Decoding FAG 239/1060-K-MB1
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- /1060Bore
- Bore: 1060 mm.
- K-MB1Suffix
- FAG 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

The FAG spherical roller bearing 239/1060-K-MB1 is a self-aligning bearing with two rows of spherical rollers. It handles radial and axial loads in both directions and compensates for angular misalignment between shaft and housing. This makes it suitable for equipment where shaft deflection or mounting errors occur, such as industrial drives, process machines and mining equipment.
The part number breaks down into meaningful blocks. The numeric prefix 239/1060 identifies the dimension series. The K suffix means a tapered bore with a 1:12 taper, so the bearing can be mounted on a tapered shaft or with an adapter sleeve. MB1 denotes the machined brass cage and the inner ring treatment. Reading these suffixes correctly is essential when ordering a replacement.
In US plants, these bearings are found in gear reducers and gearboxes, conveyor rollers, mills and crushers, high-flow pumps, and steel and cement equipment. They also appear in road machinery and oil & gas applications. Their self-aligning capability suits long shafts or shafts subject to deflection, where other bearing types cannot tolerate angular error.
Selection depends on radial and axial load, rotation speed and lubrication method. Seals or protective plates are chosen according to the environment: dust, moisture or particles call for additional protection. The MB1 machined brass cage is common in demanding applications. For tapered bore mounting, check radial clearance and secure the adapter sleeve properly; careful alignment helps extend service life.
Spherical roller bearings follow interchangeable dimension standards, so the same basic part number may exist across different brands. When requesting a quote, provide the complete part number with suffixes, the operating conditions and whether a cylindrical or tapered bore version is required. MR Industrial Accessories supplies FAG and can help you identify the variant that fits your equipment.

Frequently asked questions
- FAG 239/1060-K-MB1 bearing: what are its dimensions?
- FAG 239/1060-K-MB1 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 mean in the designation?
- The letter K indicates a tapered bore with a 1:12 taper. This allows mounting directly on a tapered shaft or with an adapter sleeve, which simplifies radial clearance adjustment and dismounting.
- How do I choose between cylindrical and tapered bore?
- A cylindrical bore is used when the shaft is cylindrical and mounting is by press fit or with a lock nut. A tapered bore simplifies mounting and clearance adjustment on shafts with an adapter sleeve. The choice depends on equipment design and maintenance practices.
- What should I consider for lubrication?
- Lubrication depends on speed, temperature and load. Generally, grease or oil is used depending on the operating regime. Follow the manufacturer's recommendations and check lubricant condition at each maintenance interval to avoid premature failures.
