The number printed on a bearing provides useful information, but it does not tell you everything you need to know before buying a replacement. Along with the bearing designation, check the 6202 bearing dimensions, sealing type, load ratings, speed, weight, and application requirements.

The 6202 bearing is a single-row deep groove ball bearing with a 15 mm bore, 35 mm outside diameter, and 11 mm width. These dimensions are standard for the 6202 series, but details such as load ratings, speed limits, seals, clearance, and weight can vary by manufacturer and variant. Checking the 6202 bearing specification helps ensure you select the right version for the equipment.

6202 Bearing Dimensions and Basic Specifications

The first thing to check when replacing a bearing is whether its physical dimensions match the shaft and housing. The standard 6202 bearing dimensions are 15 × 35 × 11 mm.

Specification	6202 Bearing
Bore diameter	15 mm
Outside diameter	35 mm
Width	11 mm
Bearing type	Single-row deep groove ball bearing
Approx. weight	45 g
Basic dynamic load rating	8,400 N
Basic static load rating	3,750 N

Load ratings shown here are from NSK’s standard 6202 specification. Other manufacturers or variants can have different ratings, so always check the manufacturer’s catalogue before making a technical selection.

The 6202 bearing size makes it suitable for compact rotating equipment where there is limited installation space. Its standard dimensions also make it easy to cross-reference with equivalent products from different bearing manufacturers.

What Does the 6202 Bearing Number Mean?

The designation gives useful information about the bearing. The 6202 belongs to the 62 series of deep groove ball bearings. The final two digits, “02,” indicate a 15 mm bore in this bearing series, which is an important part of the 6202 bearing size.

The number alone does not tell you whether the bearing is open, shielded, or sealed. Suffixes are important when ordering a replacement.

For example-

• 6202 – open bearing
• 6202-ZZ – metal shields
• 6202-2RS – rubber seals on both sides

The exact suffix system can vary between manufacturers, so it is better to check the brand’s catalogue rather than assume that every suffix means exactly the same thing.

6202 Bearing Weight and Load Capacity

The 6202 bearing weight is approximately 45 grams according to NSK’s standard open 6202 specification. ISK also lists 45 g for its standard 6202 bearing.

Weight is useful when estimating component mass, but it should not be the main factor when selecting a bearing. Load ratings are much more important for determining whether a bearing can handle the forces in a particular machine.

For example, NSK lists a basic dynamic load rating of 8,400 N and a basic static load rating of 3,750 N for its standard 6202 bearing. These values form part of the 6202 bearing specification and can help when comparing the bearing with the machine’s load requirements.

These figures should not be treated as universal values for every 6202 bearing. Brand, internal clearance, material, precision class, and design can change the specification.

6202 Bearing Speed and Sealing Options

The sealing arrangement can affect how a 6202 bearing performs. A 6202-2RS uses rubber seals to help protect the internal components from dust, moisture, and other contaminants. LILY describes the 6202RS as a single-row deep groove ball bearing with rubber sealing and notes that the seal provides protection in applications where contamination is a concern.

A 6202-ZZ uses metal shields. These generally create less sealing friction than contact rubber seals, which can make them useful where speed is more important and contamination is relatively controlled.

Speed ratings also vary by manufacturer and configuration. For example, NSK lists 22,000 rpm with grease and 28,000 rpm with oil for its standard open 6202 bearing. ISK lists different limits for open, ZZ/2RS, and DU/DDU variants. For this reason, do not use one generic RPM figure for every 6202 bearing.

Where Is the 6202 Bearing Used?

The compact design of the 6202 makes it suitable for many rotating applications. Common uses include the following.

• Electric motors
• Pumps
• Fans
• Household appliances
• Automotive components
• Power tools
• Industrial machinery

LILY specifically lists electric motors, automotive components, industrial machinery, household appliances, and power tools among applications for the 6202RS.

The exact application should determine the bearing variant. A sealed 6202-2RS may be more suitable where protection from dust or moisture is needed, while an open or shielded version may be preferred for other operating conditions.

How to Choose the Right 6202 Bearing

Matching the 6202 bearing specification to the machine requires more than checking 15 × 35 × 11 mm. Before ordering, check the following.

1. Confirm the dimensions: The shaft must accept the 15 mm bore, while the housing must accommodate the 35 mm outside diameter and 11 mm width.

2. Check the seal or shield: Choose open, shielded, or sealed construction according to contamination, lubrication, and speed requirements.

3. Check load requirements: Compare the manufacturer’s dynamic and static load ratings with the actual machine loads.

4. Check operating speed: Use the manufacturer’s speed data for the exact bearing variant.

5. Check clearance and precision: Applications with higher temperatures, specific fits, or tighter running requirements may need a particular internal clearance or precision class.

Conclusion

The 6202 bearing dimensions of 15 × 35 × 11 mm make this a common and versatile bearing size. However, the correct replacement depends on more than dimensions. Check the 6202 bearing size, weight, specification, seal type, load rating, speed, and operating conditions before placing an order.
