Rolling Mill Bearings
Rolling mill bearings manufacturer — four-row tapered roller bearings, four-row cylindrical roller bearings, backing bearings for Sendzimir mills. Bearing block and chock assembly solutions for hot strip, cold rolling, plate, bar & wire mills.
Technical Overview
Rolling mill bearings are precision-engineered components designed specifically for the extreme demands of steel and metal rolling operations. These bearings must withstand very heavy loads, high temperatures, shock impacts, and continuous operation cycles while maintaining tight dimensional tolerances. ANDE specializes in manufacturing rolling mill bearings including backing bearings for Sendzimir cluster mills, four-row cylindrical roller bearings for work rolls and backup rolls, and four-row tapered roller bearings for rolling mill applications requiring combined radial and axial load support. Our rolling mill bearings are manufactured from premium bearing steel with special heat treatment processes, precision-ground raceways, and robust cage designs to ensure reliable performance in the harsh operating environment of hot and cold rolling mills. We supply complete rolling mill bearing assemblies — including bearings, bearing blocks (housings), and bearing chocks — for plate mills, strip mills, section mills, bar & wire rod mills, and tube mills across the global steel industry. We provide interchangeable size and performance benchmarking solutions for bearings from major international manufacturers; all trademarks belong to their respective owners.

Rolling Mill Applications
Hot Rolling Mills
Four-row cylindrical and tapered roller bearings for work roll and backup roll chock assemblies in hot strip mills operating at temperatures up to 300°C. Our bearings withstand heavy shock loads from slab entry and continuous thermal cycling.
Cold Rolling Mills
Backing bearings for Sendzimir 20-high cluster mills and four-row bearings for tandem cold rolling mills producing thin-gauge stainless steel, silicon steel, and aluminum strip with tight thickness tolerances.
Plate Mills
Heavy-duty four-row tapered roller bearings for plate mill roll assemblies handling extreme radial and axial loads during thick plate rolling of carbon steel, alloy steel, and stainless steel plates.
Bar & Wire Rod Mills
Compact four-row cylindrical roller bearings and spherical roller bearings for high-speed bar and wire rod mill stands where space constraints and high rotational speeds are critical factors.
Section Mills
Rolling mill bearings for H-beam, angle, channel, and rail section mill stands requiring bearings that handle combined radial loads and axial thrust from asymmetric roll profiles.
Rolling Mill Bearing Selection Guide
Selecting the right bearing for your rolling mill application depends on several key factors. Our engineering team provides free consultation to help you choose the optimal bearing configuration.
Load Type & Magnitude
Determine whether your application requires primarily radial load support (four-row cylindrical), combined radial and axial load support (four-row tapered), or cluster mill backup support (backing bearings).
Speed & Temperature
Hot rolling mills require bearings rated for elevated temperatures with appropriate clearance and lubrication. Cold rolling mills prioritize precision at higher rotational speeds.
Lubrication & Sealing
Choose between oil or grease lubrication based on speed and temperature. Effective sealing is critical to prevent scale, water, and coolant ingress in the mill environment.
Clearance & Preload
Internal clearance must be specified to account for thermal expansion, interference fit, and operating loads. Incorrect clearance is a leading cause of premature rolling mill bearing failure.
Bearing Block & Chock Compatibility
The bearing must fit precisely within the bearing block (housing) or bearing chock assembly. We supply bearings matched to your existing chock dimensions or as complete bearing assemblies.
Frequently Asked Questions
What types of rolling mill bearings does ANDE manufacture?
ANDE manufactures four-row tapered roller bearings, four-row cylindrical roller bearings, and backing bearings (Sendzimir type) for rolling mill applications. We supply bearings for work rolls, backup rolls, and intermediate rolls across hot strip mills, cold rolling mills, plate mills, section mills, and bar & wire rod mills.
Can ANDE rolling mill bearings replace SKF, Timken, or NSK equivalents?
Yes. We provide interchangeable size and performance benchmarking solutions that can directly replace equivalent bearings from major international manufacturers. Our bearings match the same dimensional standards, load ratings, and precision grades. All trademarks mentioned belong to their respective owners.
Do you supply complete rolling mill bearing assemblies?
Yes. We can supply bearings individually or as complete rolling mill bearing assemblies including the bearing, bearing block (housing), and bearing chock, pre-assembled and ready for installation in your mill stand.
What is the lead time for rolling mill bearings?
Standard rolling mill bearing sizes: 4-6 weeks from order confirmation. Non-standard or large-bore custom bearings: 6-10 weeks. We can arrange expedited production for urgent mill shutdown situations.
How do I select between four-row cylindrical and four-row tapered roller bearings?
Four-row cylindrical roller bearings provide maximum radial load capacity and are ideal when axial loads are minimal. Four-row tapered roller bearings handle both radial and significant axial thrust loads simultaneously, making them suitable for mill stands with axial positioning requirements. Our engineers can help you determine the optimal type for your application.
What bearing clearance should I specify for a hot rolling mill?
Hot rolling mill bearings typically require C3 or C4 clearance to account for thermal expansion at operating temperatures of 80-150°C. The exact clearance depends on bearing size, operating temperature, and fit interference. Contact our engineering team with your operating conditions for a specific recommendation.
Do you supply rolling mill bearing blocks and chocks?
We supply bearings designed to fit standard bearing block and chock assemblies. For customers requiring complete solutions, we can provide bearings matched to your specific bearing block or chock dimensions, or recommend compatible housing configurations.
What is the price range for rolling mill bearings?
Rolling mill bearing pricing depends on type, size, precision grade, and quantity. As a factory-direct manufacturer, we offer competitive pricing compared to trading companies. Contact us with your bearing model number or drawing for a specific quotation within 24 hours.
