How to read FAG 238/1060-B-K-MB
- 238Series
- Spherical roller bearings, 238 series. For the same bore, each series has a different outside diameter and width.
- /1060Bore
- 1060 mm bore.
- B-K-MBSuffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
238/1060 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

FAG spherical roller bearings are self-aligning double-row components designed to withstand high radial loads and axial loads in both directions. Their spherical outer raceway and cage allow them to compensate for angular misalignment between shaft and housing, making them ideal for applications with shaft deflection or mountings that cannot guarantee perfect alignment. MR Accesorios Industriales sells this line for mining, cement, steel and other industries that demand robustness and durability.
The designation of these bearings follows a clear scheme. The base number, as in 230/1250-B-K-MB or 238/670-B-K-MB, indicates the size and dimension series. The letter B indicates a modified internal design, with higher load capacity and better lubrication conditions. The letter K indicates a tapered bore (taper 1:12), suitable for mounting on an adapter sleeve or tapered shaft. The suffix MB identifies a machined brass cage, high strength, guided by the inner ring. These variants cover a wide range of requirements.
In Argentine industry, these bearings are used in critical applications: ball and rod mills in mining, rotary kilns and coolers in cement plants, rolling mills in steel plants, paper machines and material handling equipment. Their ability to withstand combined loads and misalignment makes them suitable for long shafts subject to deflection, where other bearing types would fail prematurely. MR Accesorios Industriales sells them to meet these demands.
To select correctly, take into account radial and axial load, rotational speed and environmental conditions. Sealing is key: if there is dust or moisture, consider variants with seals or shields. Lubrication must be adequate, with grease or oil depending on the application. During mounting, check alignment and internal clearance; the tapered bore makes adjustment with an adapter sleeve easier. The brass cage tolerates shocks and vibrations better. Always consult the manufacturer's recommendations for each case.
There are equivalences between brands: spherical roller bearings from other manufacturers with similar designations can be interchanged, but it is essential to verify dimensions, tolerances and load capacity. Not all suffixes match between brands. Therefore, when requesting a quote, provide the complete part number shown on the bearing or on the drawing. At MR Accesorios Industriales we can guide you to find the right option, whether FAG or another brand we sell.

Frequently Asked Questions
- What are the dimensions of the FAG 238/1060-B-K-MB bearing?
- The FAG 238/1060-B-K-MB bearing has a 1060 mm bore, a 1280 mm outside diameter and a 165 mm width (1060 x 1280 x 165 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 238/1060.
- What does the suffix K mean in a FAG bearing?
- The letter K indicates that the bearing has a tapered bore with taper 1:12. This allows it to be mounted on a tapered shaft or with an adapter sleeve, making it easier to adjust internal clearance and secure it.
- How do I choose between an MB brass cage and other cages?
- The machined MB brass cage is robust and better withstands shock loads and vibrations. It is ideal for heavy applications. If the speed is very high, evaluate other options. Contact us on WhatsApp for advice based on your equipment.
- Can I replace a bearing from another brand with a FAG one?
- Yes, as long as dimensions, tolerances and load capacity match. Suffixes may vary between manufacturers. Provide the complete part number and dimensions so we can verify the equivalence before quoting.
