Moment of inertia is a complex yet intriguing topic, and one testament to this statement is the roller bearings. They are fabricated to carry a load while reducing friction. Instead of using balls, the cylindrical roller bearings transmit loads using cylinder-rolling elements to maintain the separation between moving parts of the bearing.
As the name suggests, cylindrical roller bearings are used as rolling elements and separating mediums. Due to their flat inner surface, the cylindrical roller bearings typically offer a relatively larger contact area on the outer and inner rings. Cylindrical roller bearings find their application where high load capacity and high performance are needed. To help you understand these roller bearings more vividly, here are five things about cylindrical roller bearings that you must know:
FACT #1
For one, the cylindrical roller bearings are designed to handle the radial and impact load at high performance and speed. Due to their specific design, the bearings prove to be one of the most sought options for carrying multiple radial loads. Talking from the design point of view: the cylindrical roller bearings are composed of one outer and one inner ring that is separated by a set of cylinders. These cylinders support both rings and reduce the overall friction. In addition, the cylinders are also supported by a rib cage attached with the outer and inner ring depending on the variation used.
FACT #2
The anticipated efficiency, as well as the effectiveness of the bearings, is unreal. Due to their ubiquitousness, they are an essential part of any machinery with rotating parts. The cylindrical bearings are widely used in electric motors, papermaking industry pumps, railway bearing seals, wind turbines, and gearboxes. The list is long, but the aforementioned industries use cylindrical roller bearings the most due to their durability and high performance even under the most stressful conditions.
FACT #3
The cylindrical bearings can be made with numerous different kinds of materials based on their applications. However, alloy steel is one of the most widely used materials as it offers maximum durability for rollers, rings, and cages. To achieve high acceleration with better performance and speed, some bearings are made with pressed steel too as they can get more carrying capacity without sacrificing durability.
FACT #4
The cylindrical roller bearings come in three variations, and their name is self-explanatory:
- Single row cylindrical roller bearings
- Double row cylindrical roller bearings, and
- Multi-row cylindrical roller bearings.
FACT #5
The Outer Diameter and bore size are substantial specifications that you need to consider while getting cylindrical roller bearings. They affect the amount of pressure the bearings can withstand and their efficiency, so they are significant.
