Decoding NTN 30216U3EB
- 302Series
- Tapered roller bearings, 302 series. Series differ in outside diameter and width even when the bore is the same.
- 16Bore
- Bore 80 mm (16 × 5).
- U3EBSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
30216 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 30216U3EB measures 80 mm across the bore and 140 mm across the outside diameter; its total width is 28.25 mm (80 x 140 x 28.25 mm).

NTN tapered roller bearings are built to carry radial and axial loads in one direction. The tapered rollers make line contact, which helps distribute load in combined-load applications. You will find them in gear reducers, wheel shafts, agricultural equipment and other industrial machinery. MR Industrial Accessories supplies these bearings and can help you confirm the right part number for your equipment.
The part number tells you a lot if you know how to read it. In codes such as 30216U3EB and 30217U3EB, the 302 prefix points to the single-row tapered roller series, while U3 and EB are suffixes that identify specific internal design and tolerance characteristics. If you are unsure what a code means, our team can walk you through it.
These bearings show up in many types of equipment: gearboxes and speed reducers, road and agricultural machinery, material handling systems, machine tool spindles and conveyor rollers. Their ability to take combined loads makes them a common choice where precision and durability matter.
Selection depends on the radial and axial load the bearing will see, the rotation speed and the operating environment. Correct mounting calls for careful alignment and proper lubrication, because tapered rollers are sensitive to mounting errors. Sealing is equally important; pick the seal type based on contamination levels and working temperature. Poor mounting can shorten bearing life significantly.
Equivalent bearings exist across brands, but always verify exact dimensions and tolerances. If you have a code from another manufacturer, we can help you find the NTN equivalent. It is best to check with our technical team before replacing a bearing to confirm compatibility and performance.
