9.525 mm 158.75 mm 139.7 mm PRC055 Frequently Asked Questions about PRC055 PR Radial Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The precise manufacturing of the PRS Bearings PRC055 results in stable, predictable vibration baselines. This makes it highly compatible with modern IoT condition monitoring sensors for early fault detection.
The PRC055 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
Thanks to its robust 5,667 dynamic load capacity, the PRS Bearings PRC055 is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
The PRS Bearings PRC055 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PR Radial Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 139.7 mm bore interface.
