Lubricant distributors Product series AB, 341, 340, 351, 350, 391, 390, VR, 321, VN, 370, 361 For oil, fluid grease, and grease For use in SKF MonoFlex single-line centralized lubrication systems SKF MonoFlex single-line distributors are utilized in intermittently operated single-line centralized lubrication systems. They distribute and meter the lubricant fed by an intermittently operated centralized lubrication pump unit in SKF MonoFlex single-line centralized lubrication systems. In each lubrication cycle, a precisely metered quantity of lubricant, ranging from a minimum of 0,01 to a maximum of 1,5 cm³, is fed to the connected lubrication points. The product group of SKF MonoFlex singleline distributors includes a total of 11 different product series consisting of three different functional types (prelubrication, relubrication, and dynamic distributors) for various applications. Comprehensive accessories complete the product range. Depending on the design, SKF MonoFlex single-line distributors are approved for oils with viscosities from 20 to 2 000 mm²/ s, for fluid greases of NLGI Grade 000, 00, and 0, and greases up to NLGI Grade 2. The permissible operating pressures range from 8 to 315 bar, and the relief pressures range from 1 to 70 bar. In addition to the standard designs, several designs are also available in stainless steel. Further, several designs are also certified by Germanischer Lloyd with regard to corrosion resistance. Due to the variety of available products, SKF MonoFlex single-line distributors can be used in numerous applications, including machine tools and the wind, print, textile, and vehicle and construction industries.

SKF MonoFlex single-line distributors Description of functional types Introduction Prelubrication distributor On SKF MonoFlex single-line distributors designed as prelubrication distributors, the quantity of lubricant is fed to the lubrication point while pressure is being built up in the main line, i.e., during the lubrication unit’s run time. On prelubrication distributors, the expelling pressure can be set so it is approximately equal to the maximum permissible pressure of the pressure regulating valve on the lubrication unit. After the lubrication unit is switched on, the lubricant is...

SKF MonoFlex single-line distributors Description of functional types Relubrication distributor Main line Area of application Relubrication distributors are used in applications where an excessively high and sudden pressure at the lubrication point is undesirable, for example, when lubricating slideways on grinding machines. Such pressure at the lubrication point can lead to undesirable rough grinding results. The expelling time of the relubrication distributor depends on the back pressures in the lubrication point lines. If, for example, the lubrication points are under heavy load during...

SKF MonoFlex single-line distributors Description of functional types Area of application Dynamic distributors are used in applications where the lubricant needs to be delivered to the lubrication point almost immediately. An important application for dynamic distributors is the lubrication of chains in machinery and conveyor belts. Dynamic distributor On SKF MonoFlex single-line distributors designed as dynamic distributors, the quantity of lubricant is fed to the lubrication point while pressure is being built up in the main line, i.e., during the lubrication unit’s run time.

SKF MonoFlex system structure Prelubrication, relubrication, and dynamic distributor system SKF MonoFlex single-line centralized lubrication systems with single-line distributors generally consist of a lubrication unit, the single-line distributors, and the lubrication lines. The pressure regulating valve and pressure relief valve required for the singleline centralized lubrication system’s operation are normally integrated into the lubrication unit. If pressure losses of greater than 10 bar are expected in the single-line centralized lubrication system, for example due to expansion of the...

SKF MonoFlex system structure Important notes Fig. 1 WARNING Leaking lubricant is hazardous due to the risk of slipping and injury. Before using the equipment, fix any system where lubricant is leaking during assembly, operation, maintenance, and repair. Lubricants can contaminate soil and bodies of water. Lubricants must be used and disposed of properly. Observe the local regulations and laws regarding the disposal of lubricants. Lubrication point The lubrication line system also needs to be protected from excessive pressure by means of a pressure-limiting valve that is mounted separately...
