Based on the model definition you provided (M = Standardized, I = Floating Diverter, F = Flanged Round Nut) and the naming conventions for ball screw specifications in the industry, the core parameters of this model are summarized as follows:
Nominal Diameter (Screw Outer Diameter): 8mm. The "08" in the model is a common industry designation, corresponding to a screw outer diameter of 8mm, which is a core indicator for load-bearing capacity and installation space.
Nut Structure: Flanged Round Nut + Floating Diverter. 1. Flange Design: Facilitates direct bolt fixing to the worktable for precise installation and positioning. 2. Floating Diverter (I): Optimizes the ball circulation path, reduces operating noise and torque fluctuations, and improves transmission smoothness.
Length Parameter: 265mm (Related to Screw Total Length/Effective Stroke). The "265" at the end of the model is a length identifier. According to industry practices, it most likely refers to the effective stroke or total length of the screw (specific values need to be confirmed by actual measurement), suitable for the stroke requirements of small and medium-sized equipment.
Thread Direction: Right-hand (Default). Unless otherwise specified, ball screws are uniformly right-hand threaded, meeting the movement direction requirements of most equipment. Left-hand threads can be customized if needed.
Rated Dynamic/Static Load: Refer to industry values for the same specification: Dynamic Load ≈ 1.3-2.3kN, Static Load ≈ 2.2-4.1kN. Derived based on industry general parameters for 8mm diameter + 2mm lead (specific values subject to manufacturer's actual measurement). The floating diverter structure optimizes load distribution and improves load-bearing stability.
Note: "98" is an auxiliary parameter. According to common industry labeling logic, it may represent the number of ball circuits (number of circulation loops) or indicators related to nut length (e.g., 9.8mm nut length). The specific meaning should be confirmed with the manufacturer's technical manual, and it primarily affects load capacity and installation space compatibility.
The parameter combination of this model (small-medium diameter/lead, standardized design, flanged installation, floating diverter) determines its core suitability for "high-precision, medium-light load, smooth operation" scenarios in small and medium-sized equipment, specifically including:
Typical Applications: Small CNC milling machines/engraving machines, desktop 3D printers, precision dispensing machines.
Adaptation Reasons: The combination of 8mm diameter + 2mm lead balances rigidity and precise positioning. The floating diverter reduces operating noise. The flanged nut facilitates quick installation and debugging. It can achieve ±0.01mm positioning error, meeting the accuracy requirements of 0.1mm layer thickness in 3D printing and precise glue dispensing position control in dispensing machines.
Typical Applications: PCB drilling machines, chip testing fixtures, electronic component placement machines (small workstations).
Adaptation Reasons: The standardized design (M) ensures component interchangeability, suitable for batch maintenance in production lines. The medium-small lead (2mm) enables low-speed smooth feeding, avoiding position deviation during electronic component processing/assembly. The low torque fluctuation characteristic of the floating diverter protects precision components from vibration.
Typical Applications: Small biochemical analyzers, medical imaging equipment (e.g., ultrasonic probe moving mechanisms), laboratory precision displacement platforms.
Adaptation Reasons: High transmission efficiency (≥90%) can reduce the power of drive motors, meeting the low-power requirements of medical equipment. The flanged installation structure ensures precise positioning, avoiding micro-deviation during equipment operation and ensuring detection/treatment accuracy. The standardized design meets the reliability and compliance requirements of medical equipment.
Typical Applications: SCARA robot end effectors, desktop collaborative robot joint transmissions.
Adaptation Reasons: The 8mm small-diameter design saves installation space, suitable for the compact structure of robots. The floating diverter improves dynamic response speed. Combined with a 2mm lead, it enables fast start-stop and precise positioning, supporting dynamic tasks such as picking and transporting for robots, with repeat positioning accuracy within ±0.02mm.
Typical Applications: Positioning mechanisms of small conveyor lines, automatic feeding devices, displacement tables of inspection equipment.
Adaptation Reasons: The flanged round nut is easy to install. The standardized design reduces procurement and maintenance costs. The medium-light load capacity is suitable for most general scenarios. The 2mm lead balances efficiency and stability, and it can replace traditional sliding screws to improve equipment service life and accuracy.
Accuracy Matching: For high-precision scenarios (e.g., laboratory equipment, precision machining), it is recommended to choose C3/C5 accuracy. For general machinery, C7 can balance accuracy and cost.
Load Limitation: This model is suitable for medium-light load scenarios (it is recommended that the actual load does not exceed 50% of the rated dynamic load) to avoid accelerated screw wear due to heavy loads, which may affect service life.
Installation and Maintenance: Ensure the flange mounting surface is flat during installation to avoid positioning deviation caused by uneven bolt locking force. Regularly check the ball circulation status of the floating diverter to prevent foreign objects from entering and affecting transmission smoothness.
Environmental Adaptation: Suitable for dry and clean industrial environments. If used in humid and dusty environments, sealing components and lubrication solutions should be used to extend service life.
