These d×D×B envelopes at a 49.2125 mm bore are shared by several series or brands — the starting point for a dimensional cross reference:
Selecting a 49.2125 mm bore bearing
The bore fixes the shaft, not the bearing capacity. At 49.2125 mm the catalog spans 90–90 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 49.2125 mm bore?
This index lists 11 verified bearing models with a 49.2125 mm (1.938 in) bore across 1 bearing type, from 90 to 90 mm outside diameter. Open any model for the full specification table, seal/clearance options and graded cross references.
How do I choose between the 90–90 mm OD options for a 49.2125 mm shaft?
On a fixed 49.2125 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 49.2125 mm bearings?
A 49.2125 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). Bore diameters below 20 mm follow the 10/12/15/17 mm exception table rather than code × 5.
