6210 deep groove ball bearing is part of CXJSD’s 6200 series, with a 50 mm bore, 90 mm outside diameter, and 20 mm width. According to CXJSD’s specifications, the 6210 has a minimum chamfer of 1.1 mm, a basic dynamic load rating of 35.0 kN, a basic static load rating of 23.2 kN, and uses 10 balls with a ball diameter of 12.7 mm. Its reference speed is 7,100 r/min with grease lubrication and 8,300 r/min with oil lubrication, with a listed weight of approximately 0.454 kg per piece. The 6210 is available within the 6200 series in open, ZZ, 2RZ, and 2RS configurations.

The 6210 is built around inner and outer raceways, steel balls, a cage and selectable sealing configurations.
_1789961202_WNo_418d418.jpg)
The inner ring has a 50 mm bore and provides the raceway that supports the rolling elements while mounting onto the shaft.
The outer ring has an 90 mm outside diameter and contains the outer raceway for guiding the balls during rotation.
The 6210 uses 10 balls with a 12.7 mm diameter, which roll between the inner and outer raceways to reduce sliding friction.
The cage separates and guides the balls so they remain properly spaced as the bearing rotates.
The deep-groove raceways are designed to accommodate radial loads and moderate axial loads in both directions, which is a characteristic of single-row deep groove ball bearings.
The 6210 is available in open, ZZ, 2RZ, and 2RS configurations, allowing the bearing to be selected according to lubrication and protection requirements.
The 6210 deep groove ball bearing is suitable for rotating equipment where its 50 mm bore, 90 mm outside diameter, 20 mm width, load ratings, and reference speeds meet the application requirements.
The 6210 can support rotating shafts in electric motors and fans, where its deep groove design accommodates radial loads and moderate axial loads.
In industrial machinery, the 6210 provides shaft support for rotating components when the bearing dimensions, load ratings, speed, and mounting conditions are suitable.
The 6210 can be used to support rotating shafts in pumps and related fluid-handling equipment when its operating specifications match the equipment requirements.
For conveyors and material-handling equipment, the 6210 can support rotating shafts and components where its 50 mm bore and 20 mm width provide the required fit.
The 6210 can be applied to rotating components in agricultural machinery when its dimensions, load capacity, lubrication, and operating speed are appropriate for the equipment.
Common buyer feedback and purchasing considerations for the 6210 deep groove ball bearing, presented as illustrative examples rather than verified customer reviews.
The first thing I checked was the size. The 50 × 90 × 20 mm dimensions are pretty straightforward, so it was easy to compare with the bearing we were replacing. For maintenance work, having the basic dimensions clearly listed saves a lot of time.
What I like about the 6210 is that the key numbers are easy to check before ordering. The 35.0 kN dynamic load rating and 23.2 kN static load rating give us a useful starting point when checking whether the bearing fits the motor application.
I usually pay close attention to the speed rating because the bearing will be running for long periods. Seeing 7,100 r/min with grease and 8,300 r/min with oil makes it much easier to compare the 6210 with other options for the same equipment.
For me, the weight and basic construction details are also useful when planning stock. The 6210 is listed at about 0.454 kg per piece, and the 10 balls with a 12.7 mm diameter give a clear picture of the bearing configuration.
I prefer checking the complete specification before sending an inquiry. With the 6210, the bore, outside diameter, width, load ratings and lubrication speeds are all useful details, so I can prepare the purchasing requirements without going back and forth too much.

Common technical questions and key specifications to check before selecting a 6210 deep groove ball bearing.
A standard 6210 deep groove ball bearing measures 50 mm bore × 90 mm outside diameter × 20 mm width. Check all three dimensions against the shaft and housing before ordering, because the bearing number alone should not replace a physical fit check.

The CXJSD 6210 has a 35.0 kN basic dynamic load rating and a 23.2 kN basic static load rating. These values help engineers compare load capacity, but the actual bearing selection also depends on speed, load direction, lubrication, mounting and operating conditions.

The basic 6210 is the open version, while 2RS uses rubber contact seals on both sides and ZZ/2Z uses metal shields; choose the configuration according to contamination, moisture, lubrication and required running speed.
_1789960287_WNo_900d429.jpg)
Common causes include contamination, incorrect mounting, excessive or insufficient lubrication, improper shaft or housing fits, misalignment, excessive load and bearing damage; checking installation, lubrication, shaft/housing condition and vibration together is more useful than replacing the bearing immediately.
