| Suffix/Prefix | Manufacturer | Description | Example | Refers to |
|---|---|---|---|---|
| GL, /GL | NACHI | Light preload. | 7006ACYU/ GL | Angular contact ball bearings, Ball screw Support bearing |
| GE, /GE | NACHI | Extra-light prelaod. | 7205CDU/ GE P4 | Angular contact ball bearings, Ball screw Support bearing |
| GH, /GH | NACHI | Heavy preload. | 7905ACYU/ GH P4 | Angular contact ball bearings, Ball screw Support bearing |
| NNU | NACHI | A large number of rollers (cylindrical) for high rigidity. Tapered bore allows adjustment of the internal clearance. Oil groove and oil hole in the center of the outer ring width are also available. | NNU 4920 W33KMY | Cylindrical roller bearing |
| NN | NACHI | A large number of rollers (cylindrical) for high rigidity. Tapered bore allows adjustment of the internal clearance. Oil groove and oil hole in the center of the outer ring width are also available. | NN 3013M2KC9NAP4 | Cylindrical roller bearing |
| TBH | NACHI | The contact angle of this type is smaller than that of the previous TAD Series (double-direction thrust angular contact ball bearings), for less gyro-moment induced ball sliding and lower temperature. Can be used to replace TAD Series bearings. Contact angle α=40. | 90 TBH 10TDBP4 | Single row Angular contact ball bearings |
| TAH | NACHI | The contact angle of this type is smaller than that of the previous TAD Series (double-direction thrust angular contact ball иearings), for less gyro-moment induced ball sliding and lower temperature. Can be used to replace TAD series bearings. Contact angle α=30. | 120 TAH 10TDB/GMP4 | Single row Angular contact ball bearings |
| H | NACHI | Adapter sleeve. | H 208 | |
| AH | NACHI | Withdrawal sleeve. | AH 3126 | |
| BNH | NACHI | Since ball slipping is reduced by the gyro-moment at high-speeds, the ball diameter of this type of bearing is smaller than that of a standard angular contact ball bearing. This type of bearing is dimensionally interchangeable with the 7000 series, and can be used for their replacement. Contact angle α=15. | BNH 014TU/GL P4 | Single row Angular contact ball bearings |
