The 241 series belongs to the relatively wider cross-section and higher load-carrying capacity series among spherical roller bearings (compared with the 240 series of the same bore diameter). If a tapered bore design is adopted, the taper is 1:30 (suffix K30), making it convenient to mount on cylindrical shaft through adapter sleeve or withdrawal sleeve. During selection, it is necessary to confirm whether it is applicable based on the specific equipment load characteristic, speed, and alignment condition.
We can assure supply orginal 3Y spherical roller bearing 241 Series and related parts series with ideal service. If you have any requirement,just let us know.
The application fields of the 241 series spherical roller bearings are mainly concentrated in heavy-load industrial occasion with shaft deflection or installation misalignment, and medium-to-low speed operation. Its most prominent application is in roller presses and crushing equipment in the mining and cement industry, and it is also widely used in traditional heavy industry fields such as papermaking, metallurgy, and vibrating screening.
Mining and Cement
This is the most representative application scenario for the 241 series. This series of bearing is commonly used in roller presses (mainly for grinding cemen and raw material) and crusher. These working condition involve extremely high load, harsh environment, and risks of contaminant ingress. For 241 series with bore diameter of 500 mm and above, some manufacturers (such as Schaeffler) have adopted end-profiled rollers, which can reduce edge contact stress caused by abrasive wear by at least 20%, in order to improve durability in mining and cement environment.
Metallurgy and Metal Processing
Suitable for equipment such as continuous casting machine and rolling mill (such as gearbox bearing housing and rolling roll). These occasions involve heavy load, impact, and possible shaft deflection, and the self-aligning capability and high load-carrying characteristic of the 241 series are well matched.
Papermaking and Printing Machinery
Papermaking machine and printing presse are classic application for spherical roller bearings. The 241 series can be used to withstand radial load and certain axial load while compensating for misalignment caused by long shaft or frame deformation.
Vibrating Screens and Vibrating Equipment
In equipment such as vibrating screen and exciter that involve strong vibration and impact load, the 241 series is widely adopted due to its impact resistance and self-aligning capability.
Other Heavy Industry Scenarios
These include mining equipment, blower and fan, rubber and plastic molding equipment, pump and compressor, gear transmission and reducer, and bulk material conveying equipment, etc.
