Oct 22, 2018

                               FYH seat bearing dustproof and waterproof performance test


FYH conducted various tests to confirm the dustproof and waterproof performance of the rolling bearing with a seat. Representative test results are shown below. Dust throwing rotation test (dustproof performance) The drum-shaped dust throwing rotary tester is used to directly run the dust while throwing dust to the rolling bearing with the seat to judge the dustproof performance of the product. Rotating speed: 640 min-1 Load: only belt tension dust: aluminum powder (1000 [sieve] No.) Lubrication: No grease in operation, dusting, dusting, rotation test result (dustproof performance) After about 500 hours of operation of ordinary products Abnormal sound, you can conclude that it has invaded the dust. Correspondingly, the triple seal assembly (accessory mark L3) and the dust cover assembly (accessory mark C) did not produce an abnormality after 3,000 hours of operation, and exhibited excellent dustproof performance.

  The dust burying rotation test (dustproof performance) buryes the rolling bearing with the seat in the dust, and operates while stirring the dust with the impeller attached to the shaft to determine the dustproof performance of the product. The use conditions of the FYH seated rolling bearing under this test method are the most severe. Rotation speed: 640 min-1 Load: only belt tension dust: GC powder (500 [screen] No.) Lubrication: no grease in operation, no dust, no dust, no rotation test result (dustproof performance), about 200 hours after the operation of the ordinary product Abnormal sound, you can conclude that it has invaded the dust. Correspondingly, the triple seal assembly (accessory mark L3) and the dust cover assembly (accessory mark C) did not produce an abnormality after 2,000 hours of operation, and exhibited excellent dustproof performance.

  In the waterproof performance test, the impeller was operated while throwing water to the FYH-equipped rolling bearing to judge the waterproof performance of the product. Rotation speed: 380 min-1 Load: only belt tension Water: tap water Water resistance test results Example After about 1,000 hours of operation, the ball and raceway ring (outer ring and inner ring) can be found to rust. Correspondingly, after three hours of operation, the triple seal assembly (accessory mark L3) and the dust cover assembly (accessory mark C) showed the same degree of rust as the normal product.
