The 6201 bearing is typically composed of an inner ring, outer ring, ball elements, and a cage. The groove in the raceway is slightly larger than the radius of the steel balls. Due to the point contact between the balls and the raceway, the 6201 bearing can withstand both axial loads in both directions and radial loads. It is commonly used in pairs under normal conditions to minimize the internal axial forces caused by the load and to primarily handle radial loads.
Acting as the stationary raceway, the outer ring completes the race circuit and encapsulates the entire bearing.
These small, spherical elements provide the necessary separation and facilitate smooth rotation.

6205 Bearing Dimensions:Your Ultimate Guide to Sizing
The 6201 deep groove ball bearing has a 12 mm bore (inner diameter), 32 mm outer diameter and 10 mm width, weighs about 37 g, and has a dynamic load rating of 535 kgf and static load rating of 305 kgf. These are ISO-standard dimensions suitable for direct replacement. Final selection should still be confirmed against your shaft size, mounting space and load conditions.
In the 6201 bearing designation, "6" indicates a single-row deep groove ball bearing, "2" the light series, and "01" a 12 mm bore. Suffixes indicate the closure type: Z or 2Z for metal shields (single/double side), R or 2R for rubber seals (single/double side). Reading the code correctly helps you match the right spec when replacing or requesting a quote.
The 6201 bearing comes in three main closures: ZZ (metal shield), 2RS (rubber seal) and OPEN. ZZ blocks dust and retains grease, suiting general medium-to-high precision applications; 2RS offers better water and dust resistance for harsh environments; OPEN has no closure, suiting clean settings or those needing regular cleaning and relubrication. Choose based on environment, precision/speed and maintenance needs.
The main differences between the 6201 and 6202 are outer diameter, width and load capacity. The 6201 has a 12 mm bore, 32 mm OD and 10 mm width; the 6202 has a 15 mm bore, 35 mm OD and 11 mm width, with higher load ratings. Start with your shaft diameter, then match mounting space and load. If you are unsure which fits your duty, share shaft size and load data for evaluation.
A noisy or rough-running 6201 bearing does not always mean the bearing itself has failed. In practice the root cause often lies in the press-fit condition, mounting concentricity, grease selection or contamination from the operating environment. Check the mounting and lubrication first before deciding to change the type. Share the running sound, mounting conditions and duty description, and we can help assess the cause.
If your 6201 bearing operates in damp, wet or dusty conditions, the 2RS rubber-sealed version is worth prioritising, as it offers better water and dust resistance than the ZZ metal shield. For more severe environments or specific corrosion concerns, material and grease pairing can also be evaluated. Share your operating environment and duty so we can help identify the most suitable seal and protection combination.
The service life of a 6201 bearing is mainly affected by load, speed, lubrication, mounting accuracy and operating environment. Excessive load, insufficient lubrication, misalignment or contamination all accelerate wear. Selecting the right closure and grease and ensuring correct mounting help maintain stable operation. To evaluate a suitable spec for a specific duty, share your load, speed and environment conditions.
The MOQ for 6201 bearings depends on the closure type, grease specification and whether customization is required. Standard items and integrated custom work have different terms. Share the model, closure type, quantity and delivery timing, and we can propose a suitable supply and quotation plan. For ongoing demand, stable stocking arrangements can also be discussed.
To request a 6201 bearing quote or sample, provide the model (including closure type, e.g. 6201ZZ or 6201-2RS), quantity, application and delivery timing. If you have special lubrication, precision or protection requirements, note those too. The more complete the information, the faster we can identify a suitable spec and provide an accurate quote with fewer back-and-forth exchanges.
When a 6201 bearing needs rubber overmolding, secondary machining or surface treatment, ISK Bearings can integrate bearing manufacturing and machining under a single coordination flow, so procurement does not have to manage several suppliers separately. This reduces the hidden costs of inter-plant shipping, scheduling waits and spec confirmation. Share your drawing, machining needs and quantity to evaluate an integrated supply plan.
