Miniature bearings are typically characterized by their compact dimensions, high rotational accuracy, and ability to operate under demanding speed and load conditions. With advanced manufacturing technology and strict quality control procedures, our bearings provide long service life and excellent running stability.

What Are Deep Groove Ball Bearings?

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

The NPBS bearing catalogue lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalogue offering, the NPBS Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.

6000 Series - Extra Light Ball Bearings

Metric miniature bearings with bore diameters ranging from 1.5 mm to 8 mm. The metric MR Series bearings are designed to withstand moderate radial and thrust loads, but only at low torques. It is an ideal bearing for small envelopes requiring high precision. Options include: ABEC classes (1-9), chrome steel and stainless steel construction, and open, metal shields or rubber seals.

6900 Series Deep Groove Radial Ball Bearings

Deep groove, thin section bearings are well suited for applications that have space and weight limitations. We carry thirty different 6900 series bearings with varying dimensions and loading limitations, from a dynamic load limit of 1,950 N to 159,000 N. Its bore diameter is 10 mm to 240 mm. Both metal shields (ZZ) and rubber seals (2RS) can be added to 6900 series bearings. For resistance to dust and moderate temperatures without affecting the speed rating, metal shields are effective. For protection from contamination and leakage, rubber seals are appropriate.
