Proper Bearing Storage and Installation Tips

Posted by Richie Capeles on Jan 4, 2016 10:55:52 AM

While CoVest wants our members to find the best MRO savings, we'd also like to help our members with their practical application of these categories. In collaboration with Motion Industries and their instructive video series MiHOW2, we've provided information on how to properly store and install bearings below.

Implementing proper storage will reduce the chances of damage before installation and ensure that your bearings will meet their intended shelf life. Because bearings are supplied as precision machine components, they should be respected and treated as such. Implementing the following storage rules is key.

  • Don't take any chances! If the external packaging is significantly damaged, return the bearing for replacement. Considering replacing bearings if package is:
    • Dented or torn 
    • Dirty, faded or oily
    • Written upon
    • Has open tabs
    • Product label or bar code is ineligible
  • The storage area needs to be cool! Make sure the stocking area has a steady temperature with controlled humidity. 
  • The area should be vibration and draft free
  • Bearings should be stored flat, preferably with adjustable shelves
  • Most importantly, employ the "first in, first out" organizing rule 


Bearing Installation

The proper method of bearing installation could maximize bearing efficiency and save money. Almost 30% of premature bearing failures are due to poor installation and handling. First let's review the steps of installing a bearing:

  • Apply oil to the shaft 
  • Place bearing on shaft
  • Take collet tool and put it on top of bearing
  • Use dead blow hammer to advance the bearing to the proper location on the shaft 

Follow these installation tips to ensure your bearings are in tip-top shape:

  • Hands off! Do not let bare hands come in contact with the bearing. Skin contact could cause  corrosion in the steel. 
  • If unsure of which size impact ring (or collet) to use and you do not have an informative chart follow these steps:
    • Make sure the bore (hole) is larger than the shaft
    • Make sure the outside diameter of the collet is approximately the size of the ring you’re driving
    • You should have clearance over the shift as well as meet up with the driving surface of the bearing
  • Do not drive through the rolling elements. Always drive on the portions of the bearings that is being fitted
  • When you drive a bearing, you always want to make sure its seated against the shoulder
  • Make sure the bearing has maintain its internal clearance when seated on the shoulder by spinning the bearing
  • Never strike a bearing directly with harden steel or brass hammer because harden steel could damage the bearing and brass could flake off and get into the bearing. Use a dead blow hammer 

Always remember to wear the proper PPE (Personal Protective Equipment) when handling MRO equipment. Learn more about workplace injuries and prevention, here.
