The Bosch Rexroth R162421322 is a high-precision ball linear guide slider, model KWD-025-SLH-C1-H-1. It features a narrow, long slider design (25mm), characterized by high rigidity, low friction, smooth operation, and low noise. Suitable for industrial applications such as CNC machining centers, automated equipment, and precision transmission platforms, it enables high-speed, high-precision linear motion control.
Features of the Bosch Rexroth R162421322 Long Ball Slider:
High-Precision Operation: Utilizes an H-class high-precision design, ensuring smooth operation and meeting the requirements for precise positioning and high repeatability.
High-Rigidity Structure: Exhibits high rigidity in all force directions, allowing for single-slider load-bearing in some applications.
Low Friction and Low Noise: The built-in ball chain design effectively reduces friction fluctuations and operating noise.
Smooth Operation: Optimized ball circulation and guiding structure ensure smoother and more stable slider movement.
Long-life lubrication: Factory pre-lubricated, enabling years of continuous lubrication and reducing maintenance frequency.
High interchangeability: Can be freely combined with Rexroth SNS/SNO series guideways, facilitating installation and replacement.
Suitable for confined spaces: The SLH narrow, long slider structure is suitable for equipment with limited horizontal installation space.
Applications of REXROTH R162421322:
Machine Tools: Such as machining centers and milling machines, requiring high guiding accuracy and rigidity.
Industrial Robots: Used for material handling and assembly, requiring high dynamic response and smooth movement.
Automation Equipment: Such as material handling, packaging machinery, and printing machinery.
Injection Molding Machines: Equipment requiring high rigidity and load-bearing capacity.
