INA bearings is properly installed, which will affect accuracy, longevity, performance. Therefore the design and Assembly departments for bearing installation the full study. Want to be installed in accordance with operational standards. Job standards projects often are as follows:
(1), cleaning associated bearings and bearing components
(2), check the size and finishing of associated parts
(3), installation
(4), once the bearing is installed check
(5), the supply of lubricants
Hopes in the forthcoming before installation, just open the bearing package. General grease lubrication, no cleaning, filling grease directly. Lubricating oil, ordinary or cleaning, however, instruments or INA bearings used in high speed, to use clean oil wash, dropping the antirust coating on the bearing. Bearings removed rust, rust, so cannot be placed aside. Furthermore, into the bearings with grease, no cleaning used directly.
Bearing installation methods, by INA bearings structure, fit, vary depending on the conditions, in General, due to rotate, so the interference fit is required for the inner rings. Bearings with a cylindrical bore and more with presses onto, or multiple-use and charging methods. Tapered bore, mounted directly on tapered shaft or sleeve installation.
When you install into the shell, General clearance, there is interference in the outer ring, normally, the pressure into pressure, or have installed after the cooling methods of shrink fit. Using dry ice as a cooling agent, shrink fit occasion, moisture in the air will condense in the INA bearings surface. So, you need appropriate antirust measures.
In some specific devices often require high temperature resistance in high temperature environments, large clearance of bearings, but the user how to measure INA bearings radial clearance? Briefly below:
(1) in the measurement process should guarantee the ball falling into the ditch; closed type bearings in front of the closed measurements; when a Dutch instrument, measuring value by subtracting the load caused by increased clearance.
(2) for multiple-row bearings requiring clearance qualified in each column, taking the arithmetic average of the clearance as the INA bearings radial clearance.
(3) as far as possible using special instruments and measurements;
(4) hand-push-method for measuring the requirements of measuring higher measurement skills. This method of measurement error is large, especially when clearance of marginalized, prone to error, in which case the instruments shall prevail;
(5) the examiner when measuring, operation should be according to the provisions of the standard may not be used to roll past methods of measurement on the roller from the examiner.
