1210 EKTN9 Bearing Product Overview & Core Advantages
The 1210 EKTN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads—both radial and axial—simultaneously. Its compact bearing dimensions (50mm bore, 90mm OD, 20mm width) and robust construction make it ideal for space-constrained, high-performance mechanical systems. The bearing delivers high rigidity and stable operation, supported by a nylon cage that contributes to its high-speed capabilities.

1210 EKTN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior stiffness and enables the bearing to support substantial radial dynamic loads (5962 lbf) and static loads (2059 lbf), making it suitable for applications with combined loading conditions.
High-Speed Performance: The TN9 nylon cage ensures smooth operation at elevated speeds, contributing to a limiting speed of 10,000 rpm. The cage material reduces weight and friction, enhancing the bearing's high-speed suitability.
Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and dimensional stability. The tight dimensional tolerances ensure precise fit and reliable performance in precision applications.
Maintenance & Environmental Compliance: The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C. It is compliant with ROHS and REACH standards, ensuring environmental safety.
