1, to maintain the NSK Bearings and its surroundings clean. Invisible to the naked eye smile dust into the bearings, will increase the NSK bearing wear, vibration and noise.sealed ball bearing

2, using the installation carefully, do not allow strong punch, does not allow a direct hit with a hammer NSK Bearings, not allowed to transmit pressure through the rolling element.SKF bearing

3, the use of appropriate, accurate installation tool, try to use a special tool, try to avoid using the cloth and staple fiber and the like.

4, to prevent the corrosion of NSK Bearings, direct hand to pick up NSK Bearings, to fully wash away the sweat of the hands, and applied to high-quality mineral oil and then operate, with particular attention to anti-rust in the rainy season and summer.

The above is the point of attention in the NSK use the following to say about how to properly grasp the NSK Bearings skills

Available in four different stages, the UBR-AIR family of high precision air bearing rotation stages features a diameter that range from 100 mm to 270 mm, a profile height of only 55 mm and a load capacity of up to 40 kg. The UBR-AIR bearing stages are driven by a direct-drive torque motor and fitted with a reference class optical direct-metrology scale encoder. In addition, they also achieve angular resolution down to 0.00002 degrees, repeatability of 0.00003 degrees and a maximum velocity of 360 degrees per second.
