KHP RRAR 2 1/2 P5 High Precision Mounted Unit Bearing Insert | 2.5 Inch Bore
The KHP RRAR 2 1/2 P5 bearing is engineered for demanding industrial environments where both reliability and exceptional precision are paramount. Featuring a 2 1/2 inch (63.5 mm) bore and an extended inner ring, this relubricatable radial ball bearing insert is designed to handle significant radial and axial loads typically encountered in heavy-duty conveyors, agricultural machinery, and processing equipment. Manufactured to the stringent P5 precision class (ISO Class 5), the RRAR 2 1/2 guarantees tighter running accuracy, reduced vibration, and superior dimensional stability compared to standard bearings, leading directly to increased equipment lifespan and less shaft deflection. The robust construction includes through-hardened steel races and is optimized for easy integration into standard housing units (e.g., pillow blocks or flange units).
Equipped with specialized triple-lip seals (RRR configuration), the KHP RRAR 2 1/2 P5 effectively locks out contaminants, moisture, and fine particulates, making it ideal for dusty or wet applications like quarrying and food processing wash-down areas. The relubrication capability, facilitated by a grease fitting access groove, allows for proactive maintenance and extending service intervals even under extreme operating conditions. Choosing the KHP P5-rated insert ensures maximized operational uptime, lower total cost of ownership, and performance stability even at moderately high rotational speeds where standard precision bearings might fail.
