Caution

thận trọng

  • The value in the "Width (mm)" column of the product specifications is the value for a single column even in the case of a combination of multiple columns. (Catalog B dimension)Please note that the width of the actual multi-row combination is twice the stated dimension (2B).

Product Description

Angular ball bearings that can receive a certain amount of axial (axial direction) load.
[Features]
・ The straight line connecting the contact points between the ball and the inner and outer rings has an angle with respect to the radial direction.
・ Radial load and unidirectional axial load can be applied.
・ When a radial load acts, an axial component force is generated, so 2 are generally used facing each other.
[Applications]
・ Ideal for machine tools, feed screw mechanisms, ball screw support units, etc.

Angular Ball Bearing Product Feature Details
This permissible rotational speed is the permissible rotational speed that can be achieved based on the following assumptions.
・ Using
under conditions where an appropriate amount of grease is sealed, and the heat generated by sufficient familiar operation, cooling of the outer cylinder, etc., is removed.
・ Use with constant pressure preload.

Type, structure and features of angular ball bearings

Angular ball bearings are non-separable bearings, and the straight line connecting the contact points between the ball and the inner and outer rings has a certain angle (contact angle) with respect to the radial direction. (Refer to Figure 1)The contact angle and contact angle symbol are shown in Table 1.
A radial load and a unidirectional axial load can be applied. Also, when a radial load acts, an axial component force is generated, so two are generally used facing each other. Table 2 shows the angular ball bearing,
Table 3 shows the combination angular ball bearings. For bearings with a contact angle of 15° and bearing accuracy of JIS 5 class or higher, refer to Precision Rolling Bearing (CAT. No. 2260/J).

Table 2 Classification and characteristics of angular ball bearings

ClassificationFeatures
Standard type・ The bearing series includes 79, 70, 72, 72B, 73 and 73B.
・ The contact angles are 30° and 40° (with B).
・ The standard retainer type depends on the bearing model number. (Please refer to Table 4)

Table 3 Combination type and features of combination angular ball bearings

Combination TypeFeatures
Back combination
(DB)
・ It can receive radial load and axial load in both directions.
・ Since the distance l between the working points of the bearing is large, the load capacity of the moment load is large.
・ The allowable tilt angle is small.
Front combination
(DF)
・ It can receive radial load and axial load in both directions.
・ The distance l between the working points of the bearing is small, and the load capacity of the moment load is small.
・ The permissible tilt angle is larger than the back combination.
Parallel combination
(DT)
・ It can receive radial load and unidirectional axial load.
・ Since 2 pieces receive an axial load, a large axial load can be received

Remarks 1. Since the bearings are manufactured as a set to adjust the internal clearance or preload amount of the bearings, bearings with the same product number must be used in combination.

Frequently asked question (FAQ)FAQ

Question:Question: What is an angular contact ball bearing?
Answer:Answer: An angular contact ball bearing with a contact angle is suitable for applications requiring high precision and high-speed rotation and can accommodate combined loads. The contact angles are 15°, 30°, and 40°; the smaller the contact angle, the more suitable it is for high-speed rotation. Conversely, the larger the angle, the greater the axial load capacity.
Question:Question: In what ways are angular contact ball bearings inferior to other bearings?
Answer:Answer: While deep groove ball bearings can bear axial loads from both directions, angular contact ball bearings can only bear axial loads from one direction.
Question:Question: What applications are they suitable for?
Answer:Answer: They are suitable for high-precision machinery and machines that require high-speed rotation. They are used in applications such as precision machinery, spindles, and power tools.
Question:Question: What are the maintenance considerations?
Answer:Answer: Proper lubrication and appropriate installation are crucial. Overloading and improper handling can lead to failures.
Question:Question: What is the operating temperature range?
Answer:Answer: Angular bearings are generally used within a temperature range of approximately -30°C to 120°C under normal operating conditions. We also have some types of products which can be used in high temperature range. Therefore, please check our e-Catalogue & manufacture's Catalogue.
Question:Question: What is the difference between single row and Combination types?
Answer:Answer: The single row type can only accommodate axial loads in one direction, while Combination types can accommodate axial loads in both directions and has higher axial load capacity and stability compared to the single row type.
