Exact-dimension interchange groups at 75 mm bore
These d×D×B envelopes at a 75 mm bore are shared by several series or brands — the starting point for a dimensional cross reference:
Selecting a 75 mm bore bearing
The bore fixes the shaft, not the bearing capacity. At 75 mm the catalog spans 95–190 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 k5 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 75 mm bore?
This index lists 38 verified bearing models with a 75 mm (2.953 in) bore across 5 bearing types, from 95 to 190 mm outside diameter. Open any model for the full specification table, seal/clearance options and graded cross references.
How do I choose between the 95–190 mm OD options for a 75 mm shaft?
On a fixed 75 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 75 mm bearings?
A 75 mm bore on a rotating inner ring normally uses a k5 shaft seat with an H7 housing bore (verify against the catalogue for heavy or stationary-ring duty). In the ISO designation system 75 mm is bore code 15 (code × 5), so a 62-series bearing with this bore is the 6215.
