IKO's Extended Life Specification Machined Type Needle Roller Bearings are treated with a newly developed special heat treatment that enhances the bearing's surface hardness and toughness, and suppresses the generation and growth of damage on the surface. Significant life extension can be achieved under high load or under the condition of lubrication contaminated with foreign substances. In a life comparison test, IKO's special heat treated Extended Life Series products lasted 5 times longer than standard heattreated products.

IKO Machined Type Needle Roller Bearings are bearings with a low cross sectional height and large load ratings. The outer ring has stable, high rigidity and can be used even for light alloy housings. These bearings are available in metric series and inch series, both of which include a caged type and full complement type. They are suitable for a wide range of conditions including heavy load with either highspeed or lowspeed rotation. In addition, bearings are available with or without an inner ring. The type without an inner ring uses a shaft as the raceway surface, making the design compact.

Our CLube technology maintains the lubrication performance for an extended period of time, reducing lubrication schedules and the time it takes to manage them.

The AntiCreep Cage Crossed Roller Way Unit prevents cage creep by using a rack and pinion mechanism in the crossed roller way that is mounted to a groundfinished rigid table and bed. The builtin rack and pinion mechanism is the perfect solution for cage creep issues. It provides reliable operation in various situations where a crossed roller way would be difficult to use, including applications on a vertical axis. No correction for cage creep is necessary, even under high velocity or long term operation. Interchangeable Mounting Dimensions Since the rack is placed inside the way, it maintains the same outside dimensions and offers complete mounting compatibility with the conventional crossed roller way unit; making it easy to replace the conventional type crossed roller way units in machines and equipment, as well as using it in new designs. UltraHigh Precision and Smooth Motion A combination of a precisely finished raceway surface and a nonrecirculating type linear motion

IKO Thrust Bearings consist of precisely machined cages and rollers. They have high rigidity and high load capacity and can be used in small spaces. Thrust Needle Roller Bearings use needle rollers, while Thrust Roller Bearings use cylindrical rollers. Various types of raceway rings are available, and can be selected according to the operating conditions. When the bearing mounting surface of a machine is heattreated and finished by grinding, Thrust Bearings can be used without raceway rings, making the machine more compact. They are best suited for applications where high accuracy is required at high speeds and under fluctuating heavy loads, such as the drive mechanisms for automobiles, machine tools, and highpressure pumps.

IKO Needle Roller Cages for General Usage are bearings that provide excellent rotational performance. Their specially shaped cages, with high rigidity and accuracy, precisely guide the needle rollers. Since needle rollers with extremely small dimensional variations in diameter are incorporated and retained in this needle roller cage, they utilize the machining accuracy of the way and are useful in small spaces when combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces. 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 loads, and they are used in a wide range of applications.
