Manufacturer
SKF (Svenska Kullagerfabriken) is a Swedish group with a wide range of products and services in the areas of rolling bearings, seals, lubrication and systems, mechatronics (preload tools) and related services such as maintenance and training.
SKF was founded in 1907 and grew into a quick global company. The first factory was built in Gothenburg (Sweden), where the international headquarters of the SKF Group is still located today. The Group is present in more than 130 countries and employs around 44,400 employees, has 15 technology centers, 103 production sites and works with round 17,000 authorized distributors.
SKF single-line lubrication systems
Single-line lubrication systems are centralized lubrication systems that have been specially developed for machines and systems with several lubrication points. They work with a main line that transports the lubricant from a pump to progressive or metering distributors. This ensures uniform and reliable lubrication of all the connected components. It is also possible to connect multiple machines. All the feed distributors work almost in parallel. Speak to one of our specialist advisors for a consultation.
Application
Single-line lubrication systems by SKF and Lincoln
This animation demonstrates system components, operating principles and typical applications. SKF single-line lubrication systems are simple to design and easy to expand or reduce. These systems work reliably in a wide range of applications and effectively under harsh conditions. This animation shows the components of such systems and how the lubricant is delivered from a pump unit to the lubrication points via metering devices. Monitoring and control options are also covered.
SKF dual-line lubrication systems
Efficient lubrication for large systems - SKF dual-line lubrication systems work with two main lines that are alternately supplied with up to 400 bar by a high-pressure pump. The lubricant reaches the distributors via branch lines, which deliver large quantities of grease to the lubrication points in a targeted manner. Final pressure switches monitor the process and control the changeover process.
These systems are flexible, easy to expand, and do not require reconfiguration for adjustments. They function in two half-cycles, in which one main line is pressurized while the other is relieved. The number of lubrication points can be further increased by combining them with progressive distributors.
Application
Dual-line lubrication systems - For harsh conditions
Dual-line lubrication systems work with two alternately pressurized main lines that transport the lubricant to the lubrication points via distributors. They are flexibly expandable and can be combined with progressive distributors. The system works in two half-cycles: In the first, lubricant is pumped into one main line while the other is relieved. Once the set pressure is reached, a final pressure monitor sends a signal to the control unit, whereupon the pump stops and the changeover takes place. This ensures that all lubrication points are supplied precisely.
SKF multi-line lubrication systems
SKF multi-line lubrication systems supply each lubrication point with lubricant directly from a pump via separate lines. This enables independent control of the lubricant quantity for each lubrication point. The multi-line pumps are available in mechanically, electrically or hydraulically actuated versions. Multi-line pump units deliver the lubricant directly to the lubrication point; no lubricant distributors are required. Each lubrication point has its own pump element.
SKF Progressive Lubrication Systems
Reliable lubrication for small to medium-sized machines with SKF progressive lubrication systems ensures continuous lubrication as long as the pump is running. The lubricant is delivered to the lubrication points in precise quantities via main and sub-distributors. A block interrupts the lubrication of the entire system and serves as a monitoring feature that warns maintenance personnel in good time.
Application
Progressive lubrication systems
SKF progressive lubrication systems are flexible, reliable and reduce friction and wear in various industries. They precisely supply up to 150 lubrication points with lubricant over distances of around 15 m, and even over 100 m for oil lubrication systems. They also offer monitoring and control options for optimum lubrication and cost reduction.
SKF circulating oil lubrication systems
Lubrication and cooling in one - SKF circulating oil lubrication systems lubricate and cool highly stressed bearings and gears, while the circulating oil removes dirt particles and reduces wear. With flow rates from 0.1 to 3000 l/min, they offer flexible and expandable solutions for a wide range of applications. Easy to operate and modular in design, they are easily expandable and can be monitored optically or electronically. SKF oil circulation systems increase operational reliability and support predictive maintenance concepts.
Components for lubrication systems
Lubrication pumps and pump aggregates
Lubrication pumps convey lubricant into automatic lubrication systems and ensure the required pressure. The selection depends on the system type, drive, design, lubricant quantity as well as pressure and temperature requirements.
Areas of application
- Single-line, dual-line and progressive lubrication systems
- Multi-line and small oil circulation systems
- Small oil circulation systems
Lubricant distributor
Lubricant distributors guarantee the targeted supply of a defined quantity of lubricant to individual or several lubricating points. To select the right distributor, the following criteria are important: The style of lubrication system, type of lubricant and the quantity used should be known, the pressure and temperature range as well as the mode of operation of the distributor.
Areas of application
Suitable for single-line, dual-line, progressive, multi-line and recirculating oil systems
Monitoring of lubrication systems
Control units control lubrication processes, regulate pause times and monitor system values. At malfunctions, they send warning signals to prevent damage. In oil circulation systems, this task is often performed by the machine control system. Lubrication times, pressure, lubricant quantity and stand as well as the number of lubrication cycles are recorded for function control.
Areas of application
- Single-line, dual-line and progressive lubrication systems
- Multi-line, oil circulation and oil-air lubrication systems
- Minimum quantity lubrication
Control units and software for lubrication systems
Control units regulate the operation of lubrication systems by automatically starting lubrication cycles, setting pause intervals and monitoring relevant system data. At deviating values or malfunctions, they make of warning signals to prevent failures and damage. In oil circulation systems, this task is often performed by the machine control system. Parameters like lubrication times, pressure ratios, lubricant quantity and fill level are recorded. The number of lubrication cycles is also monitored to ensure that the system functions reliably.
Software enables the remote monitoring and control of various lubrication systems, including single-line, dual-line, progressive and minimum quantity systems.
