Pioneer of rolling bearing technology-FAG bearing

wallpapers News 2021-03-12
Founding Introduction
FAG bearings are inspired by the genius, the great inventor Friedrich Fischer (Friedrich Fischer). In 1883, Friedrich Fischer designed a special steel ball grinder for the first time from the small town of Schweinfurt in Germany to make a complete spherical steel ball possible. This idea is considered to be the historic beginning of the rolling bearing industry, which is why FAG has long been recognized as a pioneer in rolling bearing technology. In the world's major industrial countries, there are companies, branches and sales agents. FAG Bearing produces a variety of ball bearings and roller bearings with an outer diameter ranging from 3 mm to 4.25 m.
Structure type
1. Structure type
The basic structure of the four-row cylindrical roller bearing has lubricating oil grooves and oil holes in the radial direction of the outer ring and the FCDP type spacer ring.
The FAG bearing is a technical FAG spindle bearing: the spindle bearing is a single row angular contact ball bearing composed of a solid inner ring, an outer ring, a ball, and a cage assembly with a solid window cage. They cannot be removed. These bearings can be open or sealed. The tolerances of spindle bearings are limited. They are particularly suitable for bearing arrangements that require very high steering accuracy and speed capabilities. They are particularly suitable for the bearing arrangement of the shafts of machine tools.
Four-row cylindrical roller bearings have four basic structural types:
FC type: (one inner ring) four-row cylindrical roller bearings.
FCE type: an improved type of FC type, the outer ring has no middle ribs (the roller length is lengthened), and the cage is a window structure, which can make the load-carrying capacity about 20% higher than that of the FC type, so it is also called the reinforced type.
FCD type: Four-row cylindrical roller bearing with the double inner ring.
FCDP type: Four-row cylindrical roller bearing with the double inner ring and flat retaining ring on the outer ring.
2. Main types
Deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, outer spherical bearings, needle roller bearings, linear bearings, self-aligning ball bearings, spherical roller bearings, thrust ball bearings, thrust rollers Bearings, joint bearings, etc.
Scope of application
Since 2001, FAG bearings have played an active and important role in the group's aerospace, automotive and industrial fields, covering all applications in the production machinery, power transmission and railway, heavy industry and consumer goods industries.
