116756 Bearing Dimensions
| Item | Specification |
|---|---|
| Designation | 116756 |
| Bearing type | Four-point contact ball bearing |
| Bore diameter d | 280 mm |
| Outside diameter D | 419.5 mm |
| Overall width B | 65 mm |
These principal dimensions identify the catalogue envelope. The mating ring dimensions, contact geometry and required clearance should be checked against the drawing for your assembly.
Check 419.5 mm Before Selecting a Replacement
The ZQM catalogue lists 116756 separately from 116156. Both have a 280 mm bore and a 65 mm width, but the listed outside diameters are 419.5 mm and 420 mm respectively. That 0.5 mm difference matters at the housing seat; the two references should not be treated as interchangeable.
Use the original designation together with the drawing revision when requesting a replacement. A matching bore alone does not confirm the fit, ring arrangement or axial location.
Four-Point Contact Design
Four-point contact ball bearings can accommodate axial loads in either direction within one bearing arrangement. Their suitability for combined loading depends on the design and the actual ratio of axial to radial load. Do not select one solely from its outside dimensions.
The supplied photograph shows the separated ring and ball-and-cage assembly. Keep the matched parts together and confirm the ring orientation, shoulder arrangement and assembly procedure before installation.
Information Needed for a 116756 Bearing Quote
- Quantity and the full marking on the existing bearing.
- A drawing showing the 419.5 mm housing seat and the axial locating surfaces.
- Required clearance or preload, precision requirements and operating speed.
- Axial and radial loads, lubrication method and delivery destination.

116756 Selection Questions
Can I replace it with a 280 × 420 × 65 mm bearing?
Not on dimensions alone. The catalogue outside diameter for 116756 is 419.5 mm. Confirm the housing fit and the complete bearing drawing before approving a substitute.
Does the number specify the clearance or accuracy?
No clearance or precision class is specified on this page. Include those requirements in your enquiry rather than assuming they follow from the basic designation.
Are load ratings and speed limits available?
Ask for the technical data for the actual offered configuration. This page does not substitute another manufacturer’s ratings for ZQM product data.
