NES is home to the largest independent bearing testing facility in North America. NES’s complete testing facility includes over 50 unique bearing test rigs encompassing well over 100 test bearing locations. NES has the ability to custom build a test rig to your specific application as well as the resources to test any ball or roller bearing ...
General Bearing Corporation’s test lab focus is on new product development. Engineering Designs developed at our West Nyack, NY headquarters are manufactured at our factories in China. Design validation through testing is then carried out either in our NY test labs or at our new Engineering & Technology Center in Xinchang China under the supervision of the Design Engineering group.
This test was developed by the California Division of Highways of the United States. California Bearing Ratio is defined as the ratio of force per unit area that is required to penetrate a soil mass with a piston of 1.25mm/min corresponding to that required for the penetration of a standard material. CBR = (Test load/Standard load) * 100
As a bearing test laboratory, HBRC is a third-party organization independent of the bearing using, manufacture, and sale. HBRC covers a testing area of 2000 square meters and is equipped with 150 sets of inspection & testing machines.
The second important bearings parameter is the limiting rotational speed (limiting speed frequency). This parameter is tested on special testing stands. During the test there are checked the maximum speed values under which the bearing operates fail-safed and under a steadfast thermal balance. Special Tests
To help mitigate failures and provide remedial action, AST can expertly examine, test, and analyze a wide range of bearing performance parameters in our laboratories. We can perform bearing failure analysis on your bearings regardless of brand, and even if they were sourced elsewhere.
CALIFORNIA BEARING RATIO TEST 1.Objective CBR is the ratio expressed in percentage of force per unit area required to penetrate a soil mass with a standard circular plunger of 50 mm diameter at the rate of 1.25 mm/min to that required for corresponding penetration in a standard material. The ratio is usually determined for penetration of 2.5 and 5 mm .

Test Method: ASTM D4767 – 11 / D2850 Plate Bearing: In the design of shallow foundation or traffic surface, design engineers need to know the bearing capacity of soil underneath. To serve this purpose, a plate bearing test is carried out in the field. Results from the test can be used to design parameter or confirm the design of assumption.
The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress.
