FAQ:

Q: What is a roller bearing?
A:  A roller bearing is a type of rolling-element bearing that uses a cylinder (roller) instead of a ball. In general, the cylindrical bearings allow for greater radial loads. They are made to handle heavier loads than ball bearings.

Q:What is the difference between roller and bearing?
A: A roller bearing is a cylindrical unit that is used to provide low-friction movement for a bushing or bearing block. A ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail.

Q: Which bearing is used in heavy machinery?
A: Standard bearings – commonly used bearing types in construction and heavy machinery: Spherical roller bearings.

About Bearing:

Roller bearings are a widely used mechanical component primarily for supporting and turning rotating shafts in machinery and equipment. Compared with other bearings, roller bearings have the following characteristics: Large bearing capacity: The structural design of the roller bearing enables it to bear large radial and axial loads. Smooth rotation: The rolling elements inside the roller bearing can form a rolling contact between the shaft and the bearing, thereby reducing friction and wear and making the rotation more stable. Wide adaptability: There are many types of roller bearings, which can adapt to different working conditions and requirements, such as high speed, high temperature, low noise, etc.
