FAQS

QWhat is a single row deep groove ball bearing?

ASingle-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery.

QWhat is a double row bearing?

ADouble Row. Two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard.

QWhat is a double row angular contact bearing?

ADouble row bearings are angular contact designed to meet the demand of increased axial and radial load where the application design limits the operating space. Being slightly wider than the 6200 and 6300 series, double row bearings are capable of loads where the single row bearing is inadequate.

QWhat are angular contact bearings?

AAn angular contact bearing is a type of specialty ball bearing used in many manufacturing and industrial applications. This relatively small device is designed to support a greater range of forces than a standard bearing, and to work within even the most precisely engineered machines and equipment.
