SKF 6206 bearing

When replacing bearings for motors, conveyor systems, or industrial machinery, choosing the correct bearing is important to ensure stable shaft rotation and minimize machine downtime. The SKF 6206 bearing is a widely used single-row deep groove ball bearing with dimensions of 30 × 62 × 16 mm. It is available in several versions, including 6206, 6206-2Z, 6206-2Z/C3, 6206-2RS1, 6206-2RS1/C3, and 6206-2RS1NR. Depending on the operating environment, speed, and sealing requirements, users can select the appropriate bearing version.

SKF 6206 Bearing Specifications

The SKF 6206 bearing belongs to the single-row deep groove ball bearing series. Its compact design makes it suitable for a wide range of rotating machinery and equipment. The main specifications of the SKF 6206 bearing are shown below:

The basic dimensions of the 6206 series are 30 × 62 × 16 mm. However, when ordering, users should not rely solely on the dimensions. The suffix following the 6206 designation should also be checked to identify the bearing's sealing arrangement, internal clearance, and configuration.

Types of SKF 6206 Bearings

The SKF 6206 bearing is available in several versions to meet different operating requirements. Common designations include:

SKF 6206 Bearing

SKF 6206 is an open bearing without shields or seals on either side. This open design is suitable for machine assemblies with a separate lubrication system or controlled operating environments.

With an open bearing, users can replenish oil or grease according to the equipment's lubrication requirements. When used in environments with high levels of dust, water, or contaminants, appropriate protection should be provided for the bearing assembly. Compared with the SKF 6205 bearing, the SKF 6206 has larger bore and outside diameters, so the bearing should be selected according to the shaft and housing dimensions of the equipment.

SKF 6206-2Z Bearing

The 6206-2Z is equipped with two metal shields on both sides. The shields help limit the entry of dust and retain the lubricant inside the bearing. This version is commonly selected for machine assemblies that require more protection than an open 6206 bearing but do not require the sealing level provided by rubber contact seals.

SKF 6206-2Z/C3 Bearing

The 6206-2Z/C3 has the same basic configuration as the 6206-2Z but features C3 radial internal clearance. C3 clearance is greater than standard internal clearance and may be selected for applications where operating temperature or the type of fit affects the internal clearance of the bearing. C3 should be selected based on actual operating conditions rather than being used as a default option for every application.

SKF 6206-2RS1 Bearing

The 6206-2RS1 uses two contact rubber seals on both sides and is pre-greased. Compared with the 2Z metal-shielded version, the rubber seals provide greater protection against dust and moisture entering from the outside. This version is commonly selected for machine assemblies that require increased sealing protection.

SKF 6206-2RS1/C3 Bearing

The 6206-2RS1/C3 combines 2RS1 rubber seals with C3 radial internal clearance. This designation is suitable when the equipment requires both rubber sealing and greater internal clearance than the standard specification. When replacing a bearing, the exact designation should be checked to ensure that the replacement is compatible with the machine design.

SKF 6206-2RS1NR Bearing

The SKF 6206-2RS1NR features 2RS1 rubber seals and an additional snap ring to secure the bearing in its designed mounting position. This version is suitable for assemblies that use a snap ring to retain the bearing. When ordering a replacement, the NR suffix should be checked if the existing bearing uses a snap ring.

Meaning of the SKF 6206 Bearing Designations

Understanding the suffixes following the 6206 designation helps users avoid ordering the wrong bearing.

Because these designations share the same basic dimensions but differ in construction, users should provide the complete bearing designation when requesting a quotation or replacement.

Applications of SKF 6206 Bearings

With its standard dimensions and deep groove ball bearing design, the SKF 6206 can be used in various types of machinery and equipment, including:

• Electric motors and generators.
• Conveyor drive assemblies.
• Rollers and rotating mechanisms in machinery.
• Pumps, fans, and mechanical equipment.
• Packaging machines, processing machinery, and production lines.
• Industrial rotating shaft assemblies requiring a compatible bearing.

The appropriate 6206 version should be selected based on the load, rotational speed, operating temperature, dust and moisture exposure, and mounting method of the equipment.

When Should You Choose 6206-2Z or 6206-2RS1?

These two versions have the same basic dimensions but differ in their sealing arrangements.

• 6206-2Z uses metal shields and is suitable for applications that prioritize smooth operation and do not require the higher sealing level provided by rubber contact seals.
• 6206-2RS1 uses contact rubber seals and is more suitable for environments where protection against dust and moisture ingress is required.

If the equipment is currently using a 6206-2Z, 6206-2RS1, or C3 version, the same designation should generally be used as the replacement, or technical advice should be obtained before switching to another version.

SKF 6206 Bearing Price

The price of an SKF 6206 bearing depends on the product designation, shield or seal configuration, internal clearance, order quantity, and supply conditions. Therefore, a single price should not be applied to all 6206 versions.

To receive an accurate quotation, customers can provide BELOTA with:

• The required bearing designation.
• Quantity.
• Photos of the existing bearing or product packaging.
• Machine information if the bearing designation has not been identified.
• Required delivery time.

Belota will check the product designation, advise on the appropriate version, and provide a quotation based on the actual requirements.
