Vaca Muerta: bearings, couplings and transmission for pumping, fracturing and compression equipment

Pumping equipment in unconventional fields like Vaca Muerta operates with combined radial and axial loads, vibrations and contamination from formation fluids. For these conditions, spherical roller bearings are a frequent choice because they tolerate misalignment and support high load capacities.

In centrifugal and progressive cavity pumps, spherical roller bearings with E design (such as those identified with standard suffixes) offer higher load capacity and lower friction. SNL split housings complement the assembly, facilitating installation and field maintenance.

For pumping applications with combined loads, tapered roller bearings are also an option, although in Vaca Muerta spherical roller bearings are prioritized for their self-aligning capability. We supply bearings from recognized brands such as SKF, FAG and LINK-BELT, and we quote according to the size or code you need.

Hydraulic fracturing (fracking) equipment uses roller chain transmissions to drive high-pressure pumps and other components. These chains must withstand pulsating loads and operate in dusty and humid environments.

Roller chains with standard pitch, such as ANSI series (for example, 60 or 40), are used in power transmissions. For higher demands, long-pitch or multiple-strand chains, such as 2 or 3 strand, are used, which distribute the load better.

We work with chains from brands such as SKF, TSUBAKI and EMMAR. If you need a specific chain, you can indicate the code or the pitch and number of strands; we quote the appropriate option for your fracturing equipment.

Compressors and pumps in compression plants and pumping stations require couplings that transmit torque efficiently and absorb misalignments. Elastomeric and gear couplings are common in these applications.

In Vaca Muerta, couplings must withstand high temperatures and contamination. Flexible couplings with an elastomeric element help reduce vibrations and extend the service life of associated bearings and seals.

We supply a wide variety of couplings for different powers and speeds. If you provide the distance between shafts, shaft diameters and required torque, we will indicate the alternative that best suits your compressor or pump.

Hydraulic systems of fracturing and pumping equipment depend on hydraulic seals that prevent leaks and withstand high pressures and temperatures. Polyurethane and PTFE seals are common in cylinders and valves.

Lubrication is critical in these environments: greases and lubricants specially designed for high load and water resistance help extend the service life of bearings and chains. In Vaca Muerta, it is recommended to use greases with extreme pressure additives and good adhesion.

We work with hydraulic seals and lubricants from recognized brands. If you indicate the seal dimensions or operating conditions, we will quote the appropriate product for your application.

SNL split housings are a practical solution for mounting bearings in pumping and compression equipment, as they allow bearing replacement without dismounting the shaft. In fields like Vaca Muerta, this reduces downtime.

These housings are made of gray or nodular cast iron and accept spherical roller bearings with adapter sleeves. They are used in pumps, fans and conveyors, among other equipment.

We supply SNL housings in various sizes, such as those identified with standard codes (for example, SNL 211 or SNL 216). If you indicate the shaft diameter or the bearing you will use, we will quote the corresponding housing.

In pumping and compression equipment in Vaca Muerta, spherical roller bearings are widely used for their ability to withstand high radial loads and angular misalignments. Their design with two rows of spherical rollers and a spherical raceway in the outer ring makes them robust.

Within this category, bearings with the E suffix (such as those in the 223 series) have higher load capacity and lower operating temperature. There are also versions with brass cages (MB suffix) for high-demand applications.

We work with spherical roller bearings from brands such as SKF, FAG and LINK-BELT. If you have the bearing code or dimensions (inner diameter, outer diameter and width), we will quote the exact option for your equipment.
