- Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.
- The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).
- Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation.
- Longer Life
Adopted NACHI original seal design to prevent contamination and grease leakage.
Contains special grease for wider temperature ranges and longer life. - Smooth and Quiet Operation
The precision level of our bearing components has been enhanced to ensure smooth and quiet operation. - Low Torque
Lower rotating torque by improving seal lips.
Standerd Configuration of Single-row, Deep-groove Ball Bearings
| Configuration | Design | Cross section | |
|---|---|---|---|
| Sealed or shielded Bearings | Open (no seals, no shields) |
Consists of inner and outer rings, balls, and cage. |  |
| Shield | One or two steel shields provide labyrinth clearance |  |
|
| Non-contact Rubber Seal | One or two non-contact rubber seals provide labyrinth clearance |  |
|
| Contact Rubber Seal | One or two contact rubber seals in contact with inner ring |  |
|
| Snap-ring Groove in Outer Ring | N: with snap-ring groove in outer ring. NR: with groove and snap ring in outer ring. (Use of snap ring allows easy mounting and simplified housing design.) Bearings may also be sealed or shielded. |  |
|
| Flanged Outer Ring | Wiith flanged outer ring. Applicable to Extra-small and Miniature bearings. Bearings may also be sealed or shielded. |  |
