Key Features of the 206KRRB
1-Inch Hex Bore
The 1-inch hex bore is the defining feature of the 206KRRB.
Designed for a compatible hex shaft, it provides positive mechanical engagement and supports torque transmission in agricultural equipment.
Key benefits include:
-
Positive shaft engagement
-
Reliable torque transmission
-
Compatibility with 1-inch hex shafts
-
Suitable for agricultural equipment designed around hex-shaft assemblies
Double-Sided Sealing
Agricultural machinery operates in environments where dust, soil, moisture, and plant residue can affect bearing performance.
The double-sided seal helps reduce contaminant entry and retain internal grease, supporting reliable operation in outdoor agricultural applications.
Actual sealing performance depends on operating conditions, shaft condition, installation, and contamination exposure.
Spherical Outer Ring
The spherical outer ring is designed for use with compatible agricultural bearing housings.
Its spherical surface allows a certain degree of housing alignment variation and is suitable for agricultural assemblies exposed to vibration and structural movement.
Housing dimensions and fit should be verified before replacement.
206KRRB Replacement & Compatibility
The 206KRRB agricultural bearing can be used as an OEM or aftermarket replacement when its bore configuration, dimensions, housing fit, sealing arrangement, and application requirements match the original bearing.
For agricultural equipment using a 1-inch hex shaft, verify the bearing-to-shaft interface and key mounting dimensions before ordering.

What to Check Before Replacement
Before replacing an existing agricultural bearing, confirm:
-
Bearing number or OEM reference
-
Hex shaft size and geometry
-
Outside diameter
-
Overall width
-
Inner-ring width
-
Housing dimensions
-
Seal configuration
-
Load and operating conditions
Matching the nominal bearing number alone does not guarantee interchangeability. The shaft, housing, dimensions, sealing arrangement, and operating conditions should also be compatible.
OEM Replacement Verification
For OEM and aftermarket replacement projects, provide any available information, such as:
-
Existing bearing number
-
Original manufacturer
-
Equipment model
-
Shaft size
-
Bearing dimensions
-
Product drawing
-
Product photo
-
Required quantity
Our technical team can review the available information and help evaluate whether the 206KRRB is a suitable replacement.
