With 50 years of experience, IKO focuses on high-quality needle roller bearings, linear motion rolling guides, precision tabletops, and mechanical parts. The company’s products are rolling linear motion guides. IKO adopts a linear motion rolling guide, which reduces the linear motion friction of the mechanical positioning mechanism.
For example, our linear guides and linear roller guide systems, as well as shaft guidance systems based on ball splines. Needle Bearings: The needle roller bearings produced by our company have low cross-section height and high load-bearing capacity and can be rotated. Thin needle rollers are integrated into the rolling elements. Because these bearings are small, they help reduce the overall size of the machine. Precise positioning table Our company’s direct-drive precision positioning table combines precision processing technology with electronic devices, and a ball screw or motor is embedded between the bed and the sliding table.

IKO Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing. Caged Needle Roller Bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings. They are compact and very economical, and can be subjected to radial loads and axial loads simultaneously. They are widely used for machine tools, textile machinery, and industrial machinery.
PLAIN BEARINGS
Our plain bearings ensure articulating systems perform their best and support heavy and complex loads. Our lineup includes many styles of spherical bushings, as well as rod ends to address misalignment and other angular motion challenges. These units are ideal for a wide range of machines and equipment in industries like general industrial, automotive, construction, agriculture and packaging.
Spherical Bushings
SB SBB GE
IKO Spherical Bushings are compact self-aligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bi-directional axial load at the same time. There are many models of Spherical Bushings, but they are basically divided into steel-on-steel types and maintenance-free types according to the kind of sliding surfaces. Steel-on-steel Spherical Bushings have inner and outer rings of high-carbon chromium bearing steel, of which sliding surfaces are phosphate-treated and then dry-coated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery. Maintenance-free Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced with copper alloy meshes on the sliding surface, and a spherical inner ring of which sliding surface has a hard chromium plating. Creep deformation due to compressive load is small, and wear resistance is superior. Thus, they are maintenance-free and can be used for extended periods of time without re-lubrication. They are especially suitable in cases where fixed directional loads are applied and are used mainly in food processing machines and construction machinery and in other applications in which the use of oil is undesirable or lubrication is not possible.
PILLOBALLS

IKO PILLOBALLs are compact self-aligning spherical bushings which can support a large radial load and a bi-directional axial load at the same time. These bearings are available in insert type, die-cast type and lubrication-free type depending on the type of sliding surface. In the insert type, a spherical inner ring makes contact with a special copper alloy bushing with superior run-in properties. In the die-cast type, a spherical inner ring makes direct contact with the bore surface of the body of special zinc die-cast alloy. In the maintenance-free type, a spherical inner ring makes contact with a special self-lubricating PTFE liner. Thus, a smooth rotational and oscillatory motion can be achieved with superior anti-wear and load properties in each type. PILLOBALL Rod Ends have either a female thread in the body or a male thread on the body, so they can be easily assembled onto machines. They are used in control and link mechanisms in machine tools, textile machines, packaging machines, etc. The maintenance-free type is especially suitable for loading in one direction and is the best choice for machines in which oil must be avoided such as food processing machines, or machines which cannot be re-lubricated.
L-Balls
LHS LHSA
IKO L-Balls are self-aligning Spherical Bushings consisting of a special zinc die-cast alloy body and a studded ball which has its axis at right angles to the body. They can perform tilting movement, oscillating movement and rotation with low torque, and transmit power smoothly due to uniform clearance between the sliding surfaces. Their superior wear resistance assures stable accuracy for long periods of time, and maintenance is simple. They are very economical bearings. For these reasons, they are widely used in link mechanisms in automobiles, constructio
Super Flexible Nozzles
SNA SNM SNPT
The IKO Super Flexible Nozzle is a compact nozzle used on machine tools to supply and spray cutting oil exactly at a specified location. Since the angle of the nozzle can be easily changed, the oil supply can be concentrated on the working area, and cooling and lubrication can be performed effectively. As a result, cutting resistance is reduced and superior finish is obtained, achieving high machining accuracy. The tool life can also be extended, which can result in cost savings. The Super Flexible Nozzle can be used at the spindle end of machining centers and at the tool holder of an NC lathe.
