NMB Double Row Deep Groove Ball Bearing Flanged Shielded 6.35 mm ID, 15.87 mm OD, 4.97 mm Width DDRF-4HHRA5P24LY121

NMB DDRF-4HHRA5P24LY121 Double Row Deep Groove Ball Bearing features a flanged and shielded design, providing reliable and precise rotational performance. With an inside diameter of 6.35 mm, outside diameter of 15.87 mm, and a race width of 4.97 mm, this bearing offers a compact form factor ideal for precision applications.

The bearing races are made from martensitic stainless steel, offering excellent corrosion resistance and mechanical strength. Stainless steel balls ensure durability and smooth operation, while the steel cage maintains proper ball spacing to minimize friction and wear.

This bearing type is suitable for use in precision instruments, chart recorders, and other applications requiring reliable rotary motion. Its flanged construction aids in mounting accuracy and secure positioning within assemblies. The shielded end type helps prevent ingress of dust and other contaminants, extending bearing life.

The internal clearance is classified as CN, ensuring a standard tolerance fit. Static load rating by NMB is 599 kN, indicating the bearing's capacity to withstand heavy axial and radial loads without deformation. The dynamic load rating is 1.47 kN, supporting smooth operation at varying speeds.

Manufactured in Thailand, this bearing complies with industry standards and is crafted to meet ABEC 5 precision requirements, ensuring consistent high performance. Constructed with martensitic stainless steel race for enhanced durability.
