    Product number:
    MR74-ZZ, MR106-ZZ, MR117-ZZ, 684-ZZ

    Application conditions:
    1)These bearings are used on an encoder with medium to low rotating speeds and a clean operating environment. Their needs included small starting torque, low noise and should not leak grease. The customer previously used P5 and Z3 grade products of a well known Japanese firm. Though the encoder is small, the bearing's cost occupied a large portion of the total cost. After analyzing, WD suggested and provided Z2 products without abnormal noise to meet customer's operational requirements, which significantly reduced the cost.
    2)WD improved the design of the grease seals to satisfy the anti-dust, anti-leak requirements of the application. This helped to strengthen the relationship between WD and the customer and helped to achieve a win-win situation. WD Brand won this customer's trust.
    WD product advantages:
