241Series
Spherical roller bearings, 241 series. Series differ in outside diameter and width even when the bore is the same.
/710Bore
Bore: 710 mm.
ECAK30/C3W33Suffix
SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.

241/710 is the standard ISO basic designation, which sets the bearing type, series and bore.

Description

SKF 241/710 ECAK30/C3W33 measures 710 mm across the bore and 1150 mm across the outside diameter; its width is 438 mm (710 x 1150 x 438 mm).

When shafts flex or supports are not perfectly aligned, SKF spherical roller bearings keep equipment running. Their two rows of rollers and spherical outer raceway let the bearing self-align while carrying heavy radial loads and axial loads in both directions. These bearings are a common choice for conveyors, mills, pumps and gearboxes, where dependable operation under difficult conditions matters. MR Industrial Accessories LLC supplies this line and helps you select the correct variant.

The part number is built from blocks that describe the bearing's features. ECA points to an optimized design that uses a stamped steel cage with roller guidance. K means a tapered bore, and the number 30 after it specifies a 1:12 taper. C3 sets internal radial clearance above normal. W33 tells you the outer ring has a lubrication groove and three holes. Large-size bearings often combine these attributes, so reading the code quickly tells you what you are working with.

These bearings suit equipment where loads are heavy and misalignment or shaft deflection can occur. Typical installations include mining conveyors, cement mills, crushers, high-flow centrifugal pumps, speed reducers and paper machines. Industrial fans and continuous process lines also use them, because the ability to handle combined loads helps avoid unplanned stops.

Selection depends on load size and direction, rotation speed and the operating environment. Choose C3 clearance when thermal expansion of the shaft or interference fits are expected. The W33 groove and holes simplify relubrication, particularly where contamination is present. During mounting, check initial alignment and how the inner ring is secured if the bore is tapered. Use a lubricant that matches the temperature and speed; both over- and under-lubrication can cut service life.

Bearings from different manufacturers can often be interchanged if the main dimensions, internal clearance and version details such as taper, grooves and cage match. Suffix meanings are not always the same across brands, so verify each code rather than assuming. MR Industrial Accessories LLC can advise on interchangeability and source the SKF reference you need.

Frequently asked questions

SKF 241/710 ECAK30/C3W33 bearing: what are its dimensions?
SKF 241/710 ECAK30/C3W33 measures 710 mm across the bore and 1150 mm across the outside diameter; its width is 438 mm (710 x 1150 x 438 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 241/710.
What does C3 mean on a spherical roller bearing?
C3 indicates internal radial clearance greater than normal. It is specified when the bearing will run at high temperatures or with fits that reduce clearance, such as a tapered shaft mounting. The extra clearance compensates for thermal expansion and helps prevent excessive preload.
When should I choose a tapered bore instead of a cylindrical one?
A tapered bore, shown by the letter K, is used when you need an interference fit that is easy to mount and dismount, or when radial clearance must be adjusted by axial displacement on a sleeve. It is common in applications with rotating shafts and high loads.
How can I tell if another brand's bearing matches the SKF one?
Compare the main dimensions (bore, outer diameter and width), the version type (taper, grooves, cage) and the internal clearance. Suffixes can differ between manufacturers, so do not rely on the code alone. Send us the reference and we will help you verify the equivalence.
