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. QUIET SLIDING: The aluminum alloy sliding block has a high speed, no jamming, low friction and low noise when sliding. 3. HIGH HARDNESS: The high purity of the slider, high wear resistance and contact fatigue strength, also retains good toughness to withstand high impact loads. 4. SMOOTH SURFACE: The chamfer of the slider is rounded and the surface is uniformly smooth, burr free and highly accurate. 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: Open Sliding Ball Bearing Block Material: Aluminum alloy Model: SBR25UU Application: 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 Open Sliding Ball Bearing Block
