NSK

Kastel Karlovo JSC is an authorized distributor of NSK brand bearings NSK Ltd. – Nippon Seikō Kabushiki-gaisha. , Japanese Precision Company.
http://www.nsk.com/

NSK is one of the world’s leading manufacturers of bearings, linear technologies and steering systems. The company offers almost all types of bearings, including deep groove ball bearings, spherical and cylindrical roller and super precision bearings

NSK was founded in 1916 and produced the first ball bearings in Japan. Today, NSK’s global network covers America, Europe, Asia and Japan. NSK operates 59 locations in Japan and a total of 208 production sites, sales locations, representative offices, and technical service locations in 30 countries and regions around the world.
https://www.nsk.com/company/globalnetwork.html

NSK has made a vital contribution to the growth and advancement of the various industries that rely on machinery. As a comprehensive bearing manufacturer, NSK responds to needs in a wide variety of fields.
https://www.nsk.com/products/index.html

“Responsive” – expresses NSK’s ability to respond effectively to new opportunities and customer needs, while maintaining a sense of harmony with societies and the global environment. In particular, “responsive” embodies five types of concepts:

  • Sustainability
  • Smoothness
  • Perseverance and perseverance
  • Flexibility
  • Technologies

A surprisingly large number of bearings can be found all around us. Take automobiles, for example: there are 100 to 150 bearings in a typical car. Without bearings, the wheels would rattle, the transmission gear teeth wouldn’t be able to mesh, and the car wouldn’t run smoothly.
https://www.nsk.com/company/vision/bearings.html

Bearings are not used only in cars, but in all kinds of machinery such as:

  • trains
  • airplanes
  • washing machines
  • refrigerators
  • air conditioners
  • vacuum cleaners
  • photocopy machines
  • computers
  • satellites

Bearings enhance the functionality of machinery and help to save energy. Bearings do their work silently, in tough environments, hidden in machinery where we can’t see them. Nevertheless, bearings are crucial for the stable operation of machinery and for ensuring its top performance.

The word “bearing” incorporates the meaning of “to bear,” in the sense of “to support,” and “to carry a burden.” This refers to the fact that bearings support and carry the burden of revolving axles.
https://www.nsk.com/company/introduction/index.html

NSK bearings are used in over 200 000 different products. Bearings of different sizes are produced: from miniature bearings with an outer diameter of 2 mm, used in ultra-compact motors to bearings with an outer diameter of 6 meters used in giant machines for digging tunels. NSK produces bearings for dental machines that spin at high speeds up to 400,000 rpm. The bearings used in steel-production equipment are made for extremely harsh working conditions – they can be exposed to temperatures above 1000 °C and be subjected to repeated heating and cooling temperature fluctuations. Bearings used in wind turbines need to withstand a minimum of 20 years of usage without claim.

Kastel Karlovo JSC is a distributor of Saint-Gobain abrasives, France

Saint-Gobain Abrasives is the world's leading manufacturer of abrasives, it is the only international supplier that produces all three main types of abrasives - abrasives for grinding (with organic and ceramic joints), sand paper and diamond products.

As a distributor of Saint-Gobain for the territory of Bulgaria, Kastel Karlovo JSC offers Norton & Winter brand products.

Abrasives are used for surface treatment of different materials, by removing thin shavings, using technology that allows high-precision in achieving required dimensions and surface.

Chain slings are manufactured according to EN 818-2, safety class 4: 1. Their main advantage is the ability to shorten each shoulder by means of shortening hooks placed next to the main ring of the sling and thus are a preferred means of lifting loads of irregular shape. Chain slings can be made with up to 4 arms and a different element can be placed at each end of the sling - a ring, hook, shackle or other specialized grip.

Class 10 chain slings are made in accordance to the requirements of the world quality standards EN 818-4-2017. Class 10 chains, as well as the individual elements (hooks, rings, etc.) are blue. Class 10 chain slings have an increased load capacity by 25% (69 tons) compared to class 8 chain slings (55 tons) and they allow direct mounting of the elements without the use of additional connectors such as connecting links or shackles.

Steel wire rope slings are manufactured according to EN 13414-1 and are made of steel wire ropes with different construction - 6x19, 6x36, 6x37 with organic or metal core. They are made of both galvanized and non-galvanized ropes. Steel rope slings can have up to four separate arms.

Kastel Karlovo JSC manufactures crimped or woven eye slings up to diam 76mm with a load capacity of 70 tons. Per customer's request an additional element such as hook, link, shackle or another element can be placed at each arm of the sling. When placing an additional element, it is recommneded to use wire rope thimble in order to prevent the rope from breaking.

Round polyester slings are made of high quality polyester fibers wrapped in a protective cover. When using round slings, there is the lowest risk of injury to the load. Their main advantage is their flexibility, lightness and significantly smaller bandwidth compared to flat-eye slings. They also have a higher load capacity - up to 150 tons.

Polyester webbing slings are one of the most common products for lifting loads and are used in all industries due to their high load capacity. They are characterized by lightness, flexibility and long service life.

Different types of accessories such as links, hooks, shackles and other specialized grips can be attached to the arms of the polyester webbing slings. There are two types of polyester slings - eyeless, round polyester slings (load capacity up to 100 tons) and flat-eye polyester slings (load capacity up to 30 tons). They have a security ratio of 7: 1.

Webbing slings are resistant to aggressive environments and liquids, the operating temperature at which they can be used is from -40 to +100 degrees. The slings are color coded and are manufactured according to EN 1492-1. Each sling has a sewn certificate showing its length, workload, serial number and date of manufacture and is accompanied by a quality certificate, declaration of conformity and instructions for safe use.

Kastel Karlovo JSC manufactures crimped & woven eye wire slings, polyester slings, chain slings and round endless slings according to the established European norms. Per customer's request an additional element such as hook, link, shackle or another element can be placed at each arm of the sling. Each sling is accompanied by an information label where the product data is recorded (workload, length, serial number and date of manufacture) and a Declaration of conformity.

In order to meet clients' needs, Kastel Karlovo JSC together with its European partners invests in organizing joint trainings for their employees.
