SKF in oil and gas: bearings for pumping, compression, and surface equipment

In oil and gas, SKF deep groove ball bearings are among the most used in centrifugal and positive displacement pumps. They support moderate radial and axial loads, and their simple design makes them easy to mount and maintain. In crude oil, injection water, or refined product pumping equipment, these bearings ensure smooth and reliable rotation. We supply models such as 6010, 6008, or 6026.

These bearings are identified by the code engraved on the ring, which indicates the series and bore diameter. For example, a 6010 has a 50 mm bore, 80 mm outer diameter, and 16 mm width. In oil applications, they often have seals or shields to protect them from dust and moisture. The 2RS suffix indicates rubber seals on both sides, while 2Z indicates metal shields.

To get a quote for an SKF deep groove ball bearing for oil and gas, it is best to send the complete code, dimensions, or a photo of the part. If the bearing is severely damaged and the code is unreadable, you can measure the bore, outer diameter, and width with a caliper. We distribute SKF bearings for all types of pumps, from small transfer units to large pipeline pumps.

Natural gas and air compressors in oil plants require bearings that can handle high radial loads and high speeds. SKF cylindrical roller bearings are ideal for these conditions, as their design allows the inner or outer ring to be removed depending on the mounting. In reciprocating and centrifugal compressors, these bearings work in critical positions such as the crankshaft or main shaft.

Among the SKF codes in this family that we quote are N3055, RNU 305, and RNU 306. When the shaft acts as a raceway, the mounting requires precise fit and a shaft with adequate hardness, so it is advisable to review the drawing or original part before ordering the replacement.

When ordering an SKF cylindrical roller bearing, it is key to indicate whether a brass, steel, or polyamide cage is needed, and whether the removable ring is the inner or outer. In gas compressors, lubrication and internal clearance are critical: the C3 suffix indicates greater than normal clearance, useful when there is thermal expansion. We quote the exact bearing for your compressor, regardless of the original equipment brand.

In sucker rod pumps, pumping units, and other surface equipment, SKF spherical roller bearings are highly valued for their self-aligning capability. They support shaft misalignment and combined loads, making them ideal for equipment working outdoors or with not perfectly rigid bases. They also appear in pumping heads and gearboxes.

Among the SKF codes in this family are 22325, 22361, and 23666. These bearings have two rows of rollers and a spherical raceway in the outer ring, allowing them to absorb shaft deflections. They are mounted with an adapter sleeve or directly fitted on the shaft.

To get a quote for an SKF spherical roller bearing, send the complete code or the bore, outer diameter, and width dimensions. If the bearing has a tapered sleeve, the K suffix indicates a tapered bore, and the corresponding sleeve must be specified. We distribute SKF spherical roller bearings for surface equipment in the oil industry, from small pumps to large gearboxes.

SKF angular contact bearings are designed to support axial loads in one direction, so they are often mounted in opposite pairs. In oil and gas, they are used in high-pressure centrifugal pumps, turbines, and compressors where there is axial thrust. Their load capacity and rigidity make them indispensable in precision rotating equipment.

Among the SKF angular contact codes we quote are 7417, 7453, and 7829. When replacing them, it is important to respect the mounting direction and the pair arrangement (back-to-back, face-to-face, or tandem) that the equipment had.

When ordering an SKF angular contact bearing, indicate whether it is single or double row, the complete code with suffixes, and the cage type. In high-speed pumps, internal clearance and preload are critical to avoid vibrations. We quote the exact SKF angular contact bearing for your application, with the mounting configuration you need.

Y-bearings, also called inserts, are compact units with a spherical outer ring and a pillow block or flange housing. In oil and gas, they are used in fans, small pumps, conveyor belts, and other auxiliary equipment. Their mounting is simple and they allow some initial misalignment, reducing installation costs.

A typical model is UC 216, an insert bearing with set screws for shaft fixing. Sizes such as UC 315 or UC 212 are also used, depending on the shaft diameter. These bearings are often mounted in cast iron or sheet steel pillow block housings and are grease lubricated. The 2RS suffix indicates rubber seals on both sides, ideal for dusty environments.

To get a quote for an SKF Y-bearing, send the insert code and, if possible, the housing type (pillow block, flange, take-up). A photo of the complete assembly also helps. We distribute SKF Y-bearings and their housings for auxiliary equipment in oil and gas plants.

Gearboxes for sucker rod pumps, compressors, and other oil equipment often use SKF tapered roller bearings. These bearings support combined radial and axial loads and are mounted in opposite pairs to control axial clearance. Their design allows precise preload adjustment, extending the gearbox's service life.

In the oil industry, SKF tapered bearings appear in gearboxes, wheels of mobile equipment, and transmissions. They are identified by the code engraved on the ring, which includes the bore diameter and series. They commonly work with steel cages and require lubrication with high-quality oil or grease.

When ordering an SKF tapered roller bearing, it is essential to indicate whether the complete assembly (cone and cup) or only one part is needed. It is also advisable to specify the desired clearance or preload, as it is critical in gearboxes. We quote the exact SKF tapered bearing for your gearbox, with the corresponding mounting specifications.

In drilling and workover equipment, SKF rod ends and spherical plain bearings are used in mechanical joints that require oscillating motion or angular misalignment. These components are not full-rotation bearings but allow limited movements in various directions. They support heavy loads and severe working conditions, such as vibration and impacts.

SKF spherical plain bearings can be radial, axial, or angular, depending on the load direction. They are press-fitted into housings and grease lubricated. In oil equipment, they are commonly found in loading arms, suspension systems, and adjustment mechanisms. They are identified by the engraved code and the bore, outer diameter, and width dimensions.

To get a quote for an SKF rod end or spherical plain bearing, send the complete code or dimensions and a photo of the part. If the equipment is imported, it may have a code from another brand; in that case, we help you find the SKF equivalent. We distribute SKF rod ends and spherical plain bearings for the entire Argentine oil industry, from Vaca Muerta to refineries.
