FAQ
Q: What is the lifespan of these bushings?
A: Depending on the material and operating conditions, the lifespan generally ranges from 5-10 years.
Q: What is the delivery time?
A: Standard models are typically shipped within 7-10 working days, while custom products depend on specific requirements.
Q: Do you offer samples?
A: Yes, we provide samples for testing purposes.
Q: What are the main advantages of self-lubricating bushings in truck brake systems?
A: Self-lubricating bushings reduce friction and wear without the need for additional lubrication. This minimizes maintenance frequency, improves braking efficiency, and increases the overall lifespan of the braking system. They are particularly useful in environments where frequent lubrication is impractical.
Q: How do I choose the right bushing material for my truck's braking system?
A: The right material depends on several factors, including load capacity, operating temperature, environmental conditions (e.g., moisture, dust, or corrosion), and maintenance needs. For example:
- SF-1 Self-Lubricating: Ideal for medium-speed, low-load applications.
- Bimetallic: Best for heavy-load, high-impact conditions.
- Bronze: Suitable for wet or corrosive environments.
- Embedded Graphite: Performs well under high-temperature and high-frequency braking.
Q: Are your bushings compatible with all types of heavy-duty trucks?
Q: What is the difference between your standard bushings and custom-made bushings?
A: Standard bushings are manufactured in common sizes and materials to suit general applications. Custom-made bushings can be tailored in terms of dimensions, materials, surface treatments, and load capacities, providing optimized solutions for specific operational conditions.
Q: How should I maintain these bushings for optimal performance?
A: Although self-lubricating bushings require less maintenance, regular inspections are recommended to check for wear, debris buildup, or damage. In heavy-duty or corrosive environments, occasional cleaning may be necessary to maintain optimal performance.
Q: Do you offer bushings that comply with international safety and quality standards?
A: Yes, all our bushings are manufactured in compliance with ISO 9001 and TS 16949 quality management standards. They also meet relevant industry safety and performance regulations.
