Angular Contact Ball Bearing

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. 

Deep Groove Ball Bearing

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:

  • Shielded / Sealed
  • Types with Locating Snap
  • Extra-Small and Miniature Bearings
  • Maximum Type Bearings
  • Double Row Bearings

For more information, please head over to the Koyo UK website. 

Cylindrical Roller 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. 

Spherical Roller Bearing

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 Bearing

Koyo offers tapered roller bearings in single and double row configurations and in both metric and imperial sizes. They consist of an inner ring (cone), an outer ring (cone), a cage and rollers which are profiled to ensure an even distribution of the load. 

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 Bearing

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:

  • Manual and Automatic Transmissions
  • Steering Columns
  • Drivetrain Components
  • Power Transmissions
  • Power Tools
  • Marine Applications
  • Mechanical Pumps
  • Consumer Products
  • Industrial Machinery

Ball Bearing Unit

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. 

Automotive Bearings

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:

  • Automobile Engines
  • Steering Systems

Bearings for the Rail Transport Sector

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. 

Bearings for Wind Turbines

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.
