NSK Ltd. 日本精工 (NSK) 高精度斜角滾珠軸承 (萬用組合/單體型) 7900A5TSULP4

Features

• Single row Angular Contact Ball Bearings have a contact angle and are suitable for radial and unidirectional axial or combined loads.
• Due to its structure, an axial component force is generated when a radial load is applied. Therefore, use two units facing each other or a combination of two or more units.
• Due to the difference in contact angle, Angular Contact Ball Bearings have different load conditions at the contact area between the ball and the inner and outer rings when the same load is applied, resulting in different elastic deformation and stress at the contact area.
• When an axial load is applied, the larger the contact angle, the smaller the rolling element load and the less the load on the contact area.
• When a radial load is applied, the smaller the contact angle, the smaller the rolling element load and the less the load on the contact area.
