7）Bearing units (e.g., pillow blocks)

Bearing units (e.g., pillow blocks) Description Brand
ベアリングユニット（ピローブロック等） A bearing unit consists of a sealed radial ball bearing in combination with a bearing housing, the substance of which can be selected from a variety of materials, such as cast iron and sheet steel. The contact surfaces of the bearing and housing are spherical and equipped with aligning properties. Bearing units in a broad range of variations are available with a wide range of housing materials. FYH、etc

8）Custom-made special bearings

Custom-made special bearings Description Brand

9）Others

Others Description Brand
その他 Resin-made bearings as well as other types of bearings responding to a variety of environmental requirements (e.g., heat-resistant, chemical-resistant, and water-resistant requirements) are available. Oilless bushings are available as well for product downsizing, performance improvement, long-life extension, and laborsaving purposes. DAIDO、ELGES、MATEX、MTR、NDC、OILES、ORIGIN、SANKYO、TOK、UKB、etc

10）Direct-drive applications

Direct-drive applications Description Brand
直動関係 Roller bearings, each of which incorporates a roller and balls as rolling elements, are available. Roller bearings used for equipment will make it possible to reduce the size and weight of the equipment while maintaining stable precision for a long period, thus greatly improving the reliability of the equipment. Roller bearings are widely used for industrial applications, such as machine tools, industrial robots, and metal processing machines. EASE、NSK、THK、TSUBAKI、etc

11）Swing bearings

Swing bearings Description
旋回ベアリング A single bearing can receive a thrust load, radial load, and the moment of force simultaneously, and either the outer ring or inner ring incorporates a gear, thus making it possible to simplify the structure of the rotating part. Both the outer ring and inner ring incorporate a through or tap hole each used to mount the bearing, which allows ease of mounting and dismounting.

How do you distinguish size of bearings easily?

Last two figures of a model number of a general bearing mean its internal diameter in accordance with a rule except that of miniature ball bearings(internal diameter is under 10mm) and tapered bore.
00 means 10mm, 01 means 12mm, 02 means 15mm, 03 means 17mm, 04 means 20mm.
When last two figures of a model's number are 04 or over, the number which the last two figures are multiplied by 5 mean the model's internal diameter.

For example,
6204→04(model's last two figures of number）×5＝20mm、6205→05（model's last two figures）×5＝25mm、・・・6210→10(model's last two figures）×5＝50mm.
Even if types of a bearing are different from each other, their internal diameter is the same length when last two figures of a number of the models are the same number.

For example,
6206、7006、1206、5306、NU206、30306、22206、51106、UCP206・・・
Last two figures of the above numbers of models are 06 and their internal diameters are 30mm(= 06 × 5).
