The REXROTH R162421422 is a 25-size, SLH (slim, long, tall) steel heavy-duty ball slide, model KWD-025-SLH-C1-N-1. It features C1 preload and N-class standard precision and is equipped with a ball chain to reduce noise.
Bosch Rexroth R162421422 Ball Slide Features:
High Precision Operation: Designed for N-class standard precision, ensuring smooth operation and meeting the requirements for precise positioning and high repeatability.
High Rigidity Structure: High rigidity in all stress directions, allowing for single-slide load bearing in some applications.
Low Friction and Low Noise: Built-in ball chain design effectively reduces friction fluctuations and operating noise.
Smooth Operation: Optimized ball circulation and guide structure ensure smoother and more stable slide movement.
Long-Life Lubrication: Factory pre-lubricated, allowing for years of continuous lubrication and reducing maintenance frequency.
Highly interchangeable: 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 lateral installation space.
Applications of REXROTH R162421422:
Machine tools: Such as machining centers and milling machines, requiring high guiding accuracy and rigidity.
Industrial robots: Used for handling and assembly robots, 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.
