Koyo is one of the world’s leading bearing brands. It is a name that has become synonymous with quality engineering and innovative design. The Koyo range, produced by the JTEKT Corporation (a global bearing manufacturer), covers a wide variety of industrial applications, from automotive steering to power generation.
JTEKT Corporation stands at the very forefront of the bearing industry, and its market-leading brands are known and trusted the world over. It owns and operates eighteen bearing plants in seven countries, as well as six R&D Technical Engineering Centres across three continents. The Corporation’s product development capabilities are second to none.
The Koyo collection, available to customers in the UK and throughout Europe, ranges from super large bearings with outside diameters of seven metres right through to miniature bearings with inner diameters as little as one millimetre. We have solutions for many different industries and applications, including:

Koyo angular contact ball bearings are available in single or double row configurations. They are designed to offer exceptional accuracy and outstanding high-speed performance, and they are able to carry combined loads (both axial and radial).
Information on how these bearings function can be found on the Koyo website.
Koyo angular contact bearings are available in steel, stainless steel, plastic and ceramic hybrid. They can also be plated (commonly with cadmium or chrome).
Angular contact bearings may have various different types of seal or shielding for lubricant retention and protection against contamination. Please visit our website to find out more.
JTEKT produces a comprehensive range of deep groove ball bearings. A wide variety of sizes are available to cover most application requirements.
Deep groove ball bearings are the most popular of all rolling bearings. They are able to simultaneously support radial as well as a certain amount of axial load in both directions.
The Koyo range includes several different types of deep groove ball bearing:

Koyo cylindrical roller bearings are available in single, double or four row configurations. They feature a thrust collar, a parallel or tapered bore and lubrication holes and grooves.
Because the rollers and raceways are in linear contact, this type of bearing has a high radial load capacity. It also has a moderate thrust-load capacity.
Information on how these bearings function can be found on the Koyo website.
Most of our cylindrical roller bearings are made from alloy or low-carbon steels. However, we can also offer bearings made with high carbon, case- or through-hardened steel should your application demand it.
Cylindrical roller bearings have many applications, from mining and petroleum production through to power generation and transmission.
A spherical roller bearing is a type of self-aligning bearing with a large load capacity. This makes it suitable for low to medium speed applications that involve heavy or impact loading.
These bearings come with cylindrical or tapered bores and may be supplied with adapter assemblies and withdrawal sleeves.
Information on how they function can be found on the Koyo website.
In most cases, spherical roller bearings will be made of alloy steels or low-carbon steel, though we can also manufacture high-carbon, case- or through-hardened steel bearings if required.
Tapered roller bearings can be produced in
TDO (one double cup and two single row cones) and TDI (one double cone and two
single row cups) versions.
Tapered roller bearings are designed so
that the cups, cones and rollers have tapered surfaces whose apexes converge at
a common point on the bearing axis. This makes them suitable for applications
that involve heavy or impact loading.
Needle roller bearings are ideal for applications where a compact load-bearing solution is needed. They are able to handle high load and speed capacities yet have the smallest cross section of all roller bearing types.
The Koyo range includes a variety of premium quality needle roller bearings in both metric and imperial sizes. These are typically used in/for:

Koyo ball bearing units consist of a pre-lubricated and sealed ball bearing and a housing that can vary in size and shape.
These units are able to align themselves efficiently using the spherical fitting surface between the bearing and the housing, thus preventing overload caused by misalignment.
Koyo ball bearing units are highly accurate and offer excellent load resistance. They are available with or without a re-lubrication feature.
We offer a wide selection of bearings for the automotive industry. The Koyo range – which includes many different bearing types – covers virtually all automotive engineering applications.
The bearings we supply are used in/for:

This is an industry that demands levels of performance and reliability that only a leading bearing manufacturer like JTEKT can provide. Our Koyo range includes many high-performing, ultra-reliable bearings approved for use in aerospace and aviation applications. A combination of innovative technology, technical expertise and advanced manufacturing processes makes them trusted by aircraft manufacturers right across the globe.
Applications include:
Manufacturers of agricultural equipment require bearings that offer reliable operation under the toughest of conditions. As well as being dirt- and humidity-proof, they need to be able to withstand significant temperature changes, and they also need to handle varying load, speed and surrounding conditions.
Drawing upon decades of experience in this field, JTEKT has developed a series of bearings that can withstand the elements and ensure faultless operation in all environments.
Koyo bearings can be found in tractors, trailers, mowers, silage cutters, front loaders, cultivators, ploughs, balers, harvesters and hoes right across the world.
The construction industry underpins the world economy, and so the need for reliable and efficient machinery is critical. When faultless operation is required, manufacturers of construction equipment turn to Koyo bearings. This is because Koyo bearings are able to function reliably day in, day out, under some of the most demanding conditions.
JTEKT supplies high quality bearings to manufacturers right across the globe. Applications include planetary gear reducers, steering systems, pumps and driveshafts.
Koyo bearings are used in a huge range of electrical appliances, from power drills to washing machines.
The range consists of many lightweight, compact, durable and economical products ideal for power tools and consumer electronics.
JTEKT manufactures a large range of advanced bearings and associated products for the marine industry, a sector that demands high grade components capable of withstanding some of the toughest operating conditions.
Koyo marine-grade bearings are designed to offer reliable performance in various marine environments.
Our track record shows that just about any environmental challenge can be overcome with a creative engineering solution at an economical price.
Koyo bearings are used in various marine power head and drivetrain applications. Find out more by visiting Koyo UK online.
JTEKT bearings are also used in the medical and healthcare sector, primarily for the smooth and reliable operation of CT-scan devices. For these applications, Koyo EXSEV bearings offer an extremely effective solution. This is because they are designed to work in both corrosive and magnetic environments, as well as those that require maximum cleanliness. EXSEV bearings also operate reliably in vacuum conditions and in very high temperatures.

Railway vehicles tend to be put under a great deal of stress; they operate continuously for a long period of time, often in very harsh conditions. Any component used in their manufacture must therefore be safe, reliable and capable of fault-free operation under tough circumstances.
Koyo high precision bearings fulfil all of these requirements. That’s why they are used by rolling stock manufacturers the world over.
The reliability of Koyo bearings is best demonstrated by their use in the motor and transmission of the Shinkansen high-speed bullet train in Japan, which has one of the world’s best safety records.
JTEKT supplies bearings to the world’s top listed wind turbine manufacturers. Our products are used for the efficient and reliable operation of generators, gearboxes and main shafts.
Wind turbines are expected to run for around 20 years with only a minimal amount of maintenance (due to the difficulties involved in accessing them). Therefore, any component used in their manufacture must be able to perform reliably for an extended period of time.
JTEKT has designed a range of bearings to meet this demand. Visit Koyo UK online to find out more.
