cylindrical roller bearing manufacturers

Cylindrical roller bearings, also known as a rolling bearing, carry a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The cylindrical roller bearings have a high radial load capacity and are suitable for high speeds. They vary according to the number of rows of rollers (usually one, two, or four) and if there’s a cage or not. No cage allows for the bearing to have more rows, which helps support even heavier radial loads.

cylindrical bearing types

Single Row Cylindrical Roller Bearings

Single row cylindrical roller bearings are a kind of cylindrical roller bearings manufactured with snap ring grooves on the outer rings.

Double Row Cylindrical Roller Bearings

Double row cylindrical roller bearings have two structures: cylindrical inner bore and conical inner bore.

Four Row Cylindrical Roller Bearings

Four-row cylindrical roller bearings are mainly used in rolling mill machinery such as cold and hot rolling mills and opener mills.The bearing is of a separate structure, and the bearing ring and rolling element components can be easily separated. Therefore, the bearing is cleaned and inspected. Or installation and disassembly are very convenient.

There are many types and sizes of cylindrical roller bearings including tapered, needle and spherical. Most of these are single row bearings with a cage. The cage prevents the rolling elements from colliding into one another, which helps reduce friction, wear and prevents bind.
Single row cylindrical roller bearings
This type of bearing is often used to support radial loads. Only single-row bearings with ribs on both inner and outer rings can support low constant axial loads or high axial interval loads. Compared to deep groove ball bearings with the exact dimensions, the radial load capacity of this type of bearing is greater.
Double row cylindrical roller bearings
There are two inner bores in double row cylindrical roller bearings: cylindrical bore and tapered bore. They have the characteristics of a small section, high bearing capacity, and good rigidity. They are mainly used in machine tools, rolling mill necks, plastic rolls, grinding machines, and large gearboxes.
Four row cylindrical roller bearings
This type of bearing is known for its simple structure, high accuracy, high dynamic load rating, etc. Because the inner ring has no rib, the inner and outer rings with components can be mounted separately. Therefore, they are easy to mount and dismount and are the first choice for various cold and hot rolling mills.
Single Row Full Complement Cylindrical Roller Bearings
A single row full complement cylindrical roller bearing is a cylindrical roller bearing. Single row full complements cylindrical roller bearings have solid outer and inner rings and rib-guided cylindrical rollers. Since these bearings have the most significant possible number of rolling elements, they have extremely high radial load carrying capacity and rigidity. They are suitable for particularly compact designs.
Double Row Full Complement Cylindrical Roller Bearings
A double row complete complements cylindrical roller bearing is a cylindrical roller bearing. Double row full complement cylindrical roller bearings are designed to withstand heavy loads. Under the same width, this kind of bearing has a very high load carrying capacity compared with the traditional bearing with a cage. Double row full complement cylindrical roller bearings can withstand large radial loads.
Thrust Cylindrical Roller Bearing
All thrust cylindrical roller bearings have an optimized roller and raceway contact lines design to avoid edge effects. Moreover, the bearings are of separate construction, where the shaft, seat ring, and cage roller set can be mounted separately.The axial structure of thrust cylindrical roller bearing is very compact and can withstand a substantial axial load, withstand shock load, and have good rigidity.We produce one-way, and two-way thrust tapered roller bearings.

Some FAQ About cylindrical bearing rollers

What is advantages of cylindrical roller bearing?
  • Separable design for simple mounting & dismounting.
  • Interchangeable design Inner Ring can exchanged.
  • Suitable for high speed applications.
  • Heavy radial loads.
  • Accommodates axial displacement.
When would you use a cylindrical roller bearing?
Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
Ball Bearing Vs Cylindrical Bearing

As a general rule, ball bearings are used for higher speeds and lighter loads than roller bearings. Roller bearings perform better under impact and impact loads.

Ball bearings are usually sold as components and can only be replaced as units. Roller bearings can usually be removed, and the roller holder and roller, or outer or inner ring, can be replaced separately. The front wheels of a rear-wheel drive car are arranged in this way. The advantage of this design is that the seat can be retracted to fit into the shaft and housing to form a permanent component without damaging the roller itself.

Why does a cylindrical roller bearing require a heavy duty separator?
The role of the separator is to maintain an equal distance between the rolling elements. The races are the outer ring or the inner ring of a bearing. The raceway is the path of the rolling element on either ring of the bearing.
Why choose a cylindrical roller bearing over a radial ball bearing?
Cylindrical roller bearings are similar to radial ball bearings in that they are designed to carry a radial load while minimizing friction. Cylindrical roller and radial ball bearings can also handle a small amount of axial loads depending on the application and internal design of the bearings.

In general, roller bearings offer higher load capacities than ball bearings of the same size. The other significant difference between the two bearings is their contact area. For ball bearings, the contact area is a single point where the roller bearings hit a much larger area.

Basic & knowledge



Cylindrical roller bearings are used in a variety of applications. Examples include mining, petroleum production, power generation, transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools, traction motors and pumps.



Cylindrical roller bearings are as flexible as approaches come. Their components are interchangeable with other manufacturers’ directions with the same dimensional size and number. The mounting arrangements can be configured in various ways and match the load capacity for a given width, inner diameter, and outer diameter.
Cylindrical roller bearings can have rings that move freely in the axial direction (for bearings without ring ribs) for applications that experience a thermal expansion of the shaft.



Most cylindrical roller bearings are made of alloy or low-carbon steel. Some applications require case-hardened or through-hardened, high-carbon, bearing-quality steel. High-carbon steel grades do not require carburizing and can be case-hardened by induction heating or through-hardened by conventional heating methods. When low-carbon, carburized steel grades are used, carbon is introduced after the cylindrical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a complex, fatigue-resistant case and a rigid, ductile core.

"NU, N, and NN are often free-end (“free” or “float”) bearings and are installed on the shaft away from the drive end. NJ and NF offer axial resistance in one direction, while the NUP offers axial resistance in both directions, can be used as fixed-end bearings, and is installed near the drive."

Bearing Types

"Cylindrical roller bearings utilize a cage or are manufactured as a full complement bearing to accommodate higher loads at the expense of speed. Steel, brass, and polyamide cages are common.Most applications, and even high-heat applications, benefit most from a steel cage. "


"The inner and/or outer rings of cylindrical roller bearings guide the rollers with ribs. Ring assemblies are separable for ease of installation and press-fit individually onto the shaft and into housing.The “ribless ring” of a cylindrical roller bearings move axially and are used as a free-end, or float bearing."


"The rollers inside cylindrical roller bearings are critical components because of their role in load distribution. Through a line contact between the rollers and the raceway, radial load capacity and impact load capacity for cylindrical roller bearings is as robust as it comes."
