Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.
Tapered roller bearings are uniquely designed to manage both thrust and radial loads. Consisting of a "tapered cup" and a "tapered cone", this design is one of the most basic and common styles in the bearing industry. Found in everything from cars to conveyor lines, tapered roller bearings are more versatile than any other bearing series. Our taper bearings are sold in sets with both the cup and the cone together.
tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing. Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN`s tapered Roller Bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads. With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it`s no wonder that NTN rivals all major competitors on the market.
We offer premium tapered roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of [Bearing Quality" to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you`re looking for an American-made, case-carburized inch series taper, or a metric series through-hardened variety, we have you covered with a proper fit for your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.

1. Farmhouse fertilizer. Refers to fertilizers containing a large amount of biological substances, animal and plant residues, excreta, biological waste and other substances.
1. Composting. An organic fertilizer made up of various types of straw, deciduous, human and feces as raw materials and a small amount of soil.
2, fat fertilizer. The materials used are basically the same as those of compost, but they are fermented under flooding conditions (animality).
3. Manure. It refers to the manure and straw of the pigs, cattle, horses, sheep, ducks and other livestock and poultry.
4. Biogas fertilizer. In the sealed biogas digester, organic matter is decomposed under anaerobic conditions to produce by-products of biogas.
5, green manure. The use of cultivated or wild green plants as fertilizers is mainly divided into two major categories: legumes and non-legumes, such as mung beans, broad beans, and grass mites. Non-legume green manure is most commonly used in grasses such as ryegrass; cruciferae such as fat radish.
6, crop straw. The crop straw contains a considerable amount of nutrient elements (n, p, k, ca, s, etc.) which are mineralized by the action of soil microorganisms under suitable conditions and then returned to the soil for absorption and utilization by the crop.
7, mud fertilizer. Uncontaminated river mud, pond mud, ditch mud, port mud, lake mud, etc.
8, cake fertilizer. Rapeseed cake, cottonseed cake, bean cake, sesame cake, peanut cake, castor cake, tea seed cake, etc.
2. Commercial fertilizers.
1. Commercial organic fertilizer. It refers to commercial fertilizers produced by processing a large amount of biological substances, animal and plant residues, excreta, biological wastes and other materials.
2. Humic acid fertilizer. Refers to fertilizers containing humic acids such as peat (pitch), lignite, and weathered coal.
3. Microbial fertilizer. Refers to the production of an active microbial preparation by the cultivation of a specific microbial strain to improve the nutrition of the plant or to produce plant growth hormone to promote plant growth by the life activities of the specific microorganism.
4. Semi-organic fertilizer (organic compound fertilizer). A fertilizer made by mixing or combining organic and inorganic substances. After the harmless treatment of the poultry manure, an appropriate amount of fertilizers such as zinc, manganese, boron, molybdenum and other trace elements are added.
5. Inorganic (mineral) fertilizer. Minerals are made of fertilizers in the form of inorganic salts by physical or chemical industry. Mineral potassium fertilizer and potassium sulfate; mineral phosphate fertilizer (phosphorus ore powder); calcined phosphate (calcium magnesium phosphate fertilizer, defluorinated phosphate fertilizer); limestone: limited to use in acidic soil; powdered sulfur fertilizer: limited to alkaline soil use.
6, foliar fertilizer. It refers to fertilizer fertilizers that are sprayed on plant leaves and can be absorbed and utilized by them. They must not contain chemically synthesized growth regulators. Trace element fertilizer is a fertilizer formulated mainly from trace elements such as cu, fe, mn, zn, b, mo and beneficial elements. The plant growth auxiliary fertilizer is a fertilizer prepared by using natural organic fertilizer extract or fermenting liquid for inoculating beneficial fungi with some humic acid, alginic acid, amino acid, vitamins and sugar.
3. Other fertilizers.
1. Includes foods without synthetic additives and organic by-products from the textile industry.
2. Includes fish residue without preservatives, beef wool waste, bone powder, amino acid residue, bone glue residue, etc.
