Hot Rolling Mill Bearings FC3045120

Hot Rolling Mill Bearings FC3045120: Four-Row Cylindrical Roller Bearing for Heavy-Duty Rolling Mills

When your steel generation requests most extreme spiral stack capacity and negligible downtime, Hot Rolling Mill Bearings FC3045120 delivers the designing accuracy you require. This four-row round and hollow roller bearing is particularly planned for roll necks and drums in metallurgical rolling plants. Built to withstand extraordinary stun loads amid the steel gnawing prepare and warm push from high-temperature operations, this distinguishable bearing plan empowers quick mounting and getting off. Your process operations advantage from diminished upkeep time and expanded generation effectiveness. Our 30 a long time of bearing industry skill guarantees solid execution in the harshest steel fabricating environments.

Design Features and Working Principle

The FC3045120 utilizes a distinguishable plan where internal and external ring gatherings can be mounted autonomously. Four columns of round and hollow rollers convey enormous spiral loads equitably over the raceway surfaces. Each roller highlights a logarithmic profile to anticipate edge stretch concentration beneath overwhelming loads or slight misalignment.

The squeezed steel cage guides the rollers whereas keeping up appropriate dividing. This arrangement gives direct contact between rollers and raceways, empowering predominant stack dispersion compared to point-contact ball orientation. The distinguishable plan permits obstructions fits on roll necks whereas encouraging support access.

During operation, the bearing obliges warm extension of the roll neck relative to the chock lodging. This warm recompense avoids authoritative and keeps up legitimate inner clearance all through temperature cycles.

Performance Advantages in Rolling Mill Applications

Superior Load Handling

Four-row construction delivers exceptional radial load capacity for work roll and backup roll applications. The bearing withstands shock loads generated during steel biting and maintains dimensional stability under continuous heavy loads.

Thermal Resistance

High-purity bearing steel construction with special heat treatment enables operation at temperatures up to 500°C. The material retains hardness and dimensional stability when exposed to roll coolants and radiant heat from steel slabs.

Rapid Maintenance

Separable design reduces roll change time significantly. Inner rings remain on roll necks while outer assemblies can be pre-assembled in chocks, minimizing mill downtime during scheduled maintenance.

Precision Performance

P6 accuracy grade ensures consistent roll gap control, directly impacting steel product thickness tolerance. Precise raceway geometry maintains stable rotation even under varying load conditions.

Application Scenarios

Work Roll Necks in Hot Strip Mills

The bearing supports high-speed rotation while managing direct heat transfer from steel slabs. Maintains precise roll positioning despite thermal expansion, ensuring consistent gauge control across the steel strip width.

Roughing Stands in Bar and Wire Mills

Handles severe impact loading as billets enter the rolls. Four-row construction provides radial stiffness to prevent roll deflection that would cause product defects or equipment damage.

Backup Rolls in Plate Mills

Hot Rolling Mill Bearings FC3045120 operates in heavily contaminated environments with mill scale and cooling water present. Sealed housing configurations with oil-mist lubrication systems protect against particulate ingress.

Material and Manufacturing Quality

Our heading utilize vacuum-degassed GCr15 bearing steel, heat-treated to accomplish surface hardness of HRC 58-62 whereas keeping up center durability for stun retention. The fabricating handle incorporates exactness crushing innovation and dimensional confirmation to guarantee reliable quality.

Each bearing experiences comprehensive testing counting vibration examination, stack rating confirmation, and dimensional assessment. Our three-level quality control framework keeps up over 99.9% capability rate for wrapped up products.

Installation and Maintenance Guidelines

Mount internal rings utilizing acceptance warming to accomplish legitimate impedances fit without scoring the roll neck. External ring congregations ought to be pre-positioned in chock lodgings with suitable outspread inner clearance.

Oil-air or oil-mist oil frameworks give ideal execution for high-speed applications. These frameworks offer nonstop cooling, decreased contact, and positive weight to prohibit contamination.

Regular checking through vibration examination and temperature sensors empowers prescient support planning. Supplant heading some time recently coming to benefit life limits to avoid disastrous failures.
