Types of Bearing

The single row radial deep groove ball bearing is NMB's most widely produced ball bearing. In addition to open radial ball bearings, NMB also offers bearings with shields or seals. Shielded or sealed bearings provide a protective boundary from excess grease and other efficiency-compromising substances. Snap ring and flange type bearings provide improved housing fits. NMB also makes available, ultra thin type radial ball bearings.

Radial deep groove ball bearings

Radial deep groove ball bearings (R-, L-, RI-)

Characteristics :
The radial deep groove ball bearing is a very popular bearing. It is able to carry both radial and axial forces.

Types :
Open, shield, and seal types
Metric and inch series

Flanged radial deep groove ball bearings

Flanged radial deep groove ball bearings
(RF-, LF-, RIF-)

Characteristics :
The flanged radial deep groove ball bearing is a radial ball bearing with a flange featured on one side of the outer ring surfaceThe flange makes the axis direction for housing assembly easier to discern.

Types :
Open, shield, and seal types
Metric and inch series
* Stainless steel is the standard material.

Radial deep groove ball bearings with a snap ring on the outer ring

Radial deep groove ball bearings with a snap ring on the outer ring (RNR-, LNR-)

Characteristics :
. A radial deep groove ball bearing with a snap ring on the outer ring is comprised of an outside containing ring on a face of the outer ring surface, which makes axis orientation more identifiable and construction less time consuming.

Types :
Open and shield types
* High carbon chromium steel is the standard material.

Ultra thin radial ball bearings

Ultra thin radial ball bearings (A-)

Characteristics :
The bore to outer diameter ratio in ultra thin radial ball bearings exceeds that of standard radial ball bearings.

Types :
Open and shield types
* Stainless steel is the standard material.
