Optimized for Heavy-Duty Rolling Mill Environments

This roller bearing performs best under heavy radial and axial loads typical in rolling mill applications. Its design accommodates the continuous operation and moderate vibration levels found in roller systems, with lubrication options (grease or oil) to suit specific operational conditions. The precision rating options (from P0 to P2) allow customization based on the required running accuracy, ensuring smooth performance even at high rotational speeds.

Wichtige technische Merkmale, die die Leistung beeinflussen

The 85*150*28 mm specification provides a balance of load capacity and compact design, critical for fitting within rolling mill equipment constraints. Precision ratings directly affect operational stability—higher grades like P5 or P4 reduce vibration (Z1V1 to Z3V3 options) and extend service life by minimizing internal clearance variations. The bearing’s construction supports both grease and oil lubrication, offering flexibility to adapt to maintenance schedules and operating temperatures. Vibration classes ensure compatibility with noise-sensitive environments, a crucial factor in reducing equipment wear and operator fatigue.
