1301 EM Bearing Structural Features & Performance Benefits
Double Row Design: Provides superior radial load capacity and stiffness compared to single row bearings, making it suitable for applications with significant radial forces.
Brass Cage Construction: The brass cage ensures excellent dimensional stability and guidance at high speeds, contributing to the bearing's limiting speed of 28,000 rpm.
Precision Manufacturing: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.008mm to 0) for precise fit and smooth operation in precision applications.
Optimized Lubrication: Comes pre-lubricated and operates effectively within a wide temperature range of -30° to 110°C, ensuring reliable performance across various operating conditions.
