Free deep groove ball bearing blocks for AutoCAD (DWG): ISO 15 series 618 to 64

About the dimensions

The dimensions are the boundary dimensions of ISO 15: bore d, outside diameter D, width B and the smallest chamfer rs min, for the dimension series 18, 19, 10, 02, 03 and 04 and bores up to 100 mm, 190 bearings in total. Tolerances, internal clearance, load ratings, shoulder diameters and sealed or shielded versions are not part of the blocks.

The bearings are our own simplified drawings, not copies of the standard, and the library is not certified. The rings and the ball show the size and the space the bearing needs, not the internal design of a particular maker. Take tolerances, load ratings and fits from the standard and from the catalogue of your bearing supplier.

Frequently asked questions

Which bearings are included?

The deep groove ball bearings of the series 618, 619, 60, 62, 63 and 64 with all bores from 0.6 to 100 mm listed in ISO 15: 36 of the series 618, 35 of 619, 34 of 60, 31 of 62, 31 of 63 and 23 of 64. Larger bores, the series 7, 8 and 9, angular contact, roller and thrust bearings are not included.

Are the bearings drawn at real size?

Yes. Bore, outside diameter and width are in millimetres at scale 1:1, so a 6205 measures 25 mm in the bore, 52 mm outside and 15 mm wide. The block is usable in an assembly drawing, for a shaft and housing layout or for a clearance check.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.

Can I use the blocks for the shaft and housing design?

The blocks give the bearing envelope: bore, outside diameter, width and chamfer. Use them to place the bearing in the assembly, and take the shoulder diameters, fits and tolerances from the standard or from your bearing supplier.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
