ntn bearings require lubrication in order to ensure maximum service life, many users do not know how to lubricate bearings, causing premature bearing damage.ntn bearings bearing is not easy to bad lubrication is good, so so that bearing life is too short. Here is the relevant knowledge on the bearing area include the following aspects:1, first of all the various parts of the bearing lubrication, reducing bearing friction and wear;

1: ntn bearing deposit:1.ntn bearing the correct storage method is to ntn bearings placed in horizontal position, bearing ring should be supported throughout the side. If the bearing to the location of the vertical display, due to the relatively small thickness of bearing ring,bearing rings and rolling bodies may lead to bearing the weight of the permanent deformation.2. Stockroom of the relative humidity of not more than 60%, little change in temperature,

Incorrect installation and removal will reduce bearing life. When a small bearing assembly will enable the hand-hammer and a simple auxiliary sleeve. For medium and small bearings, installation of hydraulic machine can be used to exert pressure on the inner ring will be set to a journal on the bearing pressure for larger medium and large bearings, often used temperature method assembly

ntn Bearing selection of 4 Note1, carbon steel, high enough intensity, the lower the stress concentration sensitivity, easy to carry out a variety of heat treatment and mechanical processing, low price, supply adequate and there are the most widely used.The imports of general machinery bearings are available in 30,40,45,50 and other brands of high-quality carbon steel, particularly steel 45 after quenching the most commonly used.
 

Install thrust bearing, they should test shaft ring and shaft centerline perpendicularity. Method is to dial gauge fixed on the tank shell face, so touch the table top of the head ring in the bearing raceway upper rotating shaft bearings, side observation dial gauge pointer, if the pointer yaw show ring and shaft axis is not perpendicular to the centerline.

1: ntn bearing different Sound Detection:1., Vibration detection method: It is unusual sound of an indirect detection methods, detection can be divided into qualitative and quantitative parameters of detection. Among them, qualitative detection method is divided into monitoring and observation of abnormal sound vibration wave method

ntn bearings in high speed rotation, in particular the speed close to or exceeding the limits of record size of the table speed, the main should pay attention to the following(1) The use of precision bearings;(2) Analysis of the internal bearing clearance (taking into account the bearing temperature rise resulting reduction in the amount of internal clearance);(3) analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system.

Spherical Roller Bearings has a character of sell-aligning because the center of its raceway profile right fall on the center line of its bore diameter, even the shaft are bending slightly or the housing are inclining slightly, these errors of alignments cannot make the center of its raceway profile leave the center line of its bore diameter, this means the bearings can self-align,
