SX crossed roller bearing

Design Principles: The 90° orthogonal crossed arrangement of rollers optimizes the length and distribution of contact lines, forming a symmetrical "X"-shaped load-bearing structure that evenly distributes radial, axial, and moment high loads to each roller, avoiding local stress overload under high loads and improving bearing stability. The split inner and outer ring design allows precise control of preload by adding or removing adjustment shims, adapting to different load requirements; the precision shoulder structure enhances installation positioning accuracy, ensuring coaxiality and rotational stability under high loads. Performance Features: Core Advantage of High Load Capacity: Optimized contact design between rollers and raceways, axial bearing capacity up to 560 KN, radial bearing capacity up to 395 KN, increased by more than 50% compared with conventional crossed roller bearings. Precise Preload Adjustment: Split structure supports refined preload settings, effectively improving bearing rigidity and rotational accuracy, adapting to precision positioning requirements under high loads. High Rigidity & Deformation Resistance: Crossed roller layout + high-load reinforced material, deformation resistance increased by more than 4 times, ensuring rotational accuracy and stability under high-load working conditions. Long Service Life & Wear Resistance: GCr15 material with high-load reinforced treatment, precision polishing of roller end faces (Ra≤0.08μm), fatigue life and wear resistance increased by 40%. Customization Options: Supports non-standard size customization, shoulder specification (DE/DI) customization, high-load optimization design, corrosion-resistant material (SUS440C), special lubrication solutions for ultra-high/low temperature, and greasing hole position customization.

Working Principle Roller Arrangement and Load Distribution: The rollers are arranged in a 90° orthogonal cross pattern, forming an optimized "X" contact line. This increases the contact area while evenly distributing high radial, axial, and moment loads, preventing localized stress overload. Under high load conditions, the symmetrically distributed contact lines effectively balance load stress, improving load-bearing stability. Moment loads are efficiently transmitted through the diagonal rollers, further enhancing high-load bearing efficiency and structural rigidity. Lubrication and Sealing: - Sealing Protection: Double-contact seals (UU/U) effectively prevent dust, liquids, and impurities from entering, suitable for complex high-load environments; the open design meets the lubrication requirements for clean, high-load applications. - Thermal Management: Precision polishing of the roller end faces and a high-load-specific cage design reduce friction loss and effectively control working temperature rise (typical temperature rise ≤ 16°C); combined with the high-temperature stability of high-load-specific grease, this ensures the thermal stability of precision equipment under high loads. Installation Adaptability: The split inner and outer ring structure facilitates installation and preload adjustment, allowing for precise control of preload force through shims; the precision shoulder structure adapts to standard mounting surfaces and is compatible with standard interference fits (shaft h6/bore H7), meeting the assembly tolerance requirements of most heavy-duty precision equipment.
