Spindle bearings are a special type of single-row angular contact ball bearings. They are often used in the manufacturing of machine tools, as well as in the range of applications with high to extremely high demands in terms of accuracy or permissible speed required by the mounting/ bearing installation.
In comparison with standard angular contact ball bearings, spindle bearings are distinguished by the contact angle, the tolerance classes, and the cage design. Spindle bearings can be delivered with a contact angle of 15° or 25°.
Spindle bearing BS series
The BS719 and BS70 series use a larger number of smaller diameter balls than the B719 and B70 series with identical external dimensions. As a result, higher speeds can be achieved compared to the standard series. The BS series represents a high-performance bearing concept for demanding spindle units that is economical for the customer.
In their main dimensions, high-speed spindle bearings are identical to spindle bearings in the B series. They are particularly characterized by their suitability for higher speeds, as well as by lower friction and heat build-up, and are manufactured in the HS719 and HS70 series.
Miniature bearings are small bearings with balls as rolling elements, sometimes called instrument bearings or miniature ball bearings, mainly consisting of several parts: outer ring, inner ring, retainer, sealing cover and balls. Raising chastity, miniature bearings present the product data within 10mm inner diameter; there are two imperial and metric miniature ball bearings specifications.
With the continuous development and progress of technology, the industrial applications of drones are gradually expanding. As one of the main segments of civilian drones, the development of mapping drones is also becoming increasingly mature, and the market scale maintains high growth. Drones also show a trend of diversification in applications and are favoured by users in various industries.
Some bearing manufacturers use different names for the same type of products. In our comparison list, you will find different manufacturers' names representing the same product type. You only need to find the name you are familiar with and the corresponding TFL name in the list.
