     Tips: Things to Consider before Choosing a Linear Bearing

    You should consider the factors below when you choose a particular bearing for specific applications:

    • Dimensions
      Bearings with incorrect sizes will not deliver the best performance so you have to choose the right bearing of matched dimensions according to your requirement.
    • Load Capacity
      Load-bearing capacity varies depending on different types of linear bearings. Applying proper load on the bearing as prescribed helps extend its lifespan.
    • Temperature
      The bearing that you're supposed to choose should be able to withstand the temperature ups and lows during the performance. Operating temperature is a significant parameter worth considering since the neglect of it can be hazardous for health and durability of the bearing.
    • Speed
      The operating temperature of the bearing plays a major part in the conditioning of speed.
    • Lifespan
      The lifespan of an ideal bearing should convince you to invest in it.
