💡【SKU Dimension Selection Guide】

The drop-down menu parameters follow the technical drawing format: 【d x D x H x B x T】 (all dimensions in mm):

1. Parameter Breakdown:

   • d (Inner Diameter / Bore ID): Mating shaft diameter

   • D (Outer Diameter / Sleeve OD): Housing bore press-fit diameter

   • H (Total Height / Length): Overall bushing length

   • B (Flange Diameter): Outer diameter of the integrated thrust flange collar

   • T (Flange Thickness): Thickness of the axial thrust collar

2. Example Calculation (e.g., 5 x 7 x 8 x 11 x 2mm):

   • Corresponds to: Bore ID 5mm × Sleeve OD 7mm × Height 8mm × Flange OD 11mm × Flange Thickness 2mm

3. Ordering Tip: Verify both your shaft diameter (d) and mounting housing bore (D) prior to selecting your required dimension set from the menu.

🛡️ Key Features

• 🖤 Maintenance-Free Self-Lubrication: Embedded solid lubricant plugs release micro-particles during friction, creating a self-renewing, dry-running film without external grease or oil supply.

• 🔘 Integrated Flange for Axial Thrust & Locating: The integral flange shoulder provides positive axial positioning and simultaneously supports unidirectional thrust loads, eliminating separate thrust washers.

• 🦾 Superior Heavy-Load & Anti-Galling Capacity: Specifically designed for low-speed oscillating or reciprocating applications where traditional fluid oil films rupture; prevents shaft seizure and galling under extreme contact pressure.

• 🌡️ High-Temperature & Hostile Environment Stability: Resistant to lubricant evaporation, atmospheric moisture, and mild contaminants; ideal for high-heat ovens, furnaces, and outdoor linkages.

⚙️ Applications / Usage

• 🏭 Tool & Mold Making: Plastic injection mold guide pin bushings, stamping die slide plates, and ejector guide sleeves.

• 🚜 Construction & Heavy Machinery: Excavator pivot pin bushings, front-loader linkages, hydraulic cylinder trunnions.

• 🤖 Industrial Automation & Robotics: Articulated robotic arm joints, automated indexing tables, and cleanroom handling slides.

• 🍞 Food & Pharmaceutical Equipment: Oilless conveyor lines, bottling plants, and bakery ovens where liquid oil contamination is strictly prohibited.
