Henan San Kuang Machinery Technology Co., Ltd. proudly presents our high-performance Cross Roller Bearing Outer Diameter 100mm Inner Ring 50mm, specifically engineered for heavy load applications. With over a decade of manufacturing expertise since 2014, we combine precision engineering and robust materials to deliver bearings that excel in demanding environments. This product is designed to provide exceptional rigidity, rotational accuracy, and long service life, making it an ideal choice for industrial robots, machine tools, and heavy-duty automation systems.
Key Features & Technical Specifications
High Load Capacity: The crossed roller design distributes loads evenly, supporting both radial and axial forces simultaneously, making it suitable for heavy-duty applications.
Compact Design: With an outer diameter of 100mm and inner ring diameter of 50mm, this bearing offers a space-saving solution without compromising on performance.
High Rigidity: The cylindrical rollers are arranged perpendicularly, minimizing elastic deformation under load and ensuring stable operation.
Low Friction & Smooth Rotation: Precision-ground raceways and optimized roller geometries reduce friction, enabling high-speed rotation with minimal wear.
Customizable Precision Grades: Available in standard precision (P5) and higher grades (P4, P2) upon request, to meet specific application requirements.
Durable Materials: Manufactured from high-carbon chrome steel (GCr15) with optional cage materials (steel or brass) for enhanced durability and corrosion resistance.

Frequently Asked Questions
Q: What is the maximum load capacity of this bearing?
A: The dynamic load rating is approximately 45 kN, and static load rating is about 60 kN, though exact values depend on the precision grade and internal clearance. Please contact us for detailed calculations.Q: Can this bearing be used for high-speed applications?
A: Yes, with proper lubrication and precision grade, it can operate up to 3000 rpm. For higher speeds, we recommend selecting a higher precision class (P4 or P2) and appropriate lubrication.Q: Is the inner ring removable?
A: Cross roller bearings typically have an integral inner ring, but the design is split for easy mounting. The outer ring is also split, allowing for preload adjustment.Q: What materials are available for the cage?
A: Standard cages are made of steel, but brass cages are available as an option for improved wear resistance and quieter operation.Q: Do you offer custom sizes or modifications?
A: Yes, we can customize the outer diameter, inner diameter, width, and even the roller material. Minimum order quantities may apply.Q: What is the typical lead time for this product?
A: For standard models, lead time is 15–20 working days. Custom orders may require 30–45 days depending on complexity.Q: How do I ensure proper installation?
A: We provide installation guidelines and recommend using appropriate mounting tools. Our technical support team is available to assist with any questions.Q: Does this bearing require special lubrication?
A: Grease lubrication is typically sufficient for most applications. For high-speed or extreme temperature environments, oil lubrication may be recommended.
