K4×7×7 nylon bearing cage

 

Changzhou Zhiyue Plastic Co., Ltd. was established in 2010 and is located in Wujin District, Changzhou City, Jiangsu Province,with 15 years of experience in plastic cage production. Our factory specializes in the production and sale of various types of engineering plastic cages, with over a thousand product varieties and an annual sales volume of more than 50 million. All kinds of products have entered the markets of industries such as automobiles, bearings and furniture.

 

The main products currently produced by our factory are as follows: needle roller bearing nylon cages, one-way bearing nylon cages, nylon protective sleeves, flat thrust bearing nylon cages, nylon sealing rings, plastic inner plugs, and customized special structure products in furniture. We also undertake the customization of various non-standard plastic parts.

 

To ensure product quality, the nylon cages produced by our factory are made of special raw materials for nylon cages provided by BASF of Germany. We have the ability to independently open molds, which makes the efficiency of new product development and size adjustment higher. We also purchase and develop visual inspection equipment and projection inspection equipment to safeguard the quality of the products.

Q1: How does your factory ensure the quality of nylon retainers?
A: We implement a rigorous end-to-end quality control system:
Raw Material Management: Utilizing high-quality nylon raw materials from BASF with strict incoming inspection.
Process Monitoring: Real-time monitoring of critical process parameters (temperature, pressure, time) during production.
Comprehensive Inspection: Multiple inspection stages are performed, including but not limited to: visual inspection, full/sampling inspection of critical dimensions (using precision measuring instruments such as coordinate measuring machines and projectors), and functional testing (e.g., assembly testing).
Quality Certification: We continuously strive to enhance our quality management practices, comply with relevant industry standards (such as ISO 9001), and provide inspection reports upon customer request.

Q2: What is the maximum operating temperature for nylon retainers?
A: Standard nylon retainers (e.g., PA66-GF25/30%) typically have a continuous operating temperature range of -40°C to +120°C**. They can withstand short-term peaks up to +150°C. For higher temperature ratings (e.g., continuous >120°C or peak >150°C), we offer cages manufactured from specialized materials (e.g., PA66 + special heat stabilizers, PA46, high-temperature nylon, PEEK), significantly extending temperature resistance to +150°C to +250°C or higher.

Q3: What is the Minimum Order Quantity (MOQ)?
A: Our MOQ policy is relatively flexible:
Standard Products: Typically have lower MOQ requirements, with specific quantities depending on specifications and inventory availability.
Custom Products: MOQ primarily depends on mold costs and production complexity. For newly developed custom products, an initial production MOQ is required to amortize mold costs. We are committed to collaborating with customers to find the most cost-effective solution. Please provide your specific requirements, and we will offer detailed MOQ information and a quotation.

Q4: What is the typical production lead time?
A: Lead times depend on order quantity, product complexity, and current production scheduling:
Standard Products: Typically available from stock or with short lead times (e.g., 2-4 weeks).
Custom Products (requiring mold creation): Initial production cycles are longer, comprising mold manufacturing time (typically 4-8 weeks or longer, depending on complexity) + production time (2-4 weeks). Production time extends for large orders. Rush orders may be accommodated when capacity allows, subject to potential additional charges. We will provide a specific delivery schedule after order placement or confirmation.

Q5: How should I handle quality issues upon receiving the goods?
A: Customer satisfaction is our top priority. We offer comprehensive after-sales service and quality assurance:
Please inspect goods promptly upon receipt. If any quality issues are found, retain relevant evidence (photos, videos) and immediately contact our customer service or sales team within the warranty period specified in the contract (typically X days after delivery). We will respond swiftly to investigate the cause. If the issue is confirmed to be our responsibility, we will provide free replacement, restocking, or negotiate a reasonable compensation plan based on the circumstances. Our goal is to resolve all customer complaints efficiently and fairly.

Q6: Can you provide material certifications or test reports?
A: Yes, we can. Based on customer requirements, we can supply: Material Certificates of Analysis (COA) from raw material suppliers; Product dimensional inspection reports; Declarations or reports of compliance with environmental directives such as RoHS and REACH (where applicable). Please clearly specify your specific certification or report requirements when inquiring or placing an order.

Q7: How do I obtain a quote or initiate a custom project?
A: Obtaining a quote or starting a custom project is straightforward: Please provide your requirements in as much detail as possible, including:
Drawings or samples, material specifications (grade, color, special properties), quantity requirements (estimated annual consumption or initial order volume), application scenarios (bearing type, operating conditions), and any special requirements or standards. Our engineering and sales teams will promptly evaluate your needs, conduct feasibility analysis, and discuss details with you. For custom projects, we will provide a mold cost estimate. After confirming all details, we will issue a formal quotation.
