Full Copper Guide Sleeve With Oil Groove, Suitable For The Mold Industry
Overview
Our straight bronze bushing is manufactured from premium copper alloy such as high-strength brass, tin bronze, aluminum bronze or high-leaded bronze. Made via strict CNC precision turning, this plain sliding bearing features excellent wear resistance, high compressive strength, good thermal conductivity and corrosion resistance.
It is a simple cylindrical one-piece structure without flange, easy to press-fit into housing bore. Suitable for heavy-load, low-speed rotating or oscillating motion, widely used as replacement of standard solid bronze plain bearings.
Key Features
✅ Premium Copper Alloy Material: Optional high-strength brass, tin bronze, aluminum bronze, high leaded bronze. High load capacity & impact resistance.
✅ Precision CNC Machining: Surface roughness Ra0.4~Ra1.6, tight tolerance control, smooth inner bore to reduce friction loss.
✅ Straight Cylindrical Structure : Simple cylindrical design, convenient for press fitting installation.
✅ Excellent Wear & Corrosion Resistance: Longer service life under heavy load, dusty or humid working conditions.
✅ Customization Available: Custom inner diameter, outer diameter, length, oil grooves, oil holes per drawings or samples.
✅ Wide Application: Fit for engineering machinery, hydraulic cylinders, injection molds, automation equipment, machine tools, excavator hinge joints, textile machines and more.
Application Fields
- Plastic injection molds, die casting molds (middle guide bushing / ejector guide bush)
- Injection molding machines, hydraulic equipment
- Automation machinery, packaging & textile equipment
- Construction machinery, excavator hinge joints
- Automotive, metallurgy and mining equipment
