Decoding SKF 23120-2CS2/VT143
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 20Bore
- Bore 100 mm (20 × 5).
- 2CS2/VT143Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23120 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23120-2CS2/VT143 measures 100 mm across the bore and 165 mm across the outside diameter; its width is 52 mm (100 x 165 x 52 mm).

SKF spherical roller bearings are self-aligning, double-row components built for high radial loads and angular misalignment. The 2CS5/VT143 variant comes with integral sealing and factory-applied grease, which simplifies mounting and supports service life in demanding environments. Typical applications include mining, cement, steel and power transmission equipment.
The part number tells you the series, size and features. In 22228-2CS5/VT143, the 222 series indicates a 140 mm bore. The 2CS5 suffix means contact seals on both sides, and VT143 identifies the high-temperature grease filled at the factory. In 24032-2CS5/VT143, the 240 series denotes a design with higher load capacity and lower section height. Reading these codes helps you order the exact replacement.
These bearings handle heavy loads, vibration and contaminated conditions. They are common in cement mills, vibrating screens, mining conveyors, paper machines, industrial fans and steel equipment. The self-aligning ability compensates for mounting errors or shaft deflection, which reduces maintenance needs. They also appear in gearboxes and power transmissions running at moderate speeds under high load.
Selection depends on radial and axial load, speed and environment. The 2CS5 seal keeps out dust and moisture, but for submerged or water-heavy service, evaluate other sealing options. VT143 is a lithium complex grease rated to 150 °C; if operating temperature differs, regreasing may be required. During mounting, align carefully and avoid impacts on the rings, as these are precision components.
When replacing, you may find equivalents from other manufacturers. Dimensions can match, but suffixes and heat treatment may differ. We can advise on interchangeability, though the final choice should follow the equipment specifications. If unsure, send us the original code and application details.

Frequently asked questions
- SKF 23120-2CS2/VT143 bearing: what are its dimensions?
- SKF 23120-2CS2/VT143 measures 100 mm across the bore and 165 mm across the outside diameter; its width is 52 mm (100 x 165 x 52 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23120.
- What does the suffix 2CS5 mean on an SKF bearing?
- The 2CS5 suffix indicates contact seals on both sides. These seals retain grease and block contaminants, which helps extend service life in dirty or humid environments.
- Can the VT143 grease be replaced by another?
- VT143 is a factory lubrication for high temperatures. If you need to regrease, consult the manufacturer's specifications. Do not mix greases with different bases without verifying compatibility, as performance could be affected.
- How do I order the correct bearing for my machine?
- Send the complete code from the original bearing via WhatsApp, along with a photo if possible. That way we can identify the series, sealing and lubrication, and offer the right option for your equipment.
