| Lubrication Components and Systems
SKF has more than 100 years of experience with rotating equipment. We understand the challenges and solutions. Now more than ever, being able to integrate technologies and combine knowledge areas is key. To lead the way, SKF has pursued advanced research and development in tribology.
Today, we continue to invest vigorously in the support of groundbreaking innovation in several technological areas. This is one of the reasons why SKF has a knowledge of lubrication that is unmatched. With the acquisition of the VOGEL Group and Safematic lubrication systems, both now part of SKF, we have strengthened our engineering capabilities and knowledge in customizing lubrication systems.
We can now offer a complete range of lubrication solutions, from specialized lubricants and manual lubricators to the most sophisticated automatic and centralized lubrication systems on the market.
Integrating knowledge and innovation
SKF is able to combine knowledge and experience in the areas of bearings, seals, services, mechatronics and lubrication systems to support broader lubrication management needs. We are also at the forefront in tribology, the combination of friction, wear and lubrication sciences.

Centralized Lubrication Systems
SKF Centralized lubrication systems perform the task of supplying individual lube points or group of points with varying amounts of exactly metered lubricant from one central location. Care taken during the installation, start-up and maintenance of the central lubrication system, will help to enhance the operating readiness and life of your machines.
SKF offers a reliable and comprehensive centralized lubrication system portfolio. The differences in the system types are based on the necessary components needed. Take a closer look at the SKF lubrication system components broad range to get more knowledge in the planning, installation and maintenance of your centralized lubrication system.
In a lubrication system a lubricant is feeded (by a feed pump) and distributed into the needed amount (by distributors, dosers or feeders). The lubrication system is monitored and controlled (by monitoring units, pressure and lubricant switches, control units, etc.). Fittings and assecories completing the components of a lubricaiton system.

Feed pumps
Lubrication pumps feed lubricant from the lubricant reservoir into the tubing system of the centralised lubrication system.
The manometric pressure has to be high enough to compensate for pressure drops in the tubing, components (filters, valves, distributors) and friction points.

Differentiating criteria for feed pumps
- Principle of operation
oscillating and rotary positive-displacement pumps
- Type of drivemanual, mechanical, pneumatic, hydraulic, electrical (electric motor, electromagnet)
- Type of centralised lubrication systemTotal loss lubrication (piston pumps for single-line, dual-line and multiline systems)
Circulating oil lubrication (gear pumps, gerotor pumps, rotary piston pumps, vane pumps for single-circuit and multicircuit systems)
- Pump designPump unit without reservoir or for flange mounting on to a reservoir, unit complete with reservoir, compact unit

Lubricant distributors
Distributor delivers preset lubricant dosage to lubrication point or measure lubricant out to lubrication points over a specified period of time.
Main distributor types are: single-line distributors, progressive feeders, dual-line distributors, metering valve distributors and injection oilers/micropumps. Also customized models available.

Monitoring devices
The functioning of centralized lubrication equipment is monitored by means of monitoring devices. Various devices that generate a visual or electrical signal can be used for this purpose. These signals are analyzed by the electronic control and monitoring devices and provide appropriate information to the machine's control unit or operator.
The following values are used to monitor centralized lubrication systems:
|
- Level of the lubricant in lubricant reservoirs
- Pressure in the tubing of the centralized lubrication system
- Flow (qualitative) in the tubing
- Volume (quantitative) in the tubing
- Oil/air mixtures in the tubing
- Dirt in the filters
- Movement of display elements
- Temperature in the lubricant reservoir and bearings
- Moisture in lubricants
|
|
The monitoring devices also include:
|
- Lubricant level switch
- Pressure switch and transmitters
- Flow monitor
- Volumetric meter
- Oil-streak sensors
- Dirt indicator, differential pressure switch
- Motion display, piston detectors
- Temperature measuring devices
- Moisture sensors
