The most widely used rolling bearing type, built for radial loads plus moderate axial loads in both directions, low friction, and high-speed running. Available across the 6000, 6200, 6300, 6800/6900, and 16000 series with bore sizes from 3 mm to 500 mm, in open, ZZ, RS/2RS, and RZ/2RZ configurations.
Full dimensional tables, load ratings, and speed limits for every bore size, so you can select and cross-check against your drawing.
ISO-standard numbering that cross-references directly to SKF, NSK, NTN, FAG, and Koyo equivalents, with stable lead times.
Quickly match bore, OD, and width to the part you're replacing, and choose the right seal type for the environment.

A single row deep groove ball bearing consists of an inner ring, an outer ring, a single row of balls, and a cage, with raceway grooves deep enough that the ball-to-groove contact curvature lets the bearing carry radial load and moderate axial load in both directions at once — something many other bearing types need a second row or a separate thrust bearing to achieve.
Low internal friction supports high rotational speeds with minimal heat generation, and the design mounts simply. This mix of load versatility, speed capability, and low cost of ownership is why this type is the default choice across general industrial machinery.
Minimal rolling resistance allows sustained high-RPM operation with lower heat build-up.
Handles radial load plus axial load from either direction in a single bearing.
From extra-thin-section 16000 series to heavy-duty 6300 series, bore spans 3–500 mm.
Open, Z/ZZ shields, or RZ/2RZ and RS/2RS seals to match speed and contamination needs.
Standard ISO envelope dimensions mean easier installation, sourcing, and replacement.
Every batch is dimensionally inspected, with material and production records on request.
Each series trades off envelope size, load capacity, and speed differently. Use the comparison table below to narrow down, then open the series page for full dimensional tables.
The general-purpose baseline series for applications with no unusual space or load constraint.
View 6000 Series
Larger balls and higher load rating than 6000 series at a similar bore.
View 6200 Series
Wider width and larger balls for the highest load capacity in the standard-width family.
View 6300 Series
Slimmer ring cross-section for space-constrained housings.
View 6800/6900 Series
The slimmest ring section relative to bore, for the tightest axial housing depth.
View 16000 Series
Non-catalog bore, OD, or width, special materials, coatings, or branding.

|---|---|---|---|---|---|---|
| 6000 | 10–500mm | 26–620mm | Standard | Baseline | High | General-purpose, no unusual constraint |
| 6200 | 10–200mm | 30–360mm | Standard+ | Above baseline | Medium–High | Need more load than 6000 at similar bore |
| 6300 | 10–200mm | 35–420mm | Wide | High | Medium | Heavier radial loads, width not constrained |
| 6800 / 6900 | 5–110mm | 13–170mm | Thin | Low–Moderate | High | Housing depth limited, small-to-medium bore |
| 16000 | 12–100mm | 28–156mm | Extra-thin | Moderate | Medium–High | Large bore needed, axial space severely limited |
No shield or seal. Lowest friction and highest speed; best where lubrication and cleanliness are externally controlled.
Metal shield on one or both sides. Keeps grease in and coarse contaminants out with minimal added friction.
Non-contact rubber seal on one or both sides. Better sealing than a shield with only a small speed penalty.
Contact rubber seal on one or both sides. Best protection against dust and moisture for lower-speed environments.
