| Model: |
| Angular contact bearings support thrust loads or combinations of radial and thrust loading. They cannot accept radial loads only --a thrust load of sufficient magnitude must be present. An individual angular contact bearing can be thrust-loaded in only one direction; this load may be a working load or a preload.

|
| Model: |
| The main purpose for applying a preload to machine tool spindle bearings is to increase their rigidity, improve running accuracy, and prevent sliding of the rolling elements at high speed. Usually a preload is applied to bearings by using two or more in combination, such as angular contact ball bearings or tapered roller bearings. Cylindrical roller bearings can be preloaded by making the radial internal clearance slightly negative. |

| LFR5208-40KDD |
|
| Model: |
| Feature
With high rotary speed and precision, low noise and oscillation, they could withstand radial and axial load simultaneously. There is a contact angle between rings and balls, and they are available in 15, 25, 30 and 40 degree angles. The larger the contact angle is, the higher the radial load capacity is; the smaller the contact angle is, the more positive for high-speed operation. Furthermore, the self-alignment capacity of angular contact ball bearings is very small.
