nsk bearings
NSK produces all kinds of bearings, automotive components, linear guides, ball screws, mechatronic products and lubrication systems and distributes them around the world. SRG Bearings Ltd also offers associated services. It has more than 23,000 employees who form a worldwide technology network consisting of over 40 production plants. Every day, they manufacture approximately three million new bearings with the NSK brand.

     SRG Bearings Ltd invests more than €60 million in research and development each year. The Group has its own research and development centres on every continent. NSK’s products are considered to be extremely reliable, resistant, durable and energy-efficient.

     Bearings made by NSK are used in a wide range of industries. They can be found in machine tools, wind turbines, industrial and domestic pumps, compressors and much more. NSK’s product portfolio comprises everything from miniature bearings with a one-millimetre bore to bearings with a diameter of five metres.

      NSK linear guides (also caled linear bearings or guide rails) are designed for superior linear motion. NSK has designed different series of linear bearings to meet the diverse needs of the various industries we serve. For more specific applications, NSK offers special coatings, lubricants, accuracies and custom designs. Maintenance-free operation with K1™ Lubrication Units are available on most NSK linear bearings. 

     NSK has used its expertise in precision machining technology, refined through years of bearing manufacturing, to diversify into:

automotive products 
precision machinery and parts 
mechatronic products 

      Since the 1960s, NSK has been aggressively developing its overseas markets. At present, the company has 70 sales sites in 25 countries, and 37 production sites in 12 countries. NSK strives to enhance development capabilities, productivity, sales forces, and management abilities throughout its global network, aiming for further advancement of its motion and control technologies.

air bearings

                                 Air Bearings

 

           Basically, air bearings use a thin film of pressurized air to support a load, the same way the puck on an air hockey table "floats" on air. This type of bearing is called a "fluid film" bearing. Fluid film bearings have no solid-to-solid contact under typical running conditions; instead, a film of lubricating fluid (in our case pressurized air) forms a layer between the solid machine elements and serves to transfer forces from one to the other. To compare this with ball bearings, in ball bearings the balls are in constant contact with and form a solid bridge between the machine elements.

 

           Cylindrical air bearings often find use among frictionless rotating supports such as spindles.  Our expanding standard product line offers the UTT series universal turntables with nanometric rotational accuracy and remarkably high stiffness (see chart below).  Utilizing both cylindrical and thrust surfaces, these bearings provide load capacities up to 230 lbf.  Every UTT now features SAFELOCK(tm); a safe and effective way of restricting the rotor without loosing concentricity and parallelism with the stator.

 

            As part of our standard manufacturing process and immediately prior to shipment, each bearing is fully characterized for performance using our custom-designed testing equipment.  Automated data acquistion provides consistent, accurate and timely measurement of relevant parameters including: load capacity, flying height, flow rate, vacuum preload, temperature, humidity, inlet pressure, film pressure, barometric pressure, etc. Bearing surface sphericity can be measured using non-contact capacitance probe or laser based interferometric analysis.

 

            In addition to our product line of air bearings, we provide a wide range of sub-contract manufacturing including tools, gages, precision cams, special machines, and prototype or production parts. Our highly skilled technicians combine a profound understanding of precision engineering with the experience of many years; we satisfy and delight customers around the globe. For prompt, personal service, please let us know how we might contribute to your high-precision project.

 

            In an air bearing, the balls are replaced by a cushion of air. Perhaps one of the most familiar applications of an air bearing is a hovercraft. Large fans blow air underneath the hovercraft and the air is prevented from escaping by a flexible rubber 'skirt'. The high air pressure generated under the hovercraft is capable of supporting its weight and it therefore floats on this cushion of air. The large cushion of air not only acts to support its weight but also as a soft spring which allows it to float smoothly over the rough surfaces on land or in the water.

needle roller bearings

                                 Needle Roller Bearings

 

          A needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surface.

 

           Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact. The typical structure consists of an a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race(sometimes housing itself).

 

            Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.

 

            Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.

 

            Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each U joint) and often more if it is particularly long, or operates on steep slopes.

 

            Additional clarification of Needle Roller: According to "Marks' Standard Handbook for Mechanical Engineers", a Needle Bearing is a roller bearing with rollers whose length are at least four times their diameter.

 

             Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
