Tapered Roller Bearings are selected when an assembly calls for supporting a rotating shaft and carrying its radial and axial loads with low friction. This application guide to the ISO / DIN type covers concrete end-uses, the specification checklist, correct installation, and where an alternative fastener performs better. Stocked across roughly 20 mm to 80 mm, they cover heavy and structural work.
Typical Applications for Tapered Roller Bearing — ISO / DIN (Series 116)
The most common settings where these are specified:
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
How to Specify Tapered Roller Bearing — ISO / DIN (Series 116) for Your Application
- Size: Select on bore diameter, and confirm it against the mating feature in the assembly. This product spans 20 mm–80 mm; check the full table below for the exact dimensions of each size.
- Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This is a trade-series article rather than one covered by a published dimensional standard, so dimensions can differ between manufacturers. Quote the dimensions you need — or the part you are replacing — rather than a standard number.
Where Tapered Roller Bearing — ISO / DIN (Series 116) Are Not the Right Choice
Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.

Need a tapered roller bearing outside the standard range?
A non-standard bearing & bushing is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
