Exact-dimension interchange groups at 950 mm bore

These d×D×B envelopes at a 950 mm bore are shared by several series or brands — the starting point for a dimensional cross reference:

Selecting a 950 mm bore bearing

The bore fixes the shaft, not the bearing capacity. At 950 mm the catalog spans 1150–1600 mm outside diameter: the light sections suit compact housings and moderate duty, while the larger ODs use bigger rolling elements and carry substantially more load. Select first by the required dynamic load rating C for the calculated L10 life, then by available radial space.

For a rotating inner ring a m6 shaft seat with an H7 housing is the usual starting point; an interference fit plus thermal growth consumes internal clearance, so C3 is the common industrial default rather than CN. Sealed variants (-2RS, -ZZ) trade a small amount of speed for contamination protection and maintenance-free operation — compare the sealed and open versions of the same envelope before substituting one for the other.

Frequently asked questions

What bearings have a 950 mm bore?

This index lists 14 verified bearing models with a 950 mm (37.402 in) bore across 5 bearing types, from 1150 to 1600 mm outside diameter. Open any model for the full specification table, seal/clearance options and graded cross references.

How do I choose between the 1150–1600 mm OD options for a 950 mm shaft?

On a fixed 950 mm bore, a smaller outside diameter means a lighter section for limited housing space and moderate load; a larger OD with a wider ring carries more radial and axial load and lasts longer at the same duty. Compare the C dynamic load rating in each model table, then match seal type, internal clearance (CN/C3/C4) and precision class to the actual mounting and operating temperature.

What shaft fit and bore code apply to 950 mm bearings?

A 950 mm bore on a rotating inner ring normally uses a m6 shaft seat with an H7 housing bore (verify against the catalogue for heavy or stationary-ring duty). In the ISO designation system 950 mm is bore code 190 (code × 5), so a 62-series bearing with this bore is the 62190.
