SWS BEARING LTD has strict requirements on bearing quality. Review each production process: material selection, processing, assembly, quality inspection. We are committed to producing high quality and low price products for our customers.
After years of development, SWS Bearing LTD now has a comprehensive set of quality testing equipment that can accurately measure bearing dimensional tolerances, roundness, maximum speed and clearance standards.
Quality inspection project
For products that have just been produced, we must first go through on-site inspection. We will use general tools to check the basic size information of each product. The main tools are: caliper 0.02mm, micrometer 0.01mm, dial gauge 0.01mm, dial gauge 0.001mm, Torsion spring table 0.001mm\0.002mm, fan-shaped table 0.01mm, etc.;
For more detailed bearing quality information, we will use the sampling method to conduct more in-depth testing using professional instruments. The main testing items are:
Acceleration vibration: S0910
Speed vibration: BVT-1A
Inner diameter: D922 D923
Outer diameter: D051
Inner ring width: G903
Hardness: Rockwell hardness tester
Metallographic organization: metallographic microscope
Surface roughness: roughness instrument
Surface roundness: roundness meter
Others: bearing life test, dustproof test of sealed bearings, leak test of sealed bearings
On request, each batch of orders will be tracked by a dedicated person and the results will be documented. Each shipment will be sampled and monitored before leaving the factory. All files will remain for more than 2 years.
