1: bearing grease methods:Note fat content on the sealing performance of a large number of tests that, when the amount of grease within the bearing cavity volume is about 30% or less, due to the internal bearing no saturated fat, so very little grease leakage. Note more than 30% fat, bearing the internal local produce saturation, when the grease reaches 50%, the bearing grease to reach full saturation, excess fat is "squeezed" out. Special attention,

1, bearing inspection and repair technology1, ntn bearing cleaning Bearing Maintenance imported under demolition, the first recorded appearance of bearing, lubricant residue confirmation sampling after checking with the lubricant, cleaning bearings. As cleaning agents, general use gasoline, kerosene. Remove the bearings to cleaning, sub-rough cleansing and washing small fine, were in the container, first put metal mesh bottom,

1: ntn bearing nature of the noise:1. Rolling sound and control the impact of large models of ball bearings or cylindrical roller bearings ntn pure radial load low speed operation, due to the centrifugal force rolling small area in the non-load rolling element will impact or roller and cage noises. But with the speed increase, this sound will disappear. Impact of sound on the ball control methods: the radial clearance appropriate to reduce the use of reasonable structure of the material is supple nature of the bearing cage.

Compared with plain bearings, deep groove ball bearings of the excellent Compared with plain bearings, deep groove ball bearings of the inferior 1, the general conditions, the efficiency and fluid dynamic bearing lubrication bearing considerable, but higher than the number of hybrid bearings;  1, less able to withstand impact loading; 2, radial clearance is small, angular contact bearings can be used to preload cardiac

ntn rolling bearings is the mass production of machine parts, and manufacture of precision is very strict for a high degree of technical specialization, thus readily available for most bearing varieties, should be purchased more cost-effective than repair, and only in the following situations Next, before considering the repair bearings, namely:1.ntn bearing a slight injury, such as inventory

1. Taper roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes taper roller bearings particularly suitable for the accommodation of combined (radial and axial) loads.2. Single row taper roller bearings can carry axial loads in one direction only. A radial load imposed on the bearing gives
