Solutions for All Sectors with RBC Bearings

Since 1919, RBC has been a leading international manufacturer of highly engineered precision bearings and products. These are an integral part of the manufacture and operation of most machines, aircraft and mechanical systems, in order to reduce wear on moving parts, minimize damage and energy loss caused by friction, facilitate the correct transmission of power, and control pressure and flow.

On this occasion we are going to analyze some of its most used bearings.

Ball bearings

Ball bearings are the most common and most used in market applications, their main characteristic being the speed of rotation, which is higher than in other types of bearings.

Among others, RBC offers thin section ball bearings, which are designed to solve design problems that cannot be solved with conventional ball bearings, and are characterized in that their bore diameter is at least 4 times larger than the radial cross section. . This type of bearings can normally operate at temperatures between – 54°C and 121°C, in case the bearings are thermally stabilized they can be exposed up to 177°C, and through the use of special manufacturing materials, they could reach withstand up to 482°C.

Due to the combination of light weight with high stiffness, and the wide variety of models available, this type of bearing is frequently used in applications where space limitations, combined loads and weight restrictions are encountered.

Needle roller bearings

Needle roller bearings are characterized by being made up of cylindrical rollers with a very small diameter relative to their length. They are especially suitable for applications where space is radially limited and have a high load capacity considering the size of their section.

The bearings offered by RBC in their modality without seals or metallic cages are thermostabilized and can be used without loss of capacity in operating temperatures that range between -40ºC and 150ºC, but the temperature limits must always be considered according to the specific model, since that depending on the seal, the cage and the lubricant this tolerance can vary, and RBC offers the option of using other manufacturing materials in case it is desired to expose them to higher temperatures.

Possessing high load carrying capacity and long service life, these types of bearings are commonly found in gear and mud pumps, pump jacks, helicopter rotors and transmissions, crankshafts and marine connecting rods.

Thrust bearings

Thrust bearings are designed to resist force in the same direction as the shaft, which is called an axial load or thrust load.

RBC offers thrust bearings that can be used without loss of capacity at temperatures ranging from -40°C to 149°C. If it is desired to subject the bearings to higher temperatures, there is the option of subjecting them to an alternative heat treatment, but it must be taken into account that this may imply a certain loss of hardness.

This type of bearings are hardened, so they are especially suitable for demanding applications where high loads are present, normally used in trailers, trucks, tractors and construction equipment.

Where can I consult the RBC’s PDF catalogue?

As we have incorporated the RBC’s PDF catalogue to our website, you will be able to consult directly from here all the technical information available on both their bearings and the rest of their products.

However, remember that we also have available in our B2B portal the RBC digital catalogue, from which you can directly request any material from this manufacturer. Finally, you can always use our contact form, email or telephone number to ask us any questions you may have.
