What is a deep groove ball bearing?
A deep groove ball bearing consists of an inner ring, an outer ring, balls and a cage running in deep circular-arc raceways. It carries radial loads plus moderate axial loads in both directions, with low friction and low cost — the most widely used rolling bearing. This tool includes ISO 15 / JIS B 1512 series 68, 69, 60, 62, 63 and common miniatures.
Choosing a size
The shaft sets the bore code; space and load set the series: 68/69 thin sections for tight spaces, 62 as the balanced default, 63 for the highest load. Ball size and count vary by maker; this tool estimates Dw ≈ 0.29 (D − d) with ~60 % ball fill on the pitch circle — for visuals and clearance checks only.

FAQ
What size is a 608 bearing?
608 is 8 mm bore × 22 mm outside × 7 mm wide — the bearing in skateboards, fidget spinners and many 3D-printer idlers. 608ZZ (metal shields) and 608-2RS (rubber seals) have the same dimensions.
How do I read a bearing number?
Take 6204: “6” = deep groove ball bearing; “2” = dimension series (8 extra-thin, 9 thin, 0 extra-light, 2 light, 3 medium); “04” = bore code — from 04 up multiply by 5 (04 → 20 mm); 00 = 10, 01 = 12, 02 = 15, 03 = 17 mm. In three-digit numbers like 608 the last digit is the bore.
What hole size should I print for a press-fit bearing?
For FDM, make the housing 0.1–0.2 mm larger than D (e.g. 22.15 mm for a 608); for SLA about +0.05 mm. Add another 0.1 mm for a slip fit. Print a test ring first — every printer differs.
ZZ vs 2RS?
ZZ = non-contact metal shields, low drag, good for high speed. 2RS = contact rubber seals, better against water and dust but slightly more drag. Outer dimensions are identical.
Which software opens the ball bearing STEP file?
STEP (AP214) opens in Fusion 360, SolidWorks, FreeCAD, Onshape and Rhino. STL / 3MF import directly into Bambu Studio, PrusaSlicer or Cura.

About STEP / STL / 3MF / DXF
- STEP (.step / .stp, AP214) keeps exact dimensions and surfaces for editing in Fusion 360, SolidWorks or FreeCAD.
- STL and 3MF are triangle meshes that import directly into Bambu Studio, PrusaSlicer or Cura.
- DXF is the top-view 2D outline, ready for laser cutting, waterjet or CNC routing.
- All models are in millimetres at true scale.
