Decoding the designation

6013 — NSK’s number for the ISO 6013 size, 65 x 100 x 18 mm, in the 60 extra-light dimension series.

P4 — ISO tolerance class 4, equivalent to ABEC 7: bore, outside diameter and running accuracy held far tighter than a standard bearing.

TC, G12 — NSK order-code positions carried on the carton, recorded here as part number variants.

What these specs mean in practice

A deep groove ball bearing carries radial load and moderate thrust in either direction from a single row of balls running in deep, closely conforming raceways. The 60 series is the thinnest of the standard sections, so on a 65 mm shaft this bearing takes up only 17.5 mm of radial space per side and 18 mm of axial length.

P4 tolerance is what separates this from a general-purpose 6013. Bore and outside diameter deviations, radial runout and side-face runout are all held to a fraction of the standard-class limits, which is what a ground spindle position, a precision index drive or an instrument-grade rotary axis needs to hold its geometry.

Internal Clearance: CN. Normal radial internal clearance, the correct choice where the shaft fit is a light interference and the bearing runs close to ambient temperature.

Dynamic Load Rating: 33.5 kN. Static Load Rating: 25.2 kN. The dynamic figure is the load that gives one million revolutions of basic rating life; the static figure is the load that produces a permanent deformation of 0.0001 of the ball diameter at the most heavily loaded contact.

Mounting data

Shaft Abutment Diameter (da): 71.5 to 73 mm. Housing Abutment Diameter (Da max): 93.5 mm. Maximum Abutment Fillet Radius (ra max): 1 mm. Bearing Chamfer (r min): 1.1 mm.

Ball Complement: 15 balls. Ball Diameter: 10.319 mm (0.406 in).

Quantity and configuration

Unit Quantity: 1 Pc. One open bearing, supplied as an individual bearing rather than a matched set.

Interchange guidance

The envelope is the ISO 6013 standard 65 x 100 x 18 mm, so it shares boundary dimensions with 6013, 6013-2Z, 6013-2RS and 6013 C3 from every maker. The Fafnir cross MM9113K belongs to the 9100K spindle deep-groove family, whose 9113 size maps to the same 65 x 100 x 18 mm envelope. A standard-class 6013 fits the same seats; the P4 tolerance and the ground running accuracy are what this listing carries over one.
