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.
