Fuwa Bushing 65*28

1. Function

• Wear and Corrosion Resistance: The nylon bushing is designed to reduce friction and wear between moving parts, and its corrosion-resistant properties make it suitable for harsh environments.

• Vibration and Noise Reduction: It can absorb vibrations and operate quietly, enhancing the stability and lifespan of machinery.

• Load Support: It provides structural support and can withstand specific loads without deformation.

2. Specifications

• Outer Diameter (OD): 65mm

• Inner Diameter (ID): 28mm

• Length: The length may vary depending on the specific design (e.g., some variants might be 57mm long, as seen in light-duty models).

• Color: Commonly available in black or yellow.

• Design: Typically cylindrical, but may include flanges or other features for mounting or alignment.

3. Material

• Nylon (PA6, PA66, or MC Nylon):

• PA6/PA66: Common nylon materials with good strength and wear resistance.

• MC Nylon (Monomer Casting Nylon): Offers higher mechanical properties, such as increased tensile strength and impact resistance.

• Modified Nylon: May include additives like lubricants, molybdenum disulfide, or graphite to enhance self-lubrication, wear resistance, or corrosion resistance.

4. Key Parameters

• Tensile Strength: Typically ranges from 40–90 MPa, depending on the nylon grade and any modifications.

• Hardness: Usually around 72–90 HRR (Rockwell Hardness R Scale).

• Max PV Value (Pressure-Velocity): 0.27–1.40 N/mm²·m/s, indicating its suitability for different load and speed conditions.

• Friction Coefficient: 0.08–0.26, contributing to its self-lubricating properties.

• Working Temperature Range: -80°C to +240°C, making it versatile for various environmental conditions.

• Load Capacity: The maximum load the bushing can withstand depends on its size, material, and design.

5. English Terminology

• Nylon Bushing: A type of bushing made from nylon material, used for reducing friction and wear.

• Outer Diameter (OD): The diameter of the outer surface of the bushing.

• Inner Diameter (ID): The diameter of the inner hole of the bushing.

• Tensile Strength: The maximum stress a material can withstand while being stretched or pulled.

• Friction Coefficient: A dimensionless scalar value that describes the ratio of the force of friction between two bodies.

• PV Value (Pressure-Velocity): A parameter used to evaluate the suitability of a bushing material for specific operating conditions.
