TN Corporation is a full program manufacturer with production range totalling some 95,000 product items and variations. These encompass miniature precision ball bearings of 0.5mm bore size, right through to spherical roller bearings of 1,800mm shaft size. Applications are as diverse as large airliner turbofan jet engines to CT diagnostic scanning machines.
NTN further enhance the capability of their ball and roller bearing range by offering the NTN ‘Long Life’ series of bearing, featuring unique heat treatment processes, new alloys and chemical modifications, to achieve longer service life under adverse operating conditions.Since their foundation in 1918, NTN Corporation have grown to become a truly global organization, producing quality bearing and precision products in Japan, USA, Germany, France, Canada, China, Thailand, India and Taiwan.
IKO Needle Roller Bearings are rotational motion bearings in which a thin needle-shaped roller is incorporated into a rolling element. They have a low cross-section height and high load capacity compared with ball bearings. Being small, needle roller bearings contribute to reducing overall machine size, and are thus widely used in various applications such as automobiles, motorcycles, printing presses, industrial robots and construction equipment.
IKO Shell Type Needle Roller Bearings
IKO Shell Type Needle Roller Bearings are light weight bearings with large load ratings. They employ a shell type outer ring made from a thin special steel plate which is accurately drawn, carburized and quenched, thus providing the lowest sectional height among the needle roller bearings. There are two types of bearings available in this series; the caged type and the full complement type. The appropriate type can be selected according to the operating conditions. The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings. It is useful for applications at high-speed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavy-load applications at low-speed rotation. Since these bearings are press-fitted into the housing, no fixtures for axial positioning are needed. They are ideal for use in mass-produced articles that require economy, and have a wide variety of
IKO Needle Roller Cages
IKO Needle Roller Cages for General Usage are bearings which display excellent rotational performance. Needle rollers with extremely small dimensional variations in diameter are incorporated and retained in their specially shaped cages with high rigidity and accuracy, which precisely guide the needle rollers. When combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces, Needle Roller Cages for General Usage are particularly useful in small spaces. In addition, since they are lightweight and have high rigidity as well as a large lubricant holding capacity, they can withstand severe operating conditions such as high speed rotation and shock load, and they are used in a wide range of applications.
IKO Machined Type Needle Roller Bearings
IKO Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric series and inch series, both of which have the caged type and the full complement type. It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.

RBC produces an extensive heavy duty needle roller bearing product line from 1 inch outer ring diameter to 12 ¼ inch outer ring diameter. RBC has the capability to manufacture special designs up to a 39 inch outer diameter.
The RBC SJ series of Pitchlign® heavy duty needle roller bearings are supplied in standard envelopes in both sealed and unsealed configurations. There are eight possible seal configurations. The seals can include double or single seal with the seal lip turned inward or outward. The seal can be mounted in the radius end of the ring or the chamfered end of the ring for optimum mounting variations.
RBC’s patented TJ TandemRoller® heavy duty needle roller bearings increase the capacity of the standard Pitchlign® SJ series from 10% to 40% while maintaining the standard SJ envelope dimensions. The TJ design gives the heavy duty needle roller bearing 37% to 200% greater life over a standard single pocket bearing. These bearings are also available in sealed and unsealed configurations.
RBC heavy duty needle roller bearings present a wide variety of designs. The TJ Tandem Roller® and Pitchlign SJ Series heavy duty needle roller bearings are offered in a double-row design. The TJ and SJ roller bearings can also be matched with an inner ring or run directly on a shaft. RBC inner rings can be used separately or as an inner race for complimentary SJ or TJ roller bearings. The inner rings range are through hardened and precision ground.
The RBC SJ and TJ heavy duty needle roller bearing designs are easy to install and are especially beneficial in compact designs because of their high load capacity and small sectional height. The caged rollers allow for the RBC heavy duty needle roller bearings to be used in high speed applications.

Among the machine components responsible for yarn quality, top rollers and bottom rollers are by far the most important. Precise concentricity guarantees high yarn quality (evenness and strength).
Bottom roller bearings UL are used in ring spinning machines and roving frames as well as airjet spinning machines. As top-quality needle bearings they decisively contribute to spinning quality and operational safety under conditions of high load and speedTexparts® Bearings CR 2, ZL 11, ZL 17 and the DR Series
The Texparts® Bearing Units CR 2, ZL 11, ZL 17 and the DR Series are especially designed to meet the particular conditions for assembly and all other requirements of winding machines.
