Yoshio Arai founded Arai Seisakusho LTD in Taito-ku, Tokyo Japan in 1951.In 1956 The establishment of ARS rubber seal. Yoshio Arai, President of his founded company Arai Seisakusho.Arai is registered as ARS the corporate mark and rubber seal as the product name.in 1999 ARS received ISO9001.Head office moved to Tsukuba, Ibaraki, Japan in 2009.in 2015 ARS received ISO/TS16949.

Features

• ARS Oil seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape.
• They also stop harmful contaminants from entering machinery.
• ARS Oil seals are lightweight, compact and provide stable sealing, so these are used in a wide range of machineries such as cars, motorcycles, construction/agricultural/industrial machineries and so on.

Benefits

• SQ type seals are benefical For Separation of oil and water of outboard motors.it also used for Crankshaft for two-stroke engine.As well as also used for Separation of engine oil and gear oil.
• SP types are used for the Shaft seal for the pump ,And Converter hydraulic clutch and so on.
• SID type seals For the place where shaft insertion is performed after installing oil seal such as mission, differential gears
• SDD4 type Seal of exposed parts such as motorcycle and front hub of automobiles, water seal for domestic appliances such as washing machine, mixer, disposer and so on.
• DD type Mainly to prevent invasion of dust and muddy water from the outside.It can seal the lubrication grease.
• M type Dedicated seal for mud etc.Since friction torque is large, it can not be used other than low speed rotation.
• OV type is installed in the O-ring groove of a piston etc. One-way pressure seal.Medium pressure with small sliding resistance.
• U type seals Packing for reciprocating high hydraulic pressure.And a sliding resistance is small in a groove of a piston or the like.

To realize this dream, Koyo Seiko and Toyoda Machinery merged in 2006 to form JTEKT. In response to the increasing sophistication and diversification of society’s needs, such as the realization of a decarbonized society, the automation of production equipment, and the electrification of automobiles, which have been a hot topic recently, as well as external environmental issues such as the new coronavirus infection and stagnation in the supply of semiconductors. In the midst of this, the company began searching for ways to achieve further sustainable growth. This is the start of “JTEKT Reborn

Features

• JTEKT’s koyo oil seals are lightweight, compact, and resource-saving, and their optimal lip structure provides excellent sealing performance.
• The rubber material has high self-lubricating properties, resulting in low heat generation and long life.
• O-rings exhibit high sealing performance against various gases and chemicals, including water, oil, and air.

Benefits

• The lubrication within the Koyo seal ensures that the seal lip does not come into contact with the rotary shaft, eliminating the risk of burning or wear.
• Koyo Oil seals possess a small and lightweight design, which belies their strong endurance capabilities.
• Even under harsh conditions or extreme temperatures, these durable components will maintain their seal.
• Easy to handle and assemble, koyo oil seals only take a matter of minutes to replace as technicians do not have to take a machine apart.
• Standard lip Koyo seals are best for applications within dry environments, or those lacking lubrication. Oil seals can act as an alternative with increased functionality.

The Company was originally the mechanical seal division of NOK Corporation, which was spun off on October 1, 1964. The corporate name became Eagle Industry Co., Ltd. in 1978.EKK sealing and control solution provider with a rich history and extensive experience. EKK is continuously improving our technology and diversifying our business activities to effectively respond to the evolving, sophisticated needs of our customers.

Features

• A stationary outside seal employing a rubber diaphragm. Achieves superb followability and corrosion resistance
• Eccentricity and shaft elongation/displacement absorbed by the universal rubber diaphragm
• Can be adopted under positive pressure or under back pressure
• seal rings are made of an extremely hard, wear-resistant and corrosion-resistant material. The rubber component presses the seal ring’s sliding surfaces and also serves as a seal.

Benefits

• Silicon carbide (characterized by superb wear resistance) used as the sliding material to ensure good performance for sealed liquids containing large amounts of solids.
• The benefits of floating seals include crawler rollers, travel drives and idlers of construction and agricultural machinery, and also for conveyors, mixers and various digging machines. In other words, they are used widely in relatively low-speed applications exposed to foreign matter.
• Titanium/Silicon carbide structure for special conditions.
