B: 2.3 mm
Complete dimensional specification:
2x5x2.3 mm
Its extremely small dimensions make 682ZZ suitable for compact precision mechanisms where available installation space is very limited.
682 - miniature deep groove ball bearing size with dimensions 2x5x2.3 mm.
ZZ - metal shields on both sides of the bearing.
The complete 682ZZ designation is important when selecting a replacement because open, shielded and sealed versions can differ in their closure design.
EZO 682ZZ is a single-row deep groove ball bearing consisting of:
Its deep raceway geometry is primarily designed to accommodate radial loads. As a deep groove ball bearing, it can also accommodate axial loads within the operating limits of the specific bearing arrangement.
The ZZ designation identifies metal shields on both sides.
The shields help to:
ZZ metal shields should therefore be distinguished from elastomer seals.
The principal difference is the closure design.
682ZZ - metal shields on both sides.
682 - open bearing version.
The ZZ version provides additional protection for the bearing interior. Although the basic dimensions may be identical, the closure configuration should be considered when selecting a replacement.
For versions with the same basic dimensions:
682ZZ uses metal shields.
682-2RS uses seals on both sides.
These closure systems provide different operating characteristics, so ZZ and 2RS versions should not automatically be considered technically identical.
With a 2 mm bore, an outside diameter of only 5 mm and a width of 2.3 mm, EZO 682ZZ is an extremely compact bearing.
Its miniature dimensions allow it to be incorporated into small precision mechanisms where conventional bearing sizes would require too much installation space.
Before selecting EZO 682ZZ, verify:
With miniature bearings, even a small dimensional difference can prevent correct installation.
Due to its miniature dimensions, EZO 682ZZ should be handled carefully during installation.
When fitting the bearing onto a shaft, mounting force should be applied to the inner ring. When pressing it into a housing, force should be applied to the outer ring.
Mounting force should not be transmitted through the balls, and direct pressure on the ZZ metal shields should be avoided.
The bearing measures 2x5x2.3 mm, with a 2 mm bore, 5 mm outside diameter and 2.3 mm width.
It is a miniature single-row deep groove ball bearing.
ZZ indicates metal shields on both sides of the bearing.
Yes. Its basic dimensions are specified in the metric system.
682ZZ has metal shields on both sides, while the basic 682 version is open.
682ZZ uses metal shields, while 682-2RS uses seals on both sides.
No. The 2.3 mm width, closure configuration and other technical requirements must also be verified.
EZO 682ZZ 2x5x2.3 mm is a miniature single-row deep groove ball bearing with a 2 mm bore, 5 mm outside diameter and 2.3 mm width. The ZZ version features metal shields on both sides, helping protect the bearing interior against contaminants and retain lubricant.
