Collection: Metric deep groove ball bearings

Metric deep groove ball bearings are manufactured to ISO dimensions and are typically produced in 5mm increments such as 20mm, 25mm, 30mm etc. Smaller and larger metric bearings will have larger intervals between the availability but all of the dimensions will be produced to an exact metric dimension. This helps machinery manufacturers and design engineers who can pick up a bearing catalogue from any manufacturer and design their application with the knowledge that their purchasing team will not be constrained to one particular manufacturer. 

Metric deep groove ball bearings are the most popular type of bearing used worldwide today. Skateboard bearings, typically using a 608-ZZ are a metric bearing. Mountain bikes commonly use a 6902-2RS metric bearing, clutch applications commonly use a 6203-ZZC3 metric bearing.

Metric deep groove ball bearings are available in stainless steel, available with different cage designs and different grease and internal clearance combinations. This makes them extremely versatile and suitable for a wide range of applications.

Interested in learning more about deep groove ball bearings ?

We have information on different designs for deep groove ball bearings including, single row deep groove ball bearings including bearings with snap rings or snap ring grooves and double row deep groove ball bearings as well as on stainless steel deep groove ball bearings which can be suitable for use in corrosive environments.

All of our ball bearings are available either as open types where the balls are exposed, sealed types where the bearings are greased for life and then seals are inserted to prevent contaminants getting in and the grease getting out and as shielded bearings where the grease is retained and some sealing protection is offered. Our deep groove ball bearings are also available with different internal clearances designed to improve performance in certain applications. We can supply deep groove ball bearings in both metric and inch sized bearings and with a range of internal clearances which can be utilised to either help reduce noise and vibrations by selecting a lower clearance bearing such as C2 bearing clearance or more standard clearances which cover most applications such as CN bearing clearance or C3 bearing clearance or applications which maybe require greater clearances such as high temperature applications may use one of either C4 bearing clearance, C5 bearing clearance, C5L bearing clearance, C5H bearing clearance so it doesn't matter which you have, the same clearance principles will follow.

If you have space constraints but need a bearing to take more load than a standard deep groove ball bearing then we have max load bearings with filling slots and we also have lots of useful information on deep groove ball bearings that have been designed for specific applications or with special uses in mind like, low noise bearings, bearings for the food industry and energy efficient bearings which are becoming increasingly necessary and popular due to rising energy costs and the need to protect the environment.
