Metals, alloys and composite powders commonly used in thermal
spray hardfacing technology and coating service. These unique powders are
instantly heated by thermal spraying (welding) methods such as high temperature
flame or explosive flame, and are sprayed and deposited on the cold or hot
workpiece surface with high-speed heat flow in a molten or semi-melted state to
form a surface Reinforcing layer, in order to improve the wear resistance,
corrosion resistance, heat resistance, oxidation resistance or repair of
external dimensions of the workpiece surface. XTC produces WC, CrC, Oxide
Ceramic, Boride Powder, Metal Alloy Powder, Pure Metal and Spray Wire, etc.
product. For HVOF/HVAF/plasma/Flame spray coating and applications. Meet the
wear and corrosion resistance requirements of different surfaces.
WC, CrC oxide ceramic powder and boride
products are excellent in wear resistance and high temperature corrosion
resistance. Taking WC products as an example, the hardness can reach
HV1300-1500, and the temperature of CrC products can reach 800 degrees Celsius.
Metal alloy powder, Pure Metal and Spray
Wire products have more applications in glass mold, steel and machinery
industries. And XTC products are now become more and more popular in Metal
spray coating and thermal spray coating industry.

1. Cylindrical roller bearings are available in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.
2. In cylindrical roller bearings, the rollers are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimises rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.
3. In a single row cylindrical roller bearing, the rollers are always guided between the integral "open flanges" on one of the rings. These "open flanges" combined with the specially designed and surface treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature.
4. The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings.
5. Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds. They are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs.
6. Applications:
Electric motor, automotive, industrial transmission, double-row cylindrical roller bearings are greatly used for the spindles of machine tools
7. Models available:
1) NU, NJ, NUP and N design, single row cylindrical roller bearings, caged
2) NNU and NN design, double row cylindrical roller bearings, caged
3) Multi-row cylindrical roller bearings, caged.
4) NCF and NJG design, single row full complement cylindrical roller bearings
5) NNF desgin, double row full complement cylindrical roller bearings
6) Multi-row full complement cylindrical roller bearings, with four or eight rows of rollers.
