13 best cylindrical roller bearings
Cylindrical roller bearings are a type of rolling element bearing used in various industrial applications to support radial loads while allowing for limited axial movement.These bearings consist of cylindrical rollers held between two bearing rings, typically an inner ring and an outer ring, and are widely employed in the field of power transmission and machinery. Here's what you should know about cylindrical roller bearings:
Purpose: Cylindrical roller bearings are designed to provide high radial load-carrying capacity, making them suitable for applications where heavy radial loads need to be supported, such as in electric motors, gearboxes, conveyor systems, and automotive transmissions.
Design: Cylindrical roller bearings consist of the following key components:
- Inner Ring: The inner ring is mounted onto the shaft and rotates with it.
- Outer Ring: The outer ring is usually stationary and provides support for the bearing.
- Rollers: Cylindrical rollers are positioned between the inner and outer rings. These rollers are designed to distribute the load evenly, reducing friction and wear.
- Cage: Some cylindrical roller bearings have a cage or separator to maintain proper spacing and alignment of the rollers.
Types:
- Single Row: These bearings have a single row of cylindrical rollers and are suitable for moderate radial loads.
- Double Row: Double row cylindrical roller bearings have two rows of rollers and can handle higher radial loads and limited axial loads.
- Full Complement: These bearings have no cage and contain the maximum number of rollers, providing high load-carrying capacity.
Applications:
- Cylindrical roller bearings are commonly used in various industrial machinery, including pumps, compressors, printing machines, and paper mills.
- They are also utilized in automotive applications, such as wheel hubs and transmissions.
- In the aerospace industry, cylindrical roller bearings are used in aircraft engines and landing gear systems.
Axial Movement: While primarily designed for radial loads, cylindrical roller bearings can accommodate limited axial movement or thrust loads when necessary.
Lubrication: Proper lubrication is essential for the long-term performance of cylindrical roller bearings. Lubricants reduce friction, dissipate heat, and prevent premature wear and failure.
Maintenance: Regular maintenance, including lubrication and inspection for wear and damage, is important to ensure the continued functionality and longevity of these bearings.
Installation: Correct installation practices, such as proper alignment and torque specifications, are critical to prevent premature bearing failure.
Seals and Shields: Cylindrical roller bearings may come equipped with seals or shields to protect the bearing's internal components from contamination and to retain lubrication.
Sizes and Configurations: Cylindrical roller bearings are available in a wide range of sizes and configurations to suit various application requirements.
In summary, cylindrical roller bearings are crucial components in many industrial and mechanical systems, providing efficient support for radial loads and limited axial movement. Their versatility, load-carrying capacity, and wide range of applications make them a fundamental element in the field of power transmission and machinery. Proper maintenance and installation practices are essential for maximizing the performance and lifespan of cylindrical roller bearings.

User questions & answers
| Question: | Are the r8 bearings shielded on both sides |
| Answer: | Yes, you should be able to do that. Just don’t overtighten it the first time. If you do, you will deform the washer and it will leak when you put it on the second sink. |
| Question: | What is the bore size of the r8-2rs ? I need a precision bearing with a 1/2 inch bolt |
| Answer: | I needed about 12 inches for lines. The 16 inch lines worked fine with any kinks. Also available in 12 inch. |
| Question: | What are the thickness of the r8-2rs bearings |
| Answer: | Not enough information. 1) Is A) water coming out but it is not hot, or B) is no water coming out? 2) Are you A) installing new plumbing/fixture, or B) replacing existing plumbing fixture? Re: 1) - If 'A' check water heater, if 'B' check supply, plumbing and fixture. Re: 2) - If 'A' start at source, check that both supply lines flow, then attach supply hoses & check, then attach to fixture and check. Re: 2) - if 'B', assume you turned off water at BOTH supply lines, make sure you turned water back on at BOTH supply lines |

INA
Product description
This INA cylindrical roller thrust bearing with a polyamide nylon cage is suitable for applications that support axial loads in one direction. The polyamide nylon cage is lightweight and produces less noise than brass cages. It has an open-end design, allowing lubrication to be applied in place. This bearing uses metric unit measurements for industry consistency and interchangeability and meets quality assurance specification s Deutsches Institut für Normung (DIN) 722/ International Organization for Standardization (ISO) 104 for roller thrust bearing boundary dimensions. Cylindrical roller thrust bearings are used in applications where high axial loads are present, such as automotive transmissions, material handling equipment, and lifting mechanisms, among others.
Roller or rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction. They are usually composed of two rings, rolling bodies (such as bearings or cylinders), and a cage to house the parts. Cylindrical roller thrust bearings are suitable for applications that are required to support heavy axial loads and are used when thrust ball bearings or thrust needle bearings have insufficient load-carrying capacity. They are not suitable for transmitting radial loads. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, automotive transmission, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
INA manufactures rolling bearings, plain bearings and linear systems for the automotive industry. The company, founded in 1946, is headquartered in Herzogenaurach, Germany, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
