OEM Size Viton Quad Ring

Product Details: X-Rings, or Quad-Rings, are a type of seal with a four-lobed design. They are dimensionally the same as standard O-Rings but have different groove requirements. X-Rings are known for requiring less squeeze, which results in less friction and wear on the seal. They are available in various sizes, including those corresponding to US standard AS568 O-ring numbers. The groove dimensions for X-Rings are typically deeper and narrower compared to O-Rings to prevent spiral failure[2][5].

Pros:
– Less squeeze required, resulting in less friction and wear on the seal.
– Better resistance to spiral failure compared to O-Rings.
– Suitable for both static and dynamic applications.
– Available in a wide range of sizes, including standard and non-standard dimensio…

Cons:
– May require specific groove designs which can be different from those for O-Ring…
– Can swell in certain applications, requiring adjustments in groove width.

O-ring & X-ring sealed chains Manufacturers

Product Details: O-ring and X-ring chains are types of sealed motorcycle chains designed to improve performance and reduce maintenance. O-ring chains feature cylindrical seals between the inner and outer link plates to retain lubricant and keep dirt out. X-ring chains use an ‘X’ shaped seal, which reduces friction and power loss compared to O-ring chains. Both types are self-lubricating, protecting the pins and rollers from metal-on-metal contact and debris. X-ring chains have a lower friction design, better durability, and longer lifespan than O-ring chains.

Pros:
– Self-lubricating, reducing the need for frequent lubrication and cleaning.
– Seals keep lubricant in and dirt out, extending chain life.
– X-ring chains have lower friction and better durability compared to O-ring chain…

Frequently Asked Questions (FAQs)

Here are five frequently asked questions about manufacturing in Chinese factories, along with clear and concise answers

Are Chinese factories just sweatshops with poor working conditions?

While it’s true that some Chinese factories have been accused of mistreating workers, the majority of factories in China operate within the law. The Chinese government has established labor laws to protect workers, and labor standards in many factories are rising to match those of Western countries. Reputable sourcing companies ensure they do not work with factories that exploit or violate labor laws.

Do Chinese factories produce low-quality products?

No, many Chinese factories produce high-quality products that meet international standards. Several prominent global brands source their products from Chinese factories, which have invested heavily in modern manufacturing equipment and technology. This investment has enabled them to produce goods that are comparable in quality to those made in Western countries.

How long does it take to find a suitable manufacturer in China?

The time it takes to find a suitable Chinese manufacturer can vary, but it typically takes a few weeks. This involves defining your product requirements, researching potential factories, evaluating their credentials, and requesting samples and quotes. Working with a sourcing agent can streamline this process and ensure you find a reliable supplier.

What are the typical payment terms when dealing with Chinese suppliers?

Typical payment terms with Chinese suppliers usually involve a 20-40% deposit upfront before production begins, with the remaining 60-80% paid before shipping. It’s recommended to route payments through a trusted agent to ensure secure and reliable transactions. Clear payment terms should be negotiated and agreed upon before starting production.

How do you ensure quality control when manufacturing in China?

Ensuring quality control is crucial when manufacturing in China. You should implement rigorous product quality inspection protocols, which can include conducting inspections during various stages of production, from raw materials to finished goods. Using third-party inspection services or a sourcing agent can help ensure that the products meet your specifications and quality standards. Regular communication and feedback with the supplier are also essential for maintaining high-quality output.
