Extended inner rings provide additional design flexibility. Sizes from 0.0400" inner diameter to 0.8750" outer diameter are available. Like the other DDRI series bearings, they provide high performance and precision for small applications, and are best suited for moderate radial and thrust loads at low levels of torque. Available in chrome and stainless steel, Abec classes 1-9.
