Intermediate Roll Bearings for Rolling Mills

Requirements

Intermediate Roll Bearing Requirements

High Radial Load & Rigidity

Intermediate roll bearings support rolling forces transferred between the work rolls and backup rolls while helping maintain roll-system rigidity.

Compact Mounting Arrangement

Six-high and multi-roll mill designs often provide limited radial and axial installation space around the intermediate roll neck.

Rotational Accuracy & Low Runout

Stable intermediate roll guidance supports strip thickness, flatness and surface quality, especially in precision cold rolling applications.

Roll Shifting & Axial Guidance

Some intermediate rolls move axially for profile control, requiring a bearing arrangement that accommodates shifting, thermal movement and axial location.

Speed, Lubrication & Reliability

Rolling speed, friction, lubricant cleanliness, cooling and contamination control influence temperature and bearing service life.

Products

Recommended Bearing Types

Double Row Cylindrical Roller Bearings

Compact, high-rigidity and high-radial-load solution for many intermediate roll positions in six-high and precision rolling mills.

Four-Row Cylindrical Roller Bearings

High radial load capacity for larger intermediate roll and roll neck positions requiring separable mounting and stable support.

Double Row Tapered Roller Bearings

Integrated radial and axial load support for compact intermediate roll arrangements requiring accurate axial guidance.

Backing Bearings

Support-roll bearings for cluster and multi-roll mills where uniform support contributes to strip thickness and surface consistency.

Thrust Ball Bearings

Separate axial locating and roll-shift support where radial and axial functions are carried by different bearing positions.

FAQ

Intermediate Roll Bearings for Rolling Mills FAQ

Please provide the mill type, complete roll arrangement, intermediate roll position, bearing number, roll neck dimensions, radial and axial loads, speed, shifting stroke, precision requirement, lubrication, quantity and drawing if available.

Double row cylindrical roller bearings, four-row cylindrical roller bearings and double row tapered roller bearings are common directions. The final arrangement depends on mounting space, load direction, roll shifting and axial location.

Please provide the shifting stroke, frequency, axial force, roll neck and chock drawing, locating and non-locating arrangement, speed and lubrication details.

The bore diameter range is generally from 100mm to 1600mm. Custom dimensions can be reviewed according to drawings and application requirements.

Yes. Please send the original brand, bearing number, dimensions, precision requirement, complete roll-system drawing and operating information for compatibility review.
