basically, the bore ranges from 6mm to 90mm, outer diameter form 17mm to 140mm, depending on your gearbox shaft size, and load ratings sit between 0.31 and 44.63KN while static goes 0.72 to 39.16KN — we usually have stock on the 6000 through 6010 series, but the larger bores above 60mm or so might need a 20-day lead time (check that when you're ready to order).
It runs on grease up to 8500rpm or oil up to 12000rpm at the lower end of the speed range, but at the smaller bore sizes, max speed can exceed 38000rpm with oil lubrication, and we include a COA with every batch showing the noise level and dimensional tolerances — though it's not suitable to heavy axial-only loads where a thrust bearing would be a better fit.
Chrome steel construction with ground raceways gives you smoother surfaces than standerd commercial-grade bearings, reducing friction by about 15-20% in our tests, and the steel cage handles temperatures up to 150°C without deformation, which matters when your motors run hot, so these are pretty much the go-to for industrial machinery buyers who need consistent performance at around 3000-5000rpm continuous duty.
The 6000 series comes in P0, P6, P5, P4, and P2 precision ratings. For gearbox applications, P5 or P4 is typically recommended for better accuracy and reduced vibration.
Yes, we offer OEM service for custom sizes within the standard range—bore from 6-90mm and outer diameter from 17-140mm. Just share your specs, and we can adjust accordingly.
Lead time depends on the quantity and precision grade, but standard orders usually ship within 15-30 days. Custom or higher-grade bearings (like P2) may take a bit longer.
Yes, we can provide ISO certification and material test reports for chrome steel upon request. Just let us know what documentation you need with your order.
The MOQ typically starts at 100 pieces per size, but it can vary based on the specific model and precision rating. Contact us for exact numbers on bulk orders.
Bearing the brunt of a tight project deadline, I was immensely relieved by the exceptional logistics performance surrounding this order.
