Oil & Gas: Housings, Seals and Bearings for Surface Equipment, AIB and Treatment Plants

In the oil industry, surface equipment such as pumps, compressors, fans and conveyor belts work under demanding conditions: heavy loads, vibration, contamination and variable temperatures. The choice of suitable bearings, housings and seals directly impacts reliability and maintenance costs.

A spherical roller bearing, for example, compensates for shaft misalignments and supports combined radial and axial loads. In applications such as centrifugal pumps or draft fans, this capability is key to avoiding premature failures.

SNL split housings facilitate assembly and disassembly without dismantling the entire assembly, which reduces downtime. Combined with efficient seals, they protect the bearing from the ingress of dust, water and other contaminants present in the field.

Spherical roller bearings are one of the most used options in surface equipment due to their self-aligning capability. They support high radial loads and axial loads in both directions, even with shaft misalignments or structure deflections.

In pumps, gearboxes and winch drums, these bearings contribute to smooth running and longer service life. References such as 22325, 22361 or 20222-MB are common in mechanical pumping equipment and transmission systems.

When selecting a spherical roller bearing, it is important to consider the internal clearance (for example, C3 for applications with thermal expansion) and the cage type. Proper technical advice helps define the correct variant for each service condition.

SNL split housings are designed to accommodate bearings with adapter or withdrawal sleeves. Their two-half construction allows inspection and replacement of the bearing without dismantling the shaft or coupled components.

In the oil industry, where every hour of downtime has a high cost, this feature is an operational advantage. SNL housings are used in fans, pumps, conveyor belts and other rotating equipment.

Models such as SNL 211 or SNL 216 cover a wide range of shaft diameters. When choosing a housing, compatibility with the bearing and the seal type (labyrinth, felt or rubber) must be verified to ensure adequate protection.

Hydraulic seals serve a dual function: retain lubricant and prevent contaminant ingress. In surface equipment exposed to dust, mud, salt water or chemicals, a poor-quality seal accelerates bearing wear.

In hydraulic cylinders of drilling equipment, pumping units and control systems, seals must withstand high pressures and reciprocating motion. Material selection (nitrile, polyurethane, viton) depends on the fluid and working temperature.

References such as 504262 or 504279 correspond to frequently used hydraulic seals. When replacing a seal, it is advisable to verify the exact dimensions and profile type to maintain the system's original sealing.

Roller chains transmit power between shafts in rod pumps, agitators and conveyors. They must withstand shock loads, vibration and abrasive environments. A poorly lubricated chain or one with worn links causes unscheduled downtime.

Standard and high-strength chains are available on the market. References such as PHC 81X-O/L, RS60 or 12-C1 cover different pitch and load requirements. Periodic lubrication and elongation control are basic maintenance practices.

Couplings, on the other hand, compensate for misalignments and dampen shocks in the transmission. In surface equipment, elastic or gear couplings protect bearings and reduce vibration transmission. Correct selection depends on torque, speed and available space.

Adequate lubrication reduces friction, dissipates heat and protects against corrosion. In oilfield environments, greases and oils must withstand high temperatures, extreme loads and contamination with water or dust.

Re-lubrication frequency depends on bearing type, speed, temperature and contamination level. Excess grease can raise the operating temperature; insufficient amount accelerates wear.

For SNL housings, it is recommended to use greases with extreme pressure additives and good water washout resistance. For chains, lubricants must penetrate to the pins and bushings. A well-executed lubrication plan is the most cost-effective investment in maintenance.
