Bearing 64450/64700 NSK Shielded bearings have a storage life of five years and a further two years operational life following installation. Wash all bearing parts with a noncontaminating solvent. Lightly pack the bearings with grease applying a 33% fill by volume into the bearing and housings. Where Bearing 64450/64700 NSK space heaters are fitted, and the storage environment has wide humi dity and temperature variations, it is strongly recommended they be energised. Warnings should be placed on the Bearing 64450/64700 NSK to make operatives aware of the live heaters Supplies are normally 220-240 volt single phase, from a 380-415 volt three phase supply. See terminal box lid for details.

Insulation resistance During extended storage a three monthly insulation test is recommended to avoid possible lengthy drying out periods when installing Bearing 64450/64700 NSK. Use a 500 volt d.c. Megger.The insulation resistance between phases and between the windings and the frame should be checked. The insulation resistance should be maintained above 10 megohm. If a lower reading is measured, use one of the drying out methods recommended on page 14 until an acceptable reading is obtained. If heaters are fitted but not energised, they should be used in future. Wound rotors Ideally, wound Bearing 64450/64700 NSK brushes should not be in contact with the slip-rings during storage as there is a risk of corrosion. Brushes should either be lifted off the slip-rings or stored separately. This may not be possible with small Bearing 64450/64700 NSK.

Fastenal Machinery Corporation is an ISO 9001:2008 certified company and a leading supplier of precision bearings and bearing related products across a large spectrum of customers. We supply a wide range of industries such as aerospace, medical, food processing, green energy, robotics, high tech, industrial products and many more.

Bearing 64450/64700 NSK use conical rollers guided by a back-face rib on the cone. These bearings are capable of taking high radial loads and axial loads in one direction.

Bearing 64450/64700 NSK are generally mounted in pairs in a manner similar to single-row angular contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting the axial distance between the cones or cups of the two opposed bearings. Since they are separable, the cone assemblies and cups can be mounted independently.

Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle.

Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.

Bearing 64450/64700 NSK has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads.
