Technical Support and Added Value Services
Our team delivers European engineering bearing support—design reviews, diagnostics, and preload tuning—so distributors can trust every cost effective China bearings shipment we certify.
Bearing Life and Fatigue Calculations
In applications where precise dimensions are critical, we provide consultation services to ensure the selected bearing dimensions align with the mechanical and load requirements of the system

Field Return Analysis
Our team has an extensive experience in field return analysis. Whatever happened to your bearings we can find it out


Clearance Reduction and mounting interference calculation
Proper fitting is crucial to prevent premature failure. Our fitting calculation service provides precise recommendations on tolerances, fits, and adjustments tailored to specific operational requirements. With the correct mounting conditions, clients can avoid common issues such as misalignment and improper load distribution, ensuring longer bearing life and smoother operation.
Frequently Asked Questions
What Clearance Should I use in my application
Clearance depends in the fitting of the bearing if the bearing is press-fit with high interference it will require high initial clearance
What bearing quality do I need?
Typically very highly loaded applications or high speed applications that stress bearings to the limit need very low vibration level (Z3V3) and possibly special greases and special filling rate
My bearing if vibrating what shall I do?
There are vibration analysis that can be performed without dismounting or even stopping the bearing. These are frequency vibration analysis. However they require special accelerometers and vibration analyzers
Is Standard grease enough for me?
Standard greases are fine for most of the applications. In case the bearing is heavily loaded, is working at high speed or temperature, a specially designed grease might be required. That does not necessarily mean more expensive grease.

Frequently Asked Questions
What Clearance Should I use in my application?
Clearance depends heavily on the fitting of the bearing. If the bearing is press-fit with high interference, it will typically require a higher initial clearance to accommodate the reduction in internal clearance caused by the fit. Our bearing technical support team can provide precise recommendations based on your specific application and mounting conditions.
What bearing quality do I need?
The required bearing quality depends on your application’s demands. Typically, very highly loaded applications or high-speed applications that stress bearings to their limit need a very low vibration level (e.g., Z3V3) and possibly special greases and a specific filling rate. We can assist you in determining the optimal quality for your needs, including considerations for predictive bearing maintenance.
My bearing is vibrating, what shall I do?
Bearing vibration can indicate various issues. There are vibration analysis techniques that can be performed without dismounting or even stopping the bearing, such as frequency vibration analysis. However, these require special accelerometers and vibration analyzers. Our rapid bearing diagnostics services can help identify the root cause of vibrations and recommend solutions.
Is standard grease enough for me?
Standard greases are suitable for most applications. However, if the bearing is heavily loaded, working at high speed, or operating at elevated temperatures, a specially designed grease might be required. This does not necessarily mean a more expensive grease, but one formulated for specific conditions. Our experts can provide bearing technical support to recommend the ideal lubrication for your application.
