Plastic Bushing – Wound Fiberglass Bushing 20×23×10 mm
DALON’s wound fiberglass bushing in size 20×23×10 mm is a lightweight, self-lubricating plastic composite sleeve bearing designed for dry-running or marginally lubricated environments. Constructed from resin-impregnated fiberglass wound in layers, this bushing delivers outstanding wear resistance, strength, and dimensional stability even under continuous or oscillating motion.
Ideal for applications where metallic bushings are too heavy, overengineered, or prone to corrosion, this wound plastic bushing supports quiet, clean, and maintenance-free operation across diverse industries.
Material: Wound fiberglass + resin composite
Inner Diameter (ID): 20 mm
Outer Diameter (OD): 23 mm
Length: 10 mm
Lubrication Requirement: Dry or boundary-lubricated
Temperature Range: -40°C to +120°C (short-term +150°C)
Load Capacity: Medium load (up to 60 MPa depending on shaft and speed)
Friction Coefficient: ~0.1–0.2 (dry steel shaft)
Lightweight & Non-Metallic: Reduces overall assembly weight
Self-Lubricating: Suitable for dry running, no oil or grease needed
Corrosion Resistant: Performs well in moist or chemical-laden atmospheres
High Wear Resistance: Wound construction enhances durability under dynamic load
Low Noise & Vibration: Smooth operation in sensitive mechanical systems
Automotive pedals, HVAC systems, windshield wipers
Fitness equipment & office chairs
Textile and printing machinery
Food and beverage processing (non-metallic contact)
Agricultural or lawn equipment
Home appliances and industrial small machines

Q1: What is a wound fiberglass bushing?
It's a plastic bushing made by winding fiberglass layers into a tube shape and impregnating them with resin, creating a strong and lightweight sleeve.
Q2: Can it run without lubrication?
Yes. It's designed for dry-running applications, although marginal lubrication can extend service life.
Q3: Is it compatible with metal shafts?
Absolutely. It's commonly paired with hardened steel or stainless steel shafts and causes less wear on mating surfaces.
Q4: Can this be used outdoors?
Yes. It resists moisture and mild chemicals, making it ideal for outdoor and semi-exposed installations.
Q5: How does it compare to bronze or sintered bushings?
Plastic bushings are lighter, corrosion-free, quieter, and require no lubrication, while bronze offers higher load but needs greasing.
Q6: Do you offer custom sizes?
Yes. DALON supports full OEM customization in terms of inner/outer diameters, length, grooves, flanges, and slots.
