Angular touch ball bearings can accept both radial and axial loads. They can work at higher speeds. The larger the touch angle is, the higher the axial load is. The high precision and high speed bearings usually take a 15 degree touch angle. Under the force effect; the touch angle will increase. The single-row angular touch ball bearing can only accept the axial load in one direction; when receiving the radial load; it will lead to the additional axial force. And can only constrain the shaft or the shell in one direction. Axial displacement.
Pairs of double-ball bearings if paired in pairs; make the outer rings of a pair of bearings opposite; that is, the wide end faces the wide end; the narrow end faces the narrow end. This prevents additional axial forces from being caused; The direction constrains the shaft or the casing within the axial clearance. The angular contact ball bearings can be displaced relative to each other on the horizontal axis due to the raceways of the inner and outer rings; therefore, the radial load and the axial load combined load can be accepted together (single row angle) Touch ball bearings can only accept one-way axial load; therefore, it is usually used in pairs.) The material of the cage is brass, synthetic resin, etc.; it is distinguished by bearing method and operating conditions.
The angular touch ball bearings are mostly made by foreign bearing manufacturers; more domestic applications are applied to imported equipment such as angular touch ball bearings 3204RS, etc.

Indoor Ceiling Light

Indoor ceiling light are lighting fixtures installed on the ceiling of indoor spaces, typically consisting of one or multiple light bulbs and a lampshade or fixture. They can be used to illuminate living rooms, dining rooms, bedrooms, kitchens, hallways, and other indoor areas. Indoor ceiling light come in various designs and materials, and can be selected according to different decorative styles and needs. Some indoor ceiling light are also equipped with remote control or dimmers for better control of lighting brightness and color temperature.
