How to read TIMKEN 23940EM
- 239Series
- Spherical roller bearings, 239 series. For the same bore, each series has a different outside diameter and width.
- 40Bore
- 200 mm bore: 40 × 5.
- EMSuffix
- TIMKEN suffix: it defines the variant (sealing, cage, internal clearance or other features).
23940 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

TIMKEN EM series spherical roller bearings are components designed to withstand high radial loads and angular misalignment between shaft and housing. Their double-row roller design and spherical outer raceway allow them to adapt to shaft deflection without losing load capacity. They are used in equipment subject to vibration, shock or assemblies where perfect alignment is not guaranteed. MR Accesorios Industriales supplies this line as a brand in Buenos Aires, Argentina.
The EM series designation consists of a basic five-digit number that indicates size and load capacity, followed by the EM suffix. For example, 22206EM, 22208EM and 22212EM correspond to spherical roller bearings with different dimensions. The EM suffix identifies a machined brass cage design, suitable for demanding applications. Numbers in the 222 series indicate medium-section spherical roller bearings, while other series such as 223 have higher capacity. To choose the correct part number, it is essential to know the shaft diameter, the load and the operating conditions.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, mining, paper and food processing. They are found in equipment such as conveyor belts, mills, crushers, vibrating screens, industrial fans and paper machines. Their ability to withstand misalignment makes them ideal for assemblies where shafts may deflect or where supports are not perfectly aligned. They are also used in applications with combined radial and axial loads, although their main strength is radial load.
To select the right bearing, take into account the radial and axial load it must withstand, the rotation speed, the type of lubrication and the environmental conditions. The EM suffix indicates a machined brass cage, which offers greater strength and heat dissipation than stamped steel cages. It is important to verify the correct internal clearance for the application; excessive clearance can cause vibration and insufficient clearance can cause overheating. During mounting, ensure correct alignment and use suitable tools to avoid damage to the rollers and raceways. Lubrication must be the one recommended by the manufacturer and must be kept clean.
As for equivalences and interchangeability, spherical roller bearings from different brands can be interchanged if they share the same dimensions and basic designation. For example, a 22206EM bearing from another brand can replace the TIMKEN one if tolerances and internal clearance are equivalent. However, it is advisable to verify the technical specifications of each manufacturer, since there may be differences in load capacity, cage or heat treatment. MR Accesorios Industriales can advise you on the compatible alternative for your equipment.

Frequently Asked Questions
- What are the dimensions of the TIMKEN 23940EM bearing?
- The TIMKEN 23940EM bearing has a 200 mm bore, a 280 mm outside diameter and a 60 mm width (200 x 280 x 60 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23940.
- What does the EM suffix mean on a TIMKEN bearing?
- The EM suffix indicates that the bearing has a machined brass cage, which gives it greater strength and heat dissipation capacity. It is a design suitable for applications with high loads or moderate speeds.
- How do I choose the right spherical roller bearing?
- To choose correctly, you need to know the shaft diameter, the radial and axial load, the rotation speed and the lubrication conditions. With that data, we can quote the exact part number you need.
- Can I replace a bearing from another brand with a TIMKEN one?
- Yes, if the dimensions and basic designation match. It is important to verify tolerances and internal clearance. At MR we advise you to find the alternative compatible with your equipment.
