DIN 616-2000 pdf free download.Rolling bearings General plan for boundary dimensions.
DIN 616 specifies a general plan for the boundary dimensions of radial and thrust rolling bearings. Inaddition, it describes the system of dimension plans and series making up the general plan.
This standard does not provide information regarding the internal design of rolling bearings (e.g.bearing rings,rolling elements, cages, seals), nor does it specify which dimension series and plans are suitable for particularbearing types.These are given in the relevant product standards.
The objective of this standard is to restrict the number of bearing sizes enough to ensure economic productionand yet to provide a sufficient number of sizes to satisfy present and future needs of bearing users.

3System of dimension series and plans3.1General
The general plan specifies the major boundary dimensions of rolling bearings, i.e. bore diameter,outsidediameter, width or height, and the chamfer dimension, r, which is equal to the minimum chamfer dimension, r5min(cf.ISO 104).
For ease of reference, table 1 lists the bore diameters, d,ranging from 0,6 mm to 2000 mm, and the associatedcode numbers.As a rule, the nominal bore diameter can be determined by multiplying the code number with afactor of 5.For bore diameters of less than 20 mm and of 500 mm or more, the code numbers are identical tothe bore diameters.For bore diameters of 10 mm, 12 mm, 15 mm and 17 mm, code numbers are specified fromwhich the bore diameter cannot be derived as explained above.
Boundary dimensions not given in the general plan may be obtained by calculation.
Since different outside diameters are to be assigned to one particular bore diameter, diameter series have beenset up, where D values are given which have been derived using certain calculation factors. For the differentwidths and heights to be assigned to one particular sectional width orheight of each diameterseries, widthserieshave been set up for radial bearings and height series for thrust bearings, where B and T’values are given whichhave also been derived using certain factors.
The values for the minimum chamfer dimension, r, have been derived from the sectional width or height of thebearing or from the specified B and T values.
The values for the other boundary dimensions have been obtained by calculation orspecified on acase-by-casebasis.
The combination of a diameter series with a width series forms a dimension series for radial bearings and thecombination of a diameter series with a height series forms a dimension series for thrust bearings. A dimensionplan is made up of the boundary dimensions assigned to a dimension series.
Diameter, width and height series are identified by codes.
For diameter series, the following codes are used:
– 7,8,9,0，1,2,3,4 and 5 for radiat and thrust bearings;
– 7C,8C,9C,0C,1C,2C,3C, 4C, and 5C for radial needle roller and cage assemblies;
– 7D,8D,9D,OD,1D,2D,3D,4D, and 5D for open end and closed end drawn cup needle roller bearings:-7E,8E，9E,OE，1E,2E,3E,4E, and 5E for thrust collars (reinforced type only).DIN 616 pdf download.
