· Product Overview
This precision-engineered cylindrical bushing is crafted from POM (Polyoxymethylene, also known as"Acetal"or"Delrin")—a high-performance engineering plastic valued for self-lubrication, low friction, and excellent wear resistance. CNC-machined to tight tolerances, it features a smooth cylindrical profile, a central through-hole (for shaft insertion), and a side positioning hole (for secure assembly locking). The matte black finish enhances durability while maintaining POM’s natural low-friction properties, making it ideal for applications requiring quiet, low-wear component interaction.
· Core Specifications
- Material: POM (Polyoxymethylene)
- Density: 1.41g/cm³ (lightweight for mechanical assemblies)
- Hardness: 85–95 Shore D (rigid yet impact-resistant)
- Coefficient of friction (dry): 0.15–0.3 (excellent self-lubrication, no additional grease needed for light loads)
- Operating temperature: -40°C to 100°C (stable in most industrial/household environments)
- Manufacturing Standard: ISO 9001-Certified
- Key Processes: CNC Turning + Precision Drilling
- Standard Parameters:
- Outer Diameter: 30mm (customizable 20–40mm)
- Central Hole Diameter: 15mm (customizable 10–25mm)
- Side Positioning Hole: M3 (customizable to M4)
- Dimensional Tolerance: ±0.02mm (ensures tight shaft fit)
- Surface Finish: Matte black (scratch-resistant, low-friction)
· Application Scenarios
This POM bushing excels in low-friction, low-noise applications:
- Mechanical Transmission Systems: Shaft liners, gearbox bushings, or conveyor system sliding components (reduces wear on metal shafts).
- Electronics Equipment: Internal component positioning sleeves, 3D printer extruder sliding parts, or control panel mechanism bushings.
- Furniture Hardware: Drawer slide bushings, cabinet hinge components, or adjustable shelf support sleeves (quiet operation).
- DIY & Hobby Projects: RC vehicle suspension bushings, custom jig sliding parts, or hobby robotics low-friction components.
· Production Process Introduction
- Material Cutting: Slice POM rods into cylindrical blanks matching the target bushing length.
- CNC Turning: Use precision CNC lathes to machine the outer cylindrical profile and central through-hole.
- Precision Drilling: Drill the side positioning hole (for assembly locking).
- Deburring: Remove sharp edges from holes and outer surfaces (ensures safe handling and smooth shaft interaction).
- Surface Finishing: Apply a matte black treatment to enhance durability and aesthetic consistency.
- Quality Inspection: Verify dimensional accuracy (via calipers/CMM) and check for surface defects.
· Packaging and Shipping Methods
- Packaging:
- Individual Units: Sealed in anti-scratch OPP plastic bags (preserves the matte finish and prevents dust buildup).
- Bulk Orders: Packed in foam-lined partitioned boxes (avoids collision, scratches, and deformation during transit).
- Shipping Options:
- Express Delivery (DHL/FedEx: 3–5 business days for sample orders).
- Air Freight (7–10 business days for small-batch production).
- Sea Freight (20–25 business days for bulk orders).All shipments include full tracking and damage insurance.
· Process
· Frequently Asked Questions (FAQ)
- MOQ (Minimum Order Quantity): 500 pieces for standard configurations; 200 pieces for custom designs (with valid technical drawings).
- Lead Time: Standard lead time is 7–10 working days (includes CNC machining and finishing); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
- Customization Capability: Full customization is supported—adjust outer diameter, central hole size, side hole specs, or modify the profile (e.g., add flanges) based on your needs. Our engineering team validates designs for friction performance and assembly fit.
