MGK 608 ZZ is a single-row deep groove ball bearing.
Deep groove ball bearings have deep raceways and are primarily designed to accommodate radial loads. Their geometry also allows them to accommodate axial loads in both directions within the operating limits of the bearing design.
The compact dimensions of the 608 bearing make it suitable for many small rotating mechanisms.
The suffix:
ZZ
indicates metal shields on both sides of the bearing.
The alternative designation:
2Z
is also commonly used for a similar double-shielded configuration.
The metal shields help to:
limit the ingress of dust and small contaminants
protect the raceways and rolling elements
retain lubricant inside the bearing
protect internal bearing components without using contact rubber seals
The:
608 ZZ
and:
608 2RS
bearings have the same principal dimensions:
8x22x7 mm
However, they differ in their closure design.
Uses metal shields on both sides.
Uses elastomer seals on both sides.
The closure type affects contamination protection, friction and operating characteristics. A replacement should therefore not be selected solely by matching dimensions.
The designation:
608 ZZ MGK
should not automatically be supplemented with:
C3
The:
608 ZZ C3 MGK
is available as a separate variant with greater-than-normal internal clearance.
Therefore:
608 ZZ MGK
and:
608 ZZ C3 MGK
are not technically identical versions.
If C3 is not specified on the bearing, packaging or product documentation, increased C3 clearance should not be assumed.
Available product data for the 608 ZZ MGK indicates a:
steel cage
guided by the rolling elements.
The bearing rings and rolling elements are made from bearing steel.
The 608 bearing size is widely used in compact rotating mechanisms.
Typical applications for this bearing size may include:
small electric motors
fans
rollers
power tools
compact drive mechanisms
technical equipment
light mechanical assemblies
skate wheels
skateboard wheels
selected scooter wheels
Suitability for a specific machine or device should always be determined according to the technical requirements of the bearing arrangement.

Before selecting an alternative, verify:
608 bearing designation.
Bore diameter 8 mm.
Outside diameter 22 mm.
Width 7 mm.
Metal shields on both sides.
Required internal clearance.
Cage construction.
Required load capacity.
Operating speed.
Environmental conditions.
Matching the 8x22x7 mm dimensions alone is not sufficient to confirm full interchangeability.
The bearing has dimensions of 8x22x7 mm: 8 mm bore diameter, 22 mm outside diameter and 7 mm width.
It is a single-row deep groove ball bearing.
ZZ indicates metal shields on both sides of the bearing.
Yes. Both designations are commonly used for bearings with metal shields on both sides, although exact suffix terminology can vary between manufacturers.
C3 should not be assumed. The 608 ZZ MGK version is specified with normal internal clearance. 608 ZZ C3 MGK is a separate version with increased internal clearance.
Available product data indicates a steel cage guided by the rolling elements.
Yes. Standard 608 ZZ and 608 2RS bearings have dimensions of 8x22x7 mm, but they differ in their closure design.
The 608 bearing size is widely used in skate and skateboard wheels. Suitability of a specific bearing should still be checked against the required clearance, closure type, load, speed and operating conditions.
No. Bearings with identical dimensions may differ in closure type, internal clearance, cage design, precision and other technical characteristics.
608 ZZ MGK is a single-row deep groove ball bearing with dimensions 8x22x7 mm and metal shields on both sides. Available product data indicates a steel cage, cylindrical 8 mm bore and normal internal clearance. The 608 ZZ C3 MGK version with greater-than-normal internal clearance is a separate bearing variant.
