DDRF-3

DDRF-3 Inch Size NMB Flanged Ball Bearings have deep groove geometry for high speeds and supporting both radial and axial loads. This DDRF-3 Inch Size NMB Flanged Ball Bearings are for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. For instance, DDRF-3 Inch Size NMB Flanged Ball Bearings are often used in motors, ATMs as well as Card Readers. In Food & Beverage Industry, DDRF-3 is also popular. More applications about DDRF-3 are as follows.

General Selection Factors

Several factors must be considered for choosing NMB bearings. These factors include the ring material, design, shields and seals, cage, Annual Bearing Engineering Committee (ABEC) grade, radial play, and lubricant. Miniature bearings are available in open, sealed and shielded configurations. Seals and shields are used in miniature bearings (specifically ball bearings) to retain lubricants and prevent particulate contamination from reaching critical surfaces. Seals are used where minimal light contact is offered. Seals for miniature bearings provide deterrence to particulate contamination, but increase torque and limit operating speeds. Shields are used in most applications.
