40 Steel Roller Track White Wheel Technical Drawing: Dimensions & Tolerances

What Is the 40 Steel Roller Track White Wheel?

In busy warehouses and assembly lines, the small components often make the biggest difference. The 40 Steel Roller Track White Wheel is one such component—quiet, durable, and designed to keep your operations moving smoothly. It's a core part of flow racks, conveyors, and lean systems, helping to reduce friction, speed up material handling, and minimize downtime.

Whether you're sorting parts in a 3C assembly plant or picking orders in a logistics center, this wheel ensures your goods glide gently and efficiently. Its white finish isn't just for looks—it's practical, too, making it easy to spot dirt and maintain cleanliness in sensitive environments like medical device manufacturing.

Technical Drawing Overview

Every 40 Steel Roller Track White Wheel we produce follows precise technical drawings to guarantee consistency and compatibility. These drawings aren't just lines on paper—they're a promise that each wheel will fit perfectly with your existing flow racks, conveyors, or lean pipe workbenches. Below is a breakdown of key dimensions from our official technical drawing:

Tolerance Specifications

Tolerances are critical for ensuring compatibility across your lean system. A tiny deviation can lead to jams, uneven wear, or even system failure. Our technical drawings define strict tolerances for every key dimension, so you never have to worry about misfits.

Material & Surface Finish

The 40 Steel Roller Track White Wheel is built to withstand heavy use. The core of the roller is made from cold-rolled steel (Q235), chosen for its high strength and rigidity. This steel core can handle loads up to 50 kg per roller, making it ideal for heavy boxes and components.

The white wheel itself is crafted from food-grade nylon (PA6), which is non-toxic, wear-resistant, and has a low friction coefficient. This material ensures smooth movement without scratching or damaging your products. The steel core undergoes galvanization to prevent rust, while the nylon wheel has a matte white finish that resists scratches and discoloration.

For added durability, the wheel is bonded to the steel core using a high-strength adhesive that won't break down under heat or pressure. This combination of materials ensures the wheel lasts for years, even in humid or dusty environments.

Compatibility with Lean System Components

This wheel is designed to integrate seamlessly with your existing lean system. Here are some key components it works with:

• Flow Racks: Perfect for our Material Rack B (3 row and 3 floor), where it helps move boxes and parts quickly during picking operations.
• Conveyors: Used in roller conveyors for 3C assembly lines, where small electronic components need to move gently without static buildup.
• Lean Pipe Workbenches: Pair it with Workbench E to create a small parts sorting station. The roller track can be attached to the bench's side, allowing parts to slide directly to the assembly area.
• Other Roller Tracks: Compatible with 40 steel roller tracks (green, yellow, grey) and 38 aluminum roller tracks, as long as the axle size matches.

Real-World Application Scenarios

Let's dive into how this wheel is used in actual industries:

• 3C Assembly: In a smartphone manufacturing plant, this wheel is part of a conveyor system that moves circuit boards from storage to the assembly line. The non-conductive nylon wheel prevents static damage to sensitive components.
• Medical Device Manufacturing: In a sterile environment, the white wheel is used in flow racks holding sterile packaging materials. Its clean finish and non-toxic material comply with health and safety standards.
• Warehouse Logistics: In a e-commerce warehouse, this wheel is used in picking stations where workers need to access items quickly. The white finish makes it easy to spot dirt and maintain cleanliness.
• Automotive Parts: In an auto parts plant, the wheel is part of a flow rack that holds small components like screws and bolts. Its smooth operation reduces the time spent retrieving parts.

Installation Guidelines

Installing the 40 Steel Roller Track White Wheel is simple, but following these steps ensures optimal performance:

1. Check the axle size: Ensure the axle is 6 mm in diameter, matching the wheel's axle hole.
2. Clean the axle: Remove any dirt or debris from the axle to prevent wear on the wheel.
3. Slide the wheel onto the axle: Push the wheel until it's flush against the track frame.
4. Apply lubricant: Use a small amount of silicone oil to the axle to ensure smooth rotation.
5. Align the wheels: Make sure all wheels are at the same height and parallel to each other to prevent items from getting stuck.

For maintenance, wipe the wheels down with a damp cloth every week to remove dust. Inspect the wheels monthly for signs of wear—if the nylon surface is cracked or the steel core is rusted, ｒｅｐｌａｃｅ the wheel immediately.

Quality Control & Testing

We take quality seriously. Every batch of wheels undergoes rigorous testing to meet our high standards:

• Load Test: Each wheel is tested to support 50 kg for 24 hours without deformation.
• Wear Resistance Test: The wheel is rotated against a rough surface for 10,000 cycles. It loses less than 0.1 mm of thickness.
• Smoothness Test: The friction coefficient is measured at 0.15, ensuring easy movement of goods.
• Corrosion Test: The steel core is subjected to a 48-hour salt spray test with no rust or corrosion.

All our products comply with ISO 9001 quality management standards, so you can trust their reliability.

Advantages Over Alternatives

Why choose the white wheel over other options?

• Cleanliness: The white finish makes it easy to spot dirt, which is critical for medical and 3C industries.
• Cost-Effective: If you don't need ESD protection, this wheel is a more affordable alternative to black ESD wheels.
• Durability: The nylon material is more wear-resistant than plastic wheels, lasting longer in heavy-use environments.
• Compatibility: Works with a wide range of lean system components, reducing the need for custom parts.

Sustainability & Lean Principles

This wheel aligns with our lean principles of reusability and continuous improvement:

• Reusable: If the nylon wheel wears out, you can ｒｅｐｌａｃｅ just the wheel instead of the entire roller, reducing waste.
• Recyclable: The steel core and nylon wheel are both recyclable at the end of their life.
• Continuous Improvement: We regularly ｕｐｄａｔｅ our design based on customer feedback. For example, we increased the wheel's thickness to handle heavier loads after requests from automotive plants.

Custom Solutions for Your Needs

Every business has unique needs. If our standard wheel doesn't fit your requirements, we offer custom solutions. Our engineers can design wheels with different sizes, materials, or finishes to meet your specific needs.

For example, a customer in the medical industry needed a wheel that could withstand high temperatures. We modified the nylon material to resist heat up to 120°C, ensuring it worked in their sterilization process. Another customer in the 3C industry needed a wheel with a smaller diameter—we adjusted the technical drawing to create a custom size.

Final Thoughts

The 40 Steel Roller Track White Wheel is a small component with a big impact. Its precise dimensions, durable materials, and compatibility with lean system components make it a reliable choice for any manufacturing or logistics operation.

Whether you're upgrading your flow racks, building a new conveyor, or need a custom solution, this wheel has you covered. It's designed to keep your operations efficient, clean, and sustainable—all while reducing costs and downtime.
