Wholesale Track Roller Bearings

Track Roller Bearings from Shanghai Yinin

Shanghai Yinin Bearing & Transmission Company is a wholesale Track Roller Bearings manufacturer and supplier with over two decades of bearing industry experience. We produce and export track roller bearings designed for linear motion systems, cam mechanisms, conveyor systems, and automation equipment. Our range includes SG, W, FR, LFR, and LV series, each engineered to meet specific load, speed, and environmental demands.

As an integrated manufacturer with our own factory in Jiangsu, we control quality from raw material to finished product. Our engineering team supports customization, and our sales group coordinates global logistics. We supply bearings to industries such as packaging, material handling, machine tools, and automotive assembly lines.

Our Track Roller Bearing Range

We offer five primary series, each with distinct characteristics for different applications. The table below summarizes the series and their typical uses.

Application Fit and Selection

Choosing the right track roller depends on load direction, speed, mounting space, and environmental conditions. For vertical loads on a flat track, SG or W series provide robust performance. If side loads are present, flanged designs like FR or LFR help maintain alignment. LV series suits compact linear guides where space is limited.

We consider factors such as operating temperature, contamination level, and required precision. Our engineers can recommend appropriate seals, lubricants, and internal clearance based on your specific operating profile.

Materials and Manufacturing

We manufacture track rollers from high-carbon chrome steel (GCr15) or stainless steel (AISI 440C) depending on corrosion resistance needs. The rollers are precision ground to achieve tight tolerances on outer diameter and raceway geometry. Heat treatment ensures hardness and wear resistance, while surface finishing reduces friction and noise.

Our factory uses modern CNC equipment and precision measuring instruments. Each production step is inspected, and finished bearings undergo dimensional, visual, and performance checks. For critical applications, we can perform vibration and noise testing as per customer requirements.

Engineering Support and Customization

We understand that standard catalogs do not always match your machine design. We offer customization in bore size, outer ring profile, width, and sealing arrangement. If you need a non-standard track roller, our technical team works with you to develop a drawing and specification that meets your application.

We also provide technical consultation on mounting, preload, and lubrication. Our goal is to ensure the bearing operates reliably throughout its service life.

Quality Assurance and Testing

Quality is embedded in our process. We start with strict incoming material inspection, including chemical composition and hardness verification. During machining, we monitor dimensions in real time. After assembly, we conduct noise and vibration tests on a sampling basis. For high-volume orders, we can implement full inspection according to your quality agreement.

We maintain a dedicated quality control team and testing laboratory. Our quality system follows international standards, and we continuously improve based on customer feedback and industry trends.

Packaging and Logistics

Proper packaging prevents damage during transit. We use rust-preventive oil, wrapping paper, and individual boxes or bulk cartons as per order size. For export, we pack in wooden pallets or crates to withstand sea freight. We coordinate with reliable shipping partners to ensure timely delivery to your port or warehouse.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following details from you:

• Bearing series and dimensions (or reference to a standard part number)
• Operating load (radial, axial, or combined) and direction
• Rotational speed (RPM) and duty cycle
• Operating temperature range and environment (dust, moisture, chemicals)
• Mounting arrangement and shaft/housing tolerances
• Required precision class and internal clearance
• Lubrication type (grease, oil, or special)
• Sealing requirements (open, shielded, or sealed)
• Quantity and target delivery schedule
• Any special testing or certification requirements

With this information, we can recommend the most suitable series, confirm technical specifications, and provide a competitive wholesale price.

Frequently Asked Questions

What is the difference between SG and W series track rollers?

SG series is designed for standard track and guide systems with a balance of load capacity and rigidity. W series is built for heavier loads and more extreme working conditions, offering higher radial and axial load ratings. We can help you compare specific load values based on your application.

Can you supply track roller bearings in stainless steel?

Yes, we can manufacture track rollers in stainless steel for applications requiring corrosion resistance, such as food processing or medical equipment. Stainless steel bearings have slightly lower load capacity than chrome steel, but we can advise on the best material for your environment.

What is the minimum order quantity for wholesale orders?

Our standard minimum order quantity is 100 sets for many in-stock items. For custom or non-standard bearings, the MOQ may be higher depending on manufacturing complexity. We can discuss your volume requirements to find a cost-effective solution.

Do you provide technical drawings or 3D models for integration?

Yes, we can supply dimensional drawings and 3D models (STEP or IGES) for our standard series. For custom designs, we will work with you to create and approve drawings before production begins.

How do you ensure consistent quality across large shipments?

We implement strict process control and inspect each batch. For large orders, we perform sampling inspection based on international standards, and we can provide inspection reports. If you require third-party testing, we can arrange that as well.
