What is the difference between ball bearing and roller bearing?

The contact between ball bearing and raceway is point contact, and the contact surface is oval when stressed. Because of the point contact, resisting force value is small, and the ball bearing is suitable for the application conditions of low torque and high rotational speed. They also have the characteristics of low noise. Ball bearings have low loading capacity but can bear radial and axial loads. The contact between roller bearing and raceway is line contact, and the contact surface is square when stressed. Because of the line contact, the torque of roller bearing is higher than that of ball bearing, and its rigidity is higher. Roller bearings have higher loading capacity, and cylindrical roller bearings have retaining edges to bear slight axial loads.

What is the classification of bearings according to the shape of rolling elements?

Rolling bearings are mainly divided into: ball bearings and roller bearings. Among them, ball bearings are divided into: deep groove ball bearings, angular contact bearings and radial thrust ball bearings. Roller bearings are divided into: cylindrical roller bearings, needle bearings, cone roller bearings and self-aligning roller bearings.

What is the classification of bearings according to load direction?

Bearing are divided into: radial bearings and thrust bearings according to the load direction. Among them, radial bearings are divided into: radial thrust ball bearings and radial roller bearings. Thrust bearings are divided into: thrust ball bearings and thrust roller bearings.

What is the basic rated life of rolling bearings?

The basic rated life of rolling bearings refers to the total number of revolutions that 90% of the ball bearings can rotate without peeling when eleven groups of ball bearings of the same kind and specification rotate respectively under the same conditions.

What is the contact angle of this angular contact ball bearing?

The contact angle of this angular contact ball bearing is 25 degrees, and the domestic common usage rate is relatively high.

Product Description

Angular Contact Ball Bearings Single Row
Angular contact ball bearings single row are commonly used in applications that require high-speed and high-precision axial and radial loads. These bearings are available in various sizes to choose from.
[Feature]
● Bearing Size Standards: Metric System
● Inner Diameter Minimum / Maximum (mm.) : 10 and 100
● Outer Diameter Minimum / Maximum (mm.) : 26 and 180
● Width Minimum / Maximum (mm.) : 8 and 34
● Precision (JIS) : Class 5
● Bearing Type : Open (No cover)
● Load Direction : Radial / Thrust Load or Axial Load
[Application]
It is used to support and guide rotating machine's components, such as shafts, wheels, pulleys ,etc

Features

· Because angular contact ball bearings have a contact angle, back-to-back combinations (DB combinations) and face-to-face combinations (DF combinations) can support radial loads and
axial loads in both directions simultaneously.
Parallel combinations (DT combinations) can support radial loads and axial loads in one direction at the same time.
Suitable when the axial load in one direction is large.

Cautions/Prohibitions

If the shaft and housing have poor precision, the bearing may not be able to perform as it should. For example, if the accuracy of the bearing mounting part is poor, this may cause the inner and outer rings to tilt. In this case, in addition to the load applied to the bearing, a peripheral stress centralized load (Edge Load) is also applied, which not only reduces the fatigue life of the bearing, but in severe cases can cause damage such as breakage and seizure of the retainer.

*Please use the following dedicated installation tools to install and remove bearings.

Bearing Heater
ベアリングヒーター

Correct installation of bearing heaters will extend the life of the bearings.
When properly installed and maintained, rolling bearings are reliable mechanical components with a long service life.
If you use an induction heater, the bearing will expand outward in the cylindrical direction after heating, preventing damage during installation.
Heating with induction heaters is the most scientific heating method and does not require preheating and can reach up to 110°C within seconds or minutes depending on the weight of the bearing,
without adversely affecting pre-applied lubrication.

Bearing Puller
ベアリングプーラー

If the bearing is installed in the following conditions, it can be removed using a dedicated puller.
(a) Shaft Shape: Cylindrical Shaft, Bearing Inner Ring I.D. Shape: Cylindrical hole.
(b) Shaft Shape: Cylindrical Shaft, Shape of inner ring I.D. of bearing using adapter sleeve: Positive shaft body hole.
(c) Shaft Shape: Positive shaft body, Shape of inner ring I.D. of bearing: Positive shaft body hole. No matter how it is installed, be sure to unlock the lock nut on the shaft (or the lock nut on the adapter sleeve) and loosen it before removing it.
