NTN - EPB4-307 | Heavy Duty Bearing | 87.31 × 190.50 × 120.70 × 349.30 mm

Details

NTN EPB4-307 is a HEAVY DUTY BEARING with inner diameter 87.31 mm, outer diameter 190.50 mm, width 120.70 mm and length 349.30 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage YES and lubrication STANDARD.

The NTN EPB2 bearing is a high-performance, heavy-duty Type E two-bolt cast iron pillow block unit, specifically engineered for extreme industrial applications requiring superior load management, durability, and resilience to misalignment and contaminants. The bearing insert utilizes spherical rolling elements arranged in double rows. The contact surface of rollers is a line contact, enabling them to support significantly higher radial and axial loads than ball bearings. The self-aligning capability accommodates static and dynamic angular misalignment of up to ±2° without compromising performance or service life. A superior double-lip sealing construction is used, comprising an oil-resistant synthetic rubber seal and a metal flinger (slinger). This design creates a long path for contaminants and utilizes excess grease as an additional barrier, providing reliable protection in extreme environments. Features are : Self-Aligning Internal Bearing, Reduced Maintenance Costs, Superior Shock and Vibration Resistance. Applications : Conveyor systems, Mining and construction machinery, Pumps and gearboxes, Agricultural equipment, Steel & Metals Industry.
