NSK bearing catalogue showed many bearing types, such as cylindrical roller bearings,  ball bearings, bearing for Mining machinery,  Railway bearings , spherical roller bearings etc.

 

Besides of bearing types, the catalogue also showed bearing sizes. Many suffix like C3, C4, K, CC/W33, P4, as well as how much is the bearing load capacity and limited speed, all these bearing sizes can be checked out.

 

The savings are the result of work with NSK, using its AIP (asset improvement programme), which reviews bearing problems in production environments.

 

The drilling unit problem centred on its rear bearings, which repeatedly failed after three to four months – resulting in unplanned and costly downtime running at €500/hour and rising to €3.750 per year on a single drilling rig.

 

NSK engineers found that the sealed rear bearings were failing because they were rotating at a higher speed than that specified (10,000rpm). They suggested fitting the bearings with non contact seals to achieve maximum speed with minimised friction.

 

“If operating life is to be maximised, the type of seal employed must be chosen not only with the operating conditions in mind, but also with the frictional effect the device will have upon the bearing starting and running torques,” advises a spokesperson.

 

Now we know there are many considerations like the form and design, arrangement of bearing components, internal clearance, seals, lubricant, and methods of installation and removal on the bearing catalogue. If you want to choose NSK bearings, email us for the bearing catalogue.
