Product Description

NMB DDRI-814ZZMTRA5P24LY121 is a single row shielded deep groove ball bearing engineered for high precision and reliable performance in demanding mechanical and fluid power applications. With an inside diameter of 6.35 mm and an outside diameter of 12.7 mm, this bearing is well-suited for integration in precision instruments, chart recorders, and similar assemblies where accuracy and stability are paramount.

Built with a steel cage, martensitic stainless steel race, and stainless steel balls, the bearing offers robust corrosion resistance, minimizing wear and extending operational life. The shielded end type provides debris protection, maintaining cleanliness and reducing the need for maintenance in challenging environments.

The race width of 4.77 mm makes this bearing ideal for compact installation scenarios. Static load rating stands at 374 kN while dynamic load rating is 828 N, supporting demanding mechanical loads and rotational operations. Parallel bore and plain race type ensure consistent fit and operation within rotary housing units.

Manufactured to ABEC 5 (American Bearing Engineers Committee) precision standards, this bearing guarantees reliable accuracy and performance suitable for industrial and laboratory contexts. The internal clearance type is CN, accommodating standard axial and radial movements.

Suitable for rotary bearings and housing units in industrial machinery, laboratory equipment, manufacturing lines, and commercial HVAC systems, the double row deep groove configuration delivers excellent stability and smooth rotation. The shielded bearing design is preferred for installations requiring protection against contaminants and enhanced bearing life.

Applications include industrial instrumentation, fluid power assemblies, chart recording machines, laboratory devices, and precision rotary mechanisms. Its construction ensures compatibility with both metric and imperial bearing mounts.
