Usage examples

Steel equipment
Steel equipment includes various equipment from the upstream process to the downstream process such as the steelmaking process, rolling process, and arranging process, starting from the raw material yard, and all kinds of bearings are used in each equipment.

Papermaking machine
In recent years, in the paper industry, the speed and width of paper machines have been increasing in order to improve productivity.

Semiconductor
Technological innovations in the fields of semiconductors, flat panel displays (FPDs), solar batteries and mobile phones have made remarkable progress.

Gear device (Gearbox)
Gear equipment is used in a very wide range of industrial fields.

Pump & Compressor
Pumps are used in all industries around the world, including petrochemicals, papermaking, irrigation and food.

Motorcycle
Although there are differences depending on the vehicle model and structural differences, 1 motorcycle usually has 20 to 30 bearings built-in.

Mining machine / construction machine
Mining and construction machinery can be used at mining sites far from human activities, such as mountainous areas and desert areas, and sometimes 2,000 m underground.

Wind turbine generator
Wind power is rapidly becoming widespread around the world as a clean energy source that does not generate carbon dioxide, which causes global warming.

Machine tool
The manufacturer develops and supplies bearings, ball screws, linear guides, and spindles, which are the elemental parts required for machine tools.

Industrial motor
Motors used as a power source in all industries.

Injection molding machine
In order to produce high-precision plastic products, the electrification of injection molding machines is progressing.

Product features details

Angular ball bearings have a contact angle, so they can support radial loads and large axial loads in 1 direction at the same time. Usually, angular ball bearings are combined, but it is also possible.

Features of single-row and double-row angular ball bearings

Single Row Angular Ball Bearing (Punching retainer & copper alloy machined retainer)
This bearing has a contact angle, making it ideal for receiving unidirectional axial or combined loads
Axial component force is generated when a radial load is applied due to the structure, so use 2 bearings facing each other or use them as a combination of 2 or more bearings
Single-row angular ball bearings can increase the rigidity of the bearing by applying preload, so they are ideal for applications such as spindles of machine tools that require shaft rotation accuracy

Combined Angular Contact Ball Bearing

Double-Row Angular Ball Bearing
A structure in which single-row angular ball bearings are combined on the bottom and inner and outer rings are integrated
Can be used as a fixed-side bearing that can load axial loads in both directions and has a load capacity against moment loads
It is a pressed retainer

4-point contact ball bearing
The inner ring is separated into 2, and one bearing can receive axial load in both directions
With a contact angle of 35°, it is ideal for
receiving a pure axial load with a large axial load capacity or a combined load with a large axial load
Uses a copper alloy machined retainer

About the type and features of combination bearings

Model	Features
Bottom combination type DB (Example) 7208ADB	Since the action point distance ao that can receive radial load and axial load in both directions is large, it is suitable when moment load acts
Front combination type DF (Example) 7208BDF	Since the distance of action point is small compared to the bottom assembly that can receive radial load and axial load in both directions, the load capacity for moment load is inferior
Parallel combination type DT (Example) 7208ADT	Since the axial load is received by 2 bearings that can receive the radial load and the axial load in 1 direction, it is used when the load in 1 direction is large
