RB22025 Crossed Roller Bearing
The RB22025 Crossed Roller Bearing is a precision-engineered bearing designed for applications that require high rotational accuracy and compact structure. This model features a separable outer ring and an integral inner ring, making it ideal for limited installation spaces where rigidity and load-carrying capacity are essential.
Constructed with orthogonally arranged cylindrical rollers, the RB22025 bearing can support loads in all directions-radial, axial, and moment-within a single compact unit. This unique cross-roller design ensures smooth rotation, minimal deformation under load, and exceptional running accuracy.
01
Compact and Lightweight Design
The inner ring is a single piece, providing enhanced mounting precision and compact structure.
02

RB22025 Crossed Roller Bearing – FAQ
Can the RB22025 bearing be customized?
+
-
Yes. Cage materials, preload levels, and surface coatings can be customized according to specific operating environments and precision requirements.
How should the bearing be stored before installation?
+
-
Keep it in its original sealed package, stored in a dry and dust-free area at room temperature. Avoid exposure to moisture or strong vibrations.
Are there special materials or coatings available for harsh environments?
+
-
Yes. The RB22025 can be customized with stainless steel materials, nickel plating, or anti-corrosion coatings for use in humid, vacuum, or cleanroom conditions.
How can I verify the preload and alignment during installation?
+
-
Use a torque wrench or dial gauge to ensure uniform preload. Misalignment should be minimized to prevent uneven roller contact, which may affect accuracy or bearing life.
Can I replace the RB22025 with another model of the same series?
+
-
Yes, but check inner and outer diameter tolerances and width compatibility before replacement. Each model within the RB series has unique dimensional and load characteristics.
