[INQ. NO. 2211M38] Oilless Bearing manufactured and supplied by HANKOOK MATERIAL Co., Ltd. is a bearing that can promote improvement of a machine’s performance, reduction of fueling manpower and cost, and productivity improvement by realizing oilless conversion on parts where fueling is impossible or ineffective due to high load, low speed, low temperature, corrosive atmosphere, foreign substance inflow, impact load, vibration, and structure.


The applicable materials and shapes of the company’s Oilless Bearing vary depending on the conditions of use, from metal, copper, Teflon, and ceramics to high-functional plastic.

Necessity of oilless bearing
It has various materials and shapes, so it can be used instead of balls and roller bearings for parts where they cannot be used.


It can prevent a decline in productivity caused by the shutdown of a machine when fueling.

Advantages of dry sump lubrication (use of solid lubricants)
It can be used at low and high temperatures. It can also be used in corrosive atmospheres. It is perfect for slow motion of high loads, reciprocating motion, impact load, angle shaking motion, and discontinuous multiple stop motion. It can be used 100% oilless.


HANKOOK MATERIAL Co., Ltd. is developing and producing competitive products by constantly investing and developing, so their products can be supplied and applied not only to domestic auto, industrial machinery, and machine tool industries, but also throughout industrial machines, heavy equipment, and molds in Asia and Europe.
The CEO of this company emphasized, “We will keep doing our best to be a company developing together with our customers by providing high-quality systems through constant R&D and investment.”

https://korean-machinery.com///inquiry

[INQ. NO. 2208M02] SAMICK Precision Ind. Co., Ltd., as an enterprise that manufactures factory automation-related products as its specialty, produces and sells linear motion bearings and linear guide, based on its technical development.


Also, the company was selected for its worldwide first-class goods, raising the brand of the Republic of Korea.


For more than 30 years, SAMICK Precision Ind. has developed trusted and intensive business around the world and been selected for its world top class products by Korea.

Linear Bushings
Its most basic products of linear motion bearings are mainly used in devices with low load. They are manufactured in a variety of shapes & sizes including standard, flange, open type, adjustable type and super ball — and are used in factory automation equipment, general machinery, machine tools, packaging machines, food machines, measuring machines, and for loading, unloading, and transferring.


This product is a linear motion system that performs infinite linear motion in combination with a cylindrical LM shaft. Since the load ball and the LM shaft are in point contact, the allowable load is small but designed with minimal frictional resistance. The load ball is aligned in the LM shaft direction by an integrated retainer. Linear bushings are mainly used in precision equipment such as computers and peripherals, various measuring instruments, automatic recording devices, digital 3D measuring machines, multi-axis drilling machines, punching presses, tool grinding machines, automatic gas cutters, printing machines, card sorting machines, food packaging machines, etc. They are widely used in linear motion guides for industrial machines, exercise equipment, and wood machines.

Guide Masters
SAMICK’s guide master offers 4H (High load capacity, High accuracy, High Speed, and High rigidity) by needle rollers on polygonal guide comparing to the Guide with balls. SAMICK Guide Master guarantees longer life of die sets and the precise motion required for equipment by its high stiffness and straightness and smooth motion.


This product is a type of linear motion bearing, and by arranging needles in a polygonal structure, high rigidity that cannot be obtained from a ball guide is realized. It is a product with high precision, high speed performance, and long life.


With high rigidity, straightness and smooth movement, it is possible to maintain stable precision of the die set and precision upper and lower guides for a long period of time; and it is a product with improved durability against high speed and intermittent operation and vibration.


Guide masters are applied to the industry of Semiconductor, liquid crystal-related mounting device and inspection device, lifting/slide stage, robot arm, press machine, conveying device, guide for press unit for precision machines, punching molds for thick material, control function for positioning, jig, etc.


It is a guide that responds to the need for high rigidity, high speed, and straightness.

https://korean-machinery.com///inquiry[INQ. NO. 1803M07] Jalman Precision has since 1974 been manufactured state-of-the-art products such as needle roller bearings, rod ends, spherical plains, ball joints, LM stroke by using self-developed technology. The company continues to produce rare kinds of bearings with competitiveness in terms of price, quality, design, durability, etc. To meet the demanding requirements from the valued clients of global markets, the firm is fully equipped with such arrangements as upgraded facilities and knowhow.
The maker’s cam followers are main players that lead the company’s overseas drive. They can be effectively applied into static loads and heavy loads at low and middle high speed.The most elements such as shafts, rollers, needles and thrust washers are made of carbon chromium bearing steel.
The NA 49 and NKI series are basic bearings assembled with outer ring, cage with needle rollers and separable inner ring. These bearings can have heavy loads because the friction figure is much higher than ball bearings and can be subjected to high speed rotations depending on the loads because a cage assembly prevent from friction of each needle rollers.
Furthermore, JMC bearings are suitable for many kinds of machines such as automatic machinery, cam working assembly, specialized machinery, transmission for vehicle, printing machinery, air-pump, electric clutch, hydraulic machine, etc.

The group of engineers from Jalman Precision specialize in bearings providing customers with solutions based on selfdeveloped systems designed for quality improvement. They discover new items, minimize defective products, and monitor in real time quality-abnormalities in order to satisfy the ever-varying and exclusive demands of customers.
The company provides services via a network in around 30 countries across the world, playing a key role in the development of the machinery industry through environmentally friendly management and corporate philanthropic activities.
Park Kyung-yoon, CEO of Jalman Precision, explains, “Although our sales volume is still small, we are exporting to around 30 countries including those in Europe, the Middle East, Australasia, and Asia, as well as North, Central, and South America and successfully positioning ourselves in the global market. We put our heart and soul into each product we produce.”

Select Products Recommended by KOITA

[INQ. NO. 1412M19] Established in 1998, Jaewoo Housing Tech specializes in manufacturing industrial machinery including bearing housings, cases, etc. based on the world’s top-level technologies. Those products are exported to European and American markets, continuously increasing the brand awareness of the company in the global market.

Bearing-housings https://korean-machinery.com///inquiry Long years of its aggressive moves and accomplishments are fruits under the philosophy of “First releasing products than foreign competitors in China, Japan, and Europe.” Consequently, such an approach partially led to the localization of the advanced technologies leading overseas markets.

Jaewoo Housing Tech, with innovative colors and design, has been energetic in pioneering new overseas markets. The maker focused not only on exterior design, but also on functionality of products. With its own patented technologies, the maker adds heat treatment by penetrating resin-kinds of paints into steel. When compared to the existing products, the rate of corrosion resistance is elevated by more than 60 percent and so the occurrence of the paint removal is fundamentally prevented. All of its bearing housings are now under the status to swiftly respond to any urgent orders on the spots.

And after development of new models of products, release time can be also promised within shorter periods than any competitors. Potential customer companies can enjoy the decreased opportunity and the first cost together.
