Why Precise Linear Bushing Diameter Matters in Your Applications
Selecting the wrong linear bushing diameter can lead to premature wear, reduced accuracy, and system failures. Here are the critical challenges our clients face:
❌ Shaft-Bushing Mismatch
42% of linear motion failures occur due to improper diameter matching between shafts and bushings. Even a 0.1mm difference can cause vibration, noise, and reduced lifespan.
❌ Tolerance Confusion
Different standards (ISO, DIN, JIS) have varying tolerance classes for linear bushing diameters. Choosing the wrong tolerance can lead to seizure or excessive play.
❌ Material Incompatibility
Stainless steel bushings paired with carbon steel shafts can cause galvanic corrosion. Self-lubricating bushings may have different diameter requirements than metal versions.
❌ Load Capacity Misalignment
A bushing with the correct nominal diameter but insufficient wall thickness may fail under heavy loads. Dynamic vs. static load ratings must be considered.
❌ Speed Limitations
Higher speeds require tighter diameter tolerances to prevent excessive heat generation and premature wear. Standard bushings may not suffice for high-speed applications.
❌ Customization Costs
Non-standard diameters often come with high MOQs and long lead times. Our OEM/ODM services provide cost-effective custom diameter solutions with no minimum order.

Frequently Asked Questions About Linear Bushing Diameter
💡 Pro Tip: Use Ctrl+F (Windows) or Cmd+F (Mac) to search for your specific diameter (e.g., "20mm") in this section.
1. What is the difference between inner diameter (ID) and outer diameter (OD) in linear bushings?
The inner diameter (ID) is the shaft-facing dimension that determines compatibility with your rail or shaft. The outer diameter (OD) is the housing-facing dimension that fits into your machine's structure.
Example: An LME20 linear bushing has:
- ID: 20mm (±0.02mm) for the shaft
- OD: 28mm (standard housing size)
2. What diameter tolerances do your linear bushings meet?
Our bushings meet ISO, DIN, and JIS standards with the following tolerances:
| Tolerance Class | ID Tolerance (mm) | Best For |
|---|---|---|
| Normal (N) | +0.02 to +0.04 | General purposes, low-speed |
| Close (C) | +0.01 to +0.02 | Medium-speed, precision |
| Precision (P) | ±0.01 | High-speed, heavy-load |
| High Precision (H) | ±0.005 | Ultra-precision applications |
3. Can you provide linear bushings for a 20mm shaft? What are the exact dimensions?
Yes! For a 20mm shaft, we offer:
📌 LME20 Series (Standard):
- ID: 20mm (+0.02 to +0.04mm)
- OD: 28mm
- Length: 30mm, 40mm, 50mm, 60mm
- Material: Steel (GCr15) or Stainless Steel (440C)
- Max Speed: 100 m/min
- Load Capacity: 12,000 N
- ID: 20mm (0 to +0.02mm)
- OD: 30mm
- Tolerance: Precision (P) class
- Max Speed: 150 m/min
- ID: 20mm (±0.005mm)
- OD: 32mm
- Max Speed: 200 m/min
- Load Capacity: 18,000 N
4. How do I measure the diameter of my existing shaft for bushing selection?
Step-by-Step Shaft Measurement Guide:
- Clean the shaft: Remove dirt, grease, or burrs with a calibrated micrometer (0-25mm or 25-50mm range).
- Take 3 measurements:
- At the start of the bushing travel area
- At the middle
- At the end
- Record the smallest reading: This is your nominal diameter.
- Check for taper: If measurements vary by >0.02mm, your shaft may be worn or tapered.
- Compare with our chart: Select a bushing with an ID 0.01-0.03mm larger than your smallest measurement.
⚠️ Warning: Never use a vernier caliper for precision measurements - they lack the 0.001mm accuracy required for linear bushings.

5. What is the minimum order quantity (MOQ) for custom diameter linear bushings?
At YIDI Motion, we eliminate MOQ barriers:
📦 Standard Diameters (3-80mm):
- MOQ: 1 pc (for sampling)
- Bulk Discounts: Start at 50 pcs
- MOQ: 10 pcs (industry's lowest)
- Lead Time: 15-20 days
- Tooling Cost: Free for first-time orders
- No MOQ for annual contracts
- 100% customization (diameter, length, material, coating)
💡 Pro Tip: Order a sample set (5-10 pcs of different diameters) to test compatibility before bulk orders. We offer free samples for qualified buyers.
6. How does the linear bushing diameter affect load capacity and speed?
The diameter directly impacts two critical performance factors:
📊 1. Load Capacity:
- Larger ID = Higher Load: A 30mm bushing can handle 3-5x more load than a 10mm bushing.
- Wall Thickness Matters: Our bushings have optimized wall thickness for maximum strength.
- Material Impact: Stainless steel (440C) offers 20% higher load than standard steel (GCr15).
- Larger Diameter = Higher Speed: A 20mm bushing can reach 150 m/min, while a 50mm bushing can handle 200+ m/min.
- Tolerance Impact: Tighter tolerances (P or H class) allow for higher speeds by reducing vibration.
- Heat Dissipation: Larger bushings dissipate heat better, enabling sustained high-speed operation.
📈 Load vs. Diameter Chart (Steel Bushings, Normal Class):
| Diameter (mm) | Static Load (N) | Dynamic Load (N) | Max Speed (m/min) |
|---|---|---|---|
| 6mm | 1,200 | 800 | 60 |
| 10mm | 3,500 | 2,200 | 80 |
| 16mm | 8,000 | 5,000 | 100 |
| 20mm | 12,000 | 8,000 | 120 |
| 25mm | 18,000 | 12,000 | 150 |
| 30mm | 25,000 | 18,000 | 180 |
