The design of SLR5205 KDDU double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings, but only takes up a smaller axial space. The double row angular contact ball bearing can bear radial load and axial load acting in two directions, it can limit the axial displacement of the shaft or housing in both directions, and the contact angle is 30 degrees. A bearing configuration with higher rigidity can be provided, and it can withstand the overturning moment.

EASIER/TKW Can supply complete Double Row Angular Contact Ball Bearings

Double row angular contact ball bearings can withstand larger radial loads, mainly combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. Mainly used in components that limit the bidirectional axial displacement of the shaft and the housing.

(1) The standard design of type A bearing whose outer diameter is less than or equal to 90mm. There is no notch for ball loading, so it can bear equal bidirectional axial load. The light-weight glass fiber reinforced nylon 66 cage is adopted, and the temperature rise of the bearing is small.

(2) The standard design of type B bearings with an outer diameter greater than 90mm. There is a ball-loading gap on one side, and it is equipped with a steel stamping cage or a brass solid cage.

(3) Type C is a reinforced structure, with a ball notch on one side, which can hold more steel balls, so the load-bearing capacity is higher.

(4) The double row angular contact ball bearings with dust cover on both sides and seal ring on both sides A and C design can be equipped with dust cover (non-contact) or sealing ring (contact type) on both sides. ). The inside of the sealed bearing is filled with anti-rust lithium grease, and the operating temperature is generally -30～+110℃. No relubrication is required during use, and it should not be heated or cleaned before installation.

Compared with single-row angular contact ball bearings, the production of double-row angular contact ball bearings has the same processing technology, but it is more difficult to process. It is necessary to ensure that the balance of the bearing channel is poor during the processing. A slight deviation will affect the bearing The service life, speed, noise, etc. have a relatively large impact, so double row angular contact ball bearings are the same as double row deep groove ball bearings. Only by grasping the balance of the bearing channel can the quality of the bearing be ensured. In order to ensure the high quality of the products, our company specially updated the turning processing, grinding processing equipment and inspection and testing equipment, and improved the processing of operation...

The tiltability between the inner and outer rings of double row angular contact ball bearings is limited. The allowable tilt angle depends on the bearing's internal clearance, bearing size, internal design, and the force and moment acting on the bearing, and the maximum allowable tilt angle should be guaranteed No excessive additional stress is generated in the bearing.
