Decoding NTN 239/1060K
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- /1060Bore
- Bore: 1060 mm.
- KSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
239/1060 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 239/1060K measures 1060 mm across the bore and 1400 mm across the outside diameter; its width is 250 mm (1060 x 1400 x 250 mm).

Spherical roller bearings in the NTN K series are self-aligning, two-row components built to carry high radial loads together with axial loads in either direction, and they keep working when the shaft and housing are not perfectly aligned. This makes them a practical choice for heavy equipment where shaft deflection or mounting error is a real condition. MR Industrial Accessories LLC supplies this line to industrial users across the United States and in several Latin American countries.
Reading the designation is the first step. The number identifies the series and the bore size in millimeters, while the K suffix signals a tapered bore with a 1:12 taper. In 239/500K, 239/530K and 239/560K, the bore diameters are 500 mm, 530 mm and 560 mm respectively. That tapered bore is what allows mounting on a tapered shaft or with an adapter sleeve, which simplifies both clearance adjustment and later disassembly.
Typical service is in steel, cement, mining, paper, cranes and heavy transmission work. Large gearboxes, mills, rotary kilns and conveyors are common homes for these bearings. Because they tolerate misalignment, they suit long shafts that deflect under load, a situation where rigid bearing types cannot follow the movement.
Selection should consider radial and axial load, rotation speed and the surrounding environment. In dusty or humid locations, sealing deserves attention, and sealed or shielded configurations may be the better choice. Grease or oil lubrication both apply, and internal clearance has to match the duty. When the bore is tapered, correct tightening of the adapter sleeve is what produces the right residual clearance.
On interchangeability, NTN K series spherical roller bearings correspond to other brands using the same ISO designation, such as SKF, FAG or NSK, as long as dimensions and suffixes agree. For a replacement, confirm the full part number and tolerances. If you are working from another brand's reference, our team can point you to the compatible option.

Frequently asked questions
- NTN 239/1060K bearing: what are its dimensions?
- NTN 239/1060K measures 1060 mm across the bore and 1400 mm across the outside diameter; its width is 250 mm (1060 x 1400 x 250 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 239/1060.
- What does the K suffix indicate on these bearings?
- It indicates a tapered bore with a 1:12 taper. The bearing can then be mounted on a tapered shaft or with an adapter sleeve, which makes internal clearance adjustment and disassembly easier.
- Can these bearings replace those from other brands?
- Yes, NTN K series spherical roller bearings are interchangeable with bearings from other brands that follow the same ISO designation, such as SKF, FAG or NSK, provided dimensions and suffixes match. Verify the complete part number.
- How do I request a quote for a bearing from this series?
- Send the complete part number, for example 239/500K, by WhatsApp or email. If you do not have the part number, send the dimensions or the equipment model and we will help you source it.
