material selection recommendations for the metal-based embedded solid self-lubricating bearing (VSB650) based on specific application locations.

Material Selection for Specific Application Locations

 
 
Application Location Recommended Matrix Material (Code & Composition) Key Performance Basis Recommended Solid Lubricant Lubricant Characteristics & Applicability
Toggle bearings & tie-bar guide bushings in plastic machinery 650S5 / 650W3
(both CuZn25Al5Mn4Fe3)		 Medium-to-high load (75–100 MPa), high hardness (≥230–250 HB), high tensile strength (≥800 MPa), suitable for frequent start-stop and impact. SL1 (Graphite + additives) Excellent chemical stability, max. operating temp. +400 °C, suitable for general industrial applications with long-term exposure to air, meeting oil-free lubrication requirements.
Port machinery 650S2
(CuAl10Ni5Fe5 aluminum bronze)		 High-strength aluminum bronze, outstanding corrosion resistance, hardness ≥150 HB, suitable for humid, salt-laden environments. SL4 (PTFE + MoS₂ + additives) Excellent water lubrication performance, max. operating temp. +300 °C, ideal for port water mist and rain conditions, reducing friction. SL1 can also be used if moisture sensitivity is not a concern.
Hydraulic gates (water conservancy projects) 650S3 / 650S1
(650S3: CuSn12; 650S1: CuSn5Pb5Zn5)		 Tin bronze provides good corrosion resistance and wear resistance; 650S1 hardness ≥70 HB, load 50 MPa; 650S3 hardness ≥75 HB. Choose 650S2 if higher strength is needed. Priority: SL4 (Water-lubricating type) Specifically designed for water-lubricated conditions, can be used underwater or in ships, water turbines, etc., perfectly matching the immersion conditions of hydraulic gates.
Mining equipment 650S5 / 650W3
(CuZn25Al5Mn4Fe3)		 Heavy loads, dust, and severe impact in mining applications require high strength, high load capacity (75–100 MPa), and high hardness. SL1 (Graphite + additives) Graphite has high temperature resistance, tolerates dust, and has a relatively low friction coefficient, making it suitable for dry friction, high-load mining conditions.

Additional Notes:

  • 650 (Standard type) has a load capacity of 50 MPa and is suitable for medium loads in general industry. It can be chosen if the specific location has a relatively low load.

  • Lubricant selection logic: For locations with water contact (hydraulic gates, underwater port components), SL4 (PTFE+MoS₂) is preferred due to its excellent water-lubricating properties. For conventional industrial dry friction without water, SL1 (Graphite) is recommended, offering higher temperature resistance and cost-effectiveness.

  • Actual selection must be based on specific design loads, speeds, mating shaft materials, and ambient temperatures, with final reference to the technical data sheets and operating condition evaluations in the documentation.
