The right bore size, load rating or series can be the difference between a bearing that lasts and one that fails early. Here's how to get it right the first time.
Not an engineer? You don't need to be. Tell us your bore size, load and application — we'll tell you exactly which series to order.
We manufacture six standard series, covering bore sizes from 5mm to 100mm. Each series is built for a different load and space requirement — find the one closest to your spec below, or send us your bore size and we'll confirm the match.
Our highest-volume series and the industry standard. Slim cross-section fits compact housings — the default choice for small motors, power tools, household appliances and general machinery.
Get a Quote →Wider cross-section than the 6000 series for greater radial load capacity at the same bore size. Widely used in electric motors, pumps and automotive components.
Get a Quote →Our heaviest standard series — larger balls and thicker rings handle higher radial and axial loads in gearboxes, conveyors and industrial drives.
Get a Quote →Thin-wall, extra-light design for applications where radial space is limited — printers, cameras, small drive shafts and precision instruments.
Get a Quote →Narrower and lighter than the 6800 series, built for compact, weight-sensitive assemblies such as robotics, drones and miniature motors.
Get a Quote →Thin-section series with a wider bore-to-width ratio than the 6000 series — used where a larger bore is needed but installation space stays tight.
