Try these tips for longer life from your
bearings
Keep new bearings in their original wrappings as long as possible and store them away from moisture where the temperature can be kept reasonably constant - just one in a series of tips from NSK

Guide helps users avoid bearing failures
Free publication deals with all aspects of bearing procedures, including handling of bearings, mounting, maintenance and inspection, dismounting and bearing storage.
Positioning technology allows microscopic handling
NSK's micro-manipulation system features a three-axis (XYZ) positioning stage that facilitates the attachment of measuring devices, micromanipulators and microscopes for examining a preparation.
For that reason, NSK advises that you keep new bearings in their original wrappings as long as possible and store them away from moisture where the temperature can be kept reasonably constant.
Cleanliness is key.
Anything that may come into contact with bearings should be kept clean, including workers' hands, benches, tools, solvents and cloths.
Perspiration, condensation - any type of moisture should also be kept away from bearings.
Handle bearings with clean, lintless cloths.
Protect bearings with an oil film and make every effort not to break that film.
Damage from compressed air.
Use extreme caution when using compressed air around bearings.
Compressed air is a source of moisture, which can cause corrosion in bearings.
Avoid nicks.
Make every effort to avoid nicking bearings, which can be caused by striking them with hardened steel tools or sharp objects.
Even though bearings are heat-treated, surfaces are brittle and fractures can easily occur.
Nicks on the exposed surfaces can cause bearings to be mounted improperly, which will reduce bearing life.
Observe these rules when mounting bearings.
A major load should never be applied through the rolling elements when mounting bearings.
Bearings should never be struck any blows with hardened steel implements.
Caution should be used to prevent loose particles from falling into bearings while being mounted.
This danger might occur on an arbor press or while using the drift tube technique.
In heating bearings for easier mounting, it is best to heat the bearing in an oven with circulating heat.
But at the same time guard against overheating the bearing.
Heating temperatures should, in general, not exceed 110C.
Proper lubrication is essential.
Proper lubrication is also critical in maintaining performance and longer bearing life. Request a free brochure from NSK UK ...
