NTN 620500 Deep Groove Radial Ball Bearing – Single-Sealed Design for High-Speed, Contaminant-Resistant Applications
The NTN 620500 is a deep groove radial ball bearing with a 52mm outer diameter and single seal, engineered to provide smooth rotation, low-friction performance, and basic protection against dust and debris. Ideal for use in electric motors, industrial pumps, small gearboxes, and automated equipment, this bearing balances load capacity and speed capability.
Constructed from high-quality NTN bearing steel, the 620500 features precision-ground raceways and hardened steel balls for consistent performance under both radial and axial loads. The one-sided seal (typically rubber or metal) protects the bearing interior while allowing for open lubrication on the unsealed side when needed.
This configuration is perfect for systems requiring partial protection with access to internal lubrication or ventilation on one side.
Choose the NTN 620500 Ball Bearing for versatile installation, durable sealing, and proven NTN performance in semi-enclosed bearing applications.
