Decoding TIMKEN 22310EM
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- EMSuffix
- TIMKEN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22310 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
TIMKEN 22310EM measures 50 mm across the bore and 110 mm across the outside diameter; its width is 40 mm (50 x 110 x 40 mm).

TIMKEN EM series spherical roller bearings handle high radial loads and angular misalignment between shaft and housing. The double-row roller design with a spherical outer raceway adapts to shaft deflection while maintaining load capacity, making these bearings suitable for equipment subject to vibration, shock, or imperfect alignment.
The EM suffix denotes a machined brass cage, which provides strength and heat dissipation for demanding applications. Part numbers such as 22206EM, 22208EM, and 22212EM follow a basic five-digit system: the first digits indicate the series and size, while the suffix identifies the cage type. The 222 series covers medium-section bearings; other series like 223 offer higher capacity. To select the correct bearing, you need the shaft diameter, load, and operating conditions.
These bearings are found in conveyor belts, mills, crushers, vibrating screens, industrial fans, and paper machines. Their ability to accommodate misalignment suits assemblies where shafts deflect or supports are not perfectly aligned. They also handle combined radial and axial loads, though radial load is their primary strength. Industries such as metallurgy, cement, mining, paper, and food processing rely on them.
When selecting a bearing, consider radial and axial loads, rotation speed, lubrication type, and environmental conditions. The machined brass cage of the EM suffix offers greater strength and heat dissipation than stamped steel cages. Verify internal clearance: too much can cause vibration, too little can lead to overheating. During mounting, ensure proper alignment and use suitable tools to avoid damaging rollers and raceways. Keep lubrication clean and as recommended.
Spherical roller bearings from different brands can be interchanged if dimensions and basic designation match. For example, a 22206EM from another manufacturer may replace the TIMKEN version if tolerances and internal clearance are equivalent. However, always verify technical specifications, as load capacity, cage, or heat treatment may differ. MR Industrial Accessories can advise on a compatible alternative for your equipment.

Frequently asked questions
- TIMKEN 22310EM bearing: what are its dimensions?
- TIMKEN 22310EM measures 50 mm across the bore and 110 mm across the outside diameter; its width is 40 mm (50 x 110 x 40 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22310.
- What does the EM suffix mean on a TIMKEN bearing?
- The EM suffix indicates a machined brass cage, which offers greater strength and heat dissipation than stamped steel cages. It is suitable for high-load or moderate-speed applications.
- How do I choose the right spherical roller bearing?
- You need the shaft diameter, radial and axial loads, rotation speed, and lubrication conditions. With that information, we can quote the exact part number you need.
- Can I replace a bearing from another brand with a TIMKEN one?
- Yes, if dimensions and basic designation match. Verify tolerances and internal clearance. We can help you find a compatible alternative for your equipment.
