BK12 Bearing Block Ball Screw Support Block is an important component widely used in mechanical transmission systems, mainly used to support and stabilise the operation of ball screws to ensure smooth and accurate linear movement.BK12 Bearing Block can not only effectively carry axial loads, but also reduce vibration and friction to improve the efficiency and service life of the entire transmission system. This ball screw support unit also reduces vibration and friction and improves the efficiency.
The ball screw support block is a key component that connects the ball screw to the machine tool or equipment frame. Ball screw support unit's main function is to provide support for the ballscrew to prevent it from bending or shifting during operation, thus ensuring high-precision motion control. Ball screw support unit is often required at both ends of a ball screw to maintain its stability and ensure proper functioning. Ball screw support unit is usually designed with load capacity, wear resistance and ease of installation.
BK12 bearing block is a specially designed Ball screw support unit, which is usually made of high-strength aluminium alloy or steel with good strength and durability.The structural design of BK12 bearing block usually includes multiple mounting holes to facilitate the connection with the mechanical frame. In addition, BK12 bearing blocks are equipped with high-precision bearings inside, which can effectively reduce the friction and wear of ball screws and provide smoother running experience.
The BK12 support block has a wide range of applications. In CNC machine tools, the ball screw bearing block can effectively support ballscrews to ensure machining accuracy and stability. In automation equipment, BK12 support blocks provide stable support for moving parts. This stability is critical to improving productivity and ensuring product quality.
The installation of BK12 bearing blocks usually requires precise alignment to the specific requirements of the equipment to ensure that the load capacity of the ball screw bearing block is optimised. Proper installation and commissioning will maximise the performance of the BK12 Bearing Block, extend its life and reduce maintenance costs.
The importance of the BK12 Bearing Block Ball Screw Support Block in mechanical drive systems cannot be overstated. Ball screw bearing block is not only a key component for high-precision motion control, but also a guarantee for the reliability of the entire system. Through high-quality materials and precise design, the BK12 support block is able to provide excellent support performance and stability under high loads and high-frequency operation.
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.
