Specification of Double Row Cylindrical roller bearings:
Double row Cylindrical roller bearings belong to separable bearings, whose inner and outer rings are linearly contacted with rollers. They have small friction coefficient, bigger capacity of bearing radial load and are applicable to both bearing heavy load and impact load and high-speed rotation. Cylindrical roller bearings have the advantages of compact structure, strong stiffness, big bearing capacity, small deformation after loaded etc.
CNBM has already successfully developed split cylindrical roller bearings which can be freely installed at any time and any place, to meet the demand of driving and conveying rollway bearings at cooling area of continuous casting. CNBM also can provide special cylindrical roller bearings according to requirement of customers.
Product Application:
- Iron and steel metallurgical industry
- Medium and large motor
- Generator
- Combustion engines
- Machine tool spindle
- Speed reducer
- Loading and unloading machinery and all kinds of industrial machinery
Double row cylindrical roller bearings
- NN double row cylindrical roller bearings
This kind of bearings with inner rid, no outer rid. This assembly part can be separated from another ring, and they have larger radial load capacity than other single row cylindrical roller bearings with the same size, but the axial or housing is free axial displacement, so this kind of bearings can only bear the axial load.
- NNU, NNU…K double row cylindrical bearings
NNU,NNU...K type bearings with outer rid, no inner rid. There are tow kinds of holes, one is cylindrical hole, and another is tapered hole. Axial or housing is free axial displacement, so this kind of bearings can not bear the axial load. But these kind of bearings have larger radial load capacity than other single row roller bearings with the same size.
- NUP single row cylindrical roller bearings
NUP type bearings with double outer rid, single inner rid and loose rid, this design is possible to limit the axial displacement of the shaft or the housing in double direction within the scope of the axial clearance. in addition they mainly used to bear radial load, also can withstand diameter, the axial union load. Therefore this NUP suitable for fixed end bearings.
- NNCF double row cylindrical bearings
NNCF type bearings with three inner rids and one outer rid. They can take a direction axial positioning. There is a fixed ring in the other side of the outer rid, it can make bearing keep as one.

- Q:How should I find the concentricity of cylindrical roller bearings after installation?
- Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust.
- Q:How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q:Full use roller bearings
- The FAG space division has also been involved in the development of bearings and other NTN precision components for Airbus wide body passenger aircraft A380 engines. The fuel efficient Boeing 787 aircraft reduces consumption by 20% compared to similar NACHI aircraft fuels, thanks to its improved aerodynamics, better operating systems and lighter materials. From the general electric KOYO GEnx engine and the Trent 1000 engine Rolls-Royce also play a role in ensuring that the airplane plays a key role more fuel-efficient. This high performance, lighter weight engine bearing support also plays a key role in the engine. FAG Aerospace entered the concept of bearing development, the engine as early as 2005. TIMKEN bearings, China's general agent, the first prototype manufactured bearings are available in 2006 to provide general electric and Rolls-Royce, FAG rolling bearing device design factors. The first engine test operation, which took place in the fall of 2006, achieved very positive results. The civil aviation authority's approval process for the two engines will be completed by the end of 2007.. In the summer of 2008, the first batch of FAG bearings was delivered to the airline. The main production base for the FAG China production base in Shanghai and INA roller bearing Chinese sales center, as well as Germany, Canada, Sweden SKF bearing China general agent of American Timken FAG office production base. The key role of space rolling bearing FAG in Rawls Royce and general electric engine plays, FAG bearing supply of Boeing 787 aircraft, Japan NMB bearings, the two engines for the new long haul aircraft rely on Aerospace Corporation of FAG rolling bearing

- Q:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?Semi convex, convex roller is in plane roller axis, the outer surface of a continuous or discontinuous convex curved basic cylindrical or conical roller, to prevent the end of the roller and raceway contact stress concentration. The roller is generally defined as a convex roller and a modified roller.
- Q:What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- Q:Why are there no double row cylindrical roller bearings in the mechanical design manual?
- but they move axially with the roller and the outer ring?If so, the cylindrical roller bearings without bearings on both sides of the bearing should be normal
- Q:Why are cylindrical roller bearings suitable for traveling support?
- Should be the inner ring and the outer ring without the edge of the can do moving support. Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.
