Decoding SKF 240/500 ECA/C3W33
- 240Series
- Spherical roller bearings, 240 series. Series differ in outside diameter and width even when the bore is the same.
- /500Bore
- Bore: 500 mm.
- ECA/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
240/500 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 240/500 ECA/C3W33 measures 500 mm across the bore and 720 mm across the outside diameter; its width is 218 mm (500 x 720 x 218 mm).

SKF spherical roller bearings handle radial and axial loads in both directions and can compensate for misalignment between shaft and housing. They suit heavy-duty equipment where shaft deflection or mounting inaccuracies occur. MR Industrial Accessories supplies this line and offers technical guidance to select the correct execution.
The series designation combines a four- or five-digit basic number with suffixes ECA/C3W33. The basic number indicates size and load capacity; for example, 24088 ECA/C3W33 and 24176 ECA/C3W33 differ in diameter and dimension series. The ECA suffix denotes an internal design with stamped steel cage and cylindrical bore. C3 means internal radial clearance greater than normal. W33 identifies a lubrication groove and holes in the outer ring. These codes let you order the exact bearing for your application.
Typical industries include cement, mining, steel, paper, wind power, and earthmoving. You will find them in crushers, mills, conveyor belts, large centrifugal pumps, industrial fans, and road machinery. Their self-aligning ability makes them suitable for long shafts or shafts subject to deflection, where rigid bearings would suffer stress concentration. They also work in combined-load and moderate-speed applications.
Selection depends on radial and axial load, speed, required internal clearance, and lubrication type. Choose C3 when fits are tight or operating temperature reduces clearance; W33 simplifies relubrication through the outer ring. During mounting, verify initial alignment, seat cleanliness, and heating method to avoid damage. Use lubricant suited to temperature and load, and protect with seals against contamination.
Spherical roller bearings follow international standards for dimensions and tolerances, so different brands are dimensionally interchangeable. However, internal suffixes can vary: the same size may have different cage, clearance, or lubrication designs. Always confirm the complete part number and service conditions before replacing one brand with another.

Frequently asked questions
- SKF 240/500 ECA/C3W33 bearing: what are its dimensions?
- SKF 240/500 ECA/C3W33 measures 500 mm across the bore and 720 mm across the outside diameter; its width is 218 mm (500 x 720 x 218 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 240/500.
- What does the C3 suffix indicate?
- C3 indicates internal radial clearance greater than normal. It is specified for tight fits, temperature differences between rings, or high speeds to prevent clearance from becoming too small during operation.
- What is the purpose of the W33 groove and holes?
- W33 means the outer ring has a lubrication groove and holes, allowing relubrication from the housing without dismounting the bearing. This simplifies maintenance on hard-to-reach equipment.
- How do I request a quote for an SKF bearing?
- Send the complete bearing part number, for example 24088 ECA/C3W33, and the quantity you need via WhatsApp. MR Industrial Accessories will reply with a quote and possible alternatives.
