The 5310S is a angular contact ball bearing supplied by DALUO under our own designation. It is dimensioned to the 50x110x44.4 mm envelope (bore 50 mm, outer 110 mm, width 44.4 mm). Each unit is produced to the original mounting and load envelope, so it drops straight into the applications the 5310S was designed for.

Why source the 5310S from DALUO
- Factory-direct supply. DALUO is a bearing and seal manufacturer with our own production and inspection lines, so you buy without middlemen.
- Dimensional traceability. Bore, outer diameter and width are verified against the 50x110x44.4 mm specification before packing.
- Flexible order size. Sample quantities for validation, and bulk volumes for production programmes.
- Consistent re-orders. The same designation arrives with the same tolerances, order after order.
Applications
The 5310S is commonly fitted where a angular contact ball bearing has to carry combined radial and axial load in a compact space: gearboxes, pumps, motors, conveyors, agricultural machinery and general industrial drives. If you are replacing an existing unit, confirm the shaft and housing fits from the table above.
