BK20 Bearing Block Ball Screw Support Block is one of the key components in the ball screw drive system, which is widely used in CNC machine tools, automation equipment and other high-precision machinery.BK20 Bearing Block is mainly used for supporting and fixing the ball screw to ensure its stability in the working process, The BK20 bearing block is mainly used to support and fix the ball screw to ensure its stable and smooth operation during the working process. Using the lead screw bearing block can avoid bending or deviation of the ball screw which may affect the precision and performance of the system.
The BK20 support block plays a vital role in CNC machine tools and other high-precision automation equipment. By stabilising the ends of the screw, it prevents the screw from bending or juddering at high speeds, thus improving machining accuracy and productivity. Especially in applications that require high loads and long strokes, the high load carrying capacity of the BK20 provides long term stable support for the machine.
Mounting of BK20 bearing blocks is usually relatively simple, but to ensure optimum performance, mounting requires precise alignment of the ballscrew with the machine frame.
Load capacity is determined by dynamic (C) and static (C₀) load ratings. For example: A 6205 deep groove ball bearing has a dynamic load rating of 14 kN, suitable for small motors. For heavy loads, choose tapered roller bearings (e.g., 32208 with C=90 kN). Recommendation: Share your equipment’s load analysis for optimal bearing selection.
Materials: Stainless steel (440C/316) or coatings (nickel plating, DLC). Seals: Double rubber seals (2RS) or PTFE seals. Example: Seawater pumps often use 316 stainless steel bearings with lifelong grease.
Speed limits depend on bearing type and lubrication: Standard 608ZZ ball bearings: ~18,000 rpm. Hybrid ceramic bearings (Si3N4 balls): 30–50% higher speeds. Solution: For high-speed applications, opt for oil lubrication or low-friction design.
Theoretical lifespan: Based on load calculations (see Q1). Real-world factors: Lubrication intervals (e.g., grease replenishment every 100km). Mounting surface flatness (≤0.01mm/m required). Tool: Free lifespan calculation software available.
Must-check: Slider hole spacing (e.g., 45mm×45mm). Rail width (15/20/25mm, etc.). Slider height (impacts machine space). Pro tip: Old slider model numbers are often engraved on the side.
