Imagine this frustrating scenario: You’ve just installed brand-new high-speed precision angular contact ball bearings, expecting smooth, reliable performance. But instead, they quickly overheat — and then seize!
This was exactly the situation a customer brought to us at Beining Technology just two days ago. If you’ve experienced this issue, you’re not alone — and the root causes are often surprisingly simple.
As a leading manufacturer of precision bearings, we’ve identified the most common reasons behind bearing seizure:
1. Improper Installation
This is one of the most frequent causes.
Using excessive force or improper tools during installation can damage internal components such as raceways or rolling elements. Even slight deformations can disrupt the precise geometry required for high-speed operation, leading to increased friction, overheating, and eventually seizure.
✅ Tip: Always use proper press-fit tools and avoid hammering directly on the bearing.
2. Contamination Intrusion
Even microscopic particles can be disastrous.
Dust, metal shavings, or other debris entering the bearing during installation or initial operation can act like sandpaper, causing scoring, increased friction, and rapid failure — especially under high speeds.
✅ Tip: Ensure a clean working environment and inspect housing/seals before installation.
3. Incorrect Lubrication
Lubrication is critical — and getting it wrong can spell disaster.
Using the wrong type of grease (e.g., viscosity not suitable for speed or temperature), under-lubrication (leading to dry running), or over-lubrication (causing churning and heat buildup) are all common causes of bearing seizure.
✅ Tip: Follow manufacturer guidelines for lubricant type, quantity, and re-lubrication intervals.
4. Wrong Bearing Selection or Load Mismatch
"Just fitting" isn't enough.
Using a bearing not designed for your specific application can lead to premature failure. Too light a load may cause skidding of the rollers, while excessive load accelerates wear and generates heat. It’s crucial to match the bearing’s DN value, preload, and load capacity to the operating conditions.
✅ Tip: Consult with experts to ensure correct bearing selection based on speed, load, and precision requirements.
✅ Why Trust Beining Technology?
At Beining Intelligent Technology (Zhejiang) Co., Ltd., we go beyond being just a bearing supplier — we are your partner in precision motion solutions.
Our high-speed angular contact ball bearings are manufactured to the strictest tolerances and tested under real-world high-speed conditions. Designed for applications requiring torque accuracy and spindle stability, our products deliver the reliability your machines demand.
Prevention Is Key
To prevent seizure:
- Handle bearings with care using proper tools.
- Maintain a clean installation environment.
- Use the correct lubricant and apply it precisely.
- Choose bearings that match your application’s speed, load, and precision needs.
If you’ve checked these factors and still experience issues, deeper technical analysis may be needed.
