Feature:1. STABLE PERFORMANCE: The internal ball distribution of the slider is reasonable, the clearance is even, the use time is long and the performance is stable.2. SMOOTH SURFACE: The chamfer of the slider is rounded and the surface is uniformly smooth, burr free and highly accurate.3. QUIET SLIDING: The aluminum alloy sliding block has a high speed, no jamming, low friction and low noise when sliding.4. HIGH HARDNESS: The high purity of the slider, high wear resistance and contact fatigue strength, also retains good toughness to withstand high impact loads.5. WIDELY USED: Sliders are widely used in various industrial fields such as machine tools, construction machinery, robots, reducers, steel, metallurgy, textile, mining, printing, aerospace, etc.Specification:Item Type: Linear Ball Bearing Slide BlockMaterial: Aluminum alloyModel: SBR20UUApplication: The products are widely used in various industrial fields such as machine tools, engineering machinery, robots, reducers, steel, metallurgy, textile, mining, printing, aerospace, etc..Package List:2 x Linear Ball Bearing Slide Block
