NTN bearings are an important part of the primary industrial equipment. Bearing problems can incur valuable stoppages; equipment damage and problems. In addition; large industrial bearings represent a lot of capital contribution.
In order to reach the high equipment function and the lowest protection cost, it is necessary to follow the correct disposal method. This includes bearing storage; eradication; cleaning; inspection and installation.
The service life of any NTN bearing depends to a large extent on the protection and protection of it. This is especially true in industrial applications; often the working conditions are harsh; the load is heavy; dust and pollution are common plans.
Suitable for all anti-collision bearing drawings. NTN bearing storage has unique anti-corrosion coating bearings available for selection; but most bearings are not corrosion-resistant materials. Bearings in handling and storage; it is necessary to be careful; to ensure that they will not be born Rust or corrosion. Even the hands or the few chemical gloves left behind by wet or unprotected contact can cause etching in a small area; this can cause bearing fatigue.
New and modified NTN bearings are shipped with a protective coating; usually in a cover paper or other packaging; and shipped in a carton or wooden box. When received into a new or modified bearing; do not pack it from the package until preparation The device is in the application program.
Do not store directly on the concrete floor; here you can condense the water collection and bearing. The pallets or bearings on the store shelves; the bearings are not subject to high humidity or sudden and severe temperature changes; can cause condensation to form the area.
Always put oil paper perhaps; if not; race plastic sheet in roller and tapered roller bearing cups.
Each type of NTN bearing is characterized by a common deletion process. Regardless of the bearing type; the bearing must be uniquely carefully removed. If it is not properly handled; it can damage the bearing; the shaft or casing; requires expensive repairs. Bearing; there is a driver to assist the bearing to be removed, etc.. About the tight fit; or press; or has been locked in a shaft local; can not mechanically remove the bearing puller; the inner ring of the bearing can be heated; to ease the move. Heat lamps or other heating equipment can be used. If it is a torch; it will change the function of the bearing steel and the bearing must be thrown away.
First, the use of the device should be carefully and carefully not allowed to force the stamping; the hammer is not allowed to directly hit the bearing; the pressure is not allowed to pass through the roll.
Second, use appropriate and precise devices to try to use special things; try to avoid the use of cloth and short fibers and the like.
Third, try to adhere to the health of the NTN bearing and its surrounding environment, even if the invisible shallow dust enters the bearing; it will also add bearing wear; oscillation and noise.
Fourth, to avoid the rust of NTN bearings directly take the NTN bearing by hand; to wash away the sweat on the hands; and apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust.
Under certain unique operating conditions; NTN bearings are able to obtain a better lifespan than traditional accounting; uniquely under light load conditions. These unique operating conditions are; when the rolling surface (track and roll) is smoothed by a film Effectively separating and restraining the appearance of contaminants can cause damage. In fact; under ambition; the so-called Eternal NTN bearing life is ok.

Nowadays, with the wide application of ceramics, the emergence of Ceramic Disc solves the problem of valve wear resistance. The ceramic disc is suitable for the dry ash system of the power plant and the feed pump of the warehouse pump. It can also be used for the opening and closing of various types of worn dry dust, water and other media in the mining, paper making and chemical industries. The ceramic feed valve is based on Armstrong valve technology and is sealed in any direction after closing. The ceramic disc is made of WCB steel castings and seamless steel pipe welding and packing with hard seals. Good sealing performance, strong wear resistance, small starting load, less ash and ashing, and long service life.
