RB30035 RB Series Cross Roller Bearing Manufacture for Industrial Robot Arm Rotary Table Slewing Ring

RB30035 RB Series Cross Roller Bearing Manufacture for Industrial Robot Arm Rotary Table Slewing Ring

• Precision Core for Robotic Joints: The RB30035 is a high-precision crossed roller bearing with a 300mm inner diameter, 395mm outer diameter, and 35mm width. Its 90° V-groove raceway and orthogonally crossed rollers achieve line contact, enabling simultaneous support of radial, axial, and tilting moment loads with minimal runout, critical for industrial robot arm rotary tables and slewing rings.
• Split Outer Ring for Easy Installation: Featuring a split outer ring and solid inner ring, this bearing allows straightforward mounting onto shafts or housings without disturbing the roller cage. The separable design simplifies assembly, reduces installation time, and ensures precise alignment for consistent rotational accuracy in demanding robotic applications.
• High Rigidity & Multi-Directional Load Support: Utilizing crossed cylindrical rollers with spacer retainers, the RB30035 provides 3–4× higher stiffness than conventional bearings. It supports heavy radial forces, bi-directional axial loads, and overturning moments simultaneously, minimizing deflection during dynamic robotic movements and ensuring stable, precise positioning.
• Durable GCr15 Steel Construction: Manufactured from high-carbon chromium steel (GCr15), this bearing offers superior hardness (60–64 HRC), excellent wear resistance, and high contact fatigue strength. This ensures long service life even in harsh industrial environments, making it a reliable solution for heavy-duty robotic automation and precision rotary systems.
• Versatile Industrial Applications: Engineered for space-constrained, high-load environments, the RB30035 is widely used in industrial robot joints, CNC machining center rotary tables, precision indexing platforms, and automated assembly equipment. Its compact design, high rigidity, and precision grades make it ideal for applications requiring smooth, backlash-free motion and exact angular control.
