Why Choose a Resistance Lubrication System?

Simple System Structure: A resistance lubrication system can use a relatively straightforward pump, main line, metering devices, and branch lines.

Controlled Oil Distribution: Resistance metering devices help regulate the amount of oil delivered to different lubrication points.

Suitable for Multiple Lubrication Points: Multiple bearings, guideways, gears, and other lubrication points can be connected to one centralized oil supply.

Flexible Metering

Different resistance values can be selected according to the lubrication requirements of individual points.

Easy System Integration

The system can be incorporated into machine tools and automated production equipment.

Reduced Manual Lubrication

Centralized oil distribution reduces the need for technicians to manually lubricate individual points.

Compact Configuration

The relatively simple distribution architecture can be suitable for machines where installation space is limited.

How Does a Resistance Lubrication System Work?

Oil Supply

The lubrication pump draws oil from the reservoir and supplies it to the main lubrication line.

System Pressurization

The pump creates the pressure required to move lubricant through the distribution network.

Flow Restriction

Resistance metering devices restrict the oil flow according to their individual resistance characteristics.

Lubricant Distribution

Oil passes through each metering device and is delivered to its connected lubrication point.

Lubrication Cycle

Depending on the system configuration, the pump can operate continuously, intermittently, or according to a preset lubrication schedule.

Flow Balancing

Metering resistance can be selected according to the required oil quantity of each lubrication point, helping distribute lubricant across the system.

Resistance vs. Positive Displacement Lubrication

Resistance and positive displacement systems both provide centralized lubrication, but their metering principles are different.

Feature	Resistance Lubrication	Positive Displacement Lubrication
Metering principle	Flow controlled by resistance	Mechanical displacement
Typical lubricant	Primarily lubricating oil	Oil or suitable grease, depending on system
System structure	Simple distribution network	Pump + positive displacement metering devices
Flow behavior	Influenced by system pressure and lubricant viscosity	Defined metering output
Individual point metering	Controlled through resistance selection	Predetermined displacement
Typical advantage	Simple and economical oil distribution	More defined individual lubricant quantity
Typical applications	Machine tools, industrial machinery, guideways	Industrial equipment, mobile equipment, multi-point lubrication

Resistance Lubrication System Components

01/

Oil Lubrication Pump: Supplies lubricant to the main line, controlled by timer, machine signal, PLC, or dedicated controller. Selection considers oil flow, system pressure, reservoir capacity, lubrication frequency, point count, oil viscosity, and operating temperature.

02/

Resistance Metering Units: Regulate oil flow to individual lubrication points. Different metering configurations can be selected per required lubricant quantity.

03/

Distribution Blocks: Organize multiple lubrication outlets and simplify system installation.

04/

Oil Tubing & Fittings: Connect pump, metering units, and lubrication points. Selection considers oil compatibility, working pressure, temperature, installation environment, tube length, and machine movement.

05/

Pressure Monitoring: Pressure switches and gauges monitor the system, helping maintenance personnel identify abnormal pressure and potential problems.

06/

Control Unit: A controller or timer determines the lubrication interval. For automated machinery, the system can be integrated with the machine control system where required.

Applications

Machine Tools: CNC machines, lathes, milling machines, grinding machines, machining centers, and automated machine tools. Resistance oil lubrication can be used for guideways, bearings, slides, and other components requiring controlled oil delivery.

Industrial Production Equipment: Production lines, automated machinery, packaging equipment, textile machinery, processing machinery, and material handling equipment. Centralized oil distribution simplifies lubrication maintenance across multiple machine points.

Guideway Lubrication: Machine guideways often require a controlled and regular supply of oil. Resistance systems distribute oil from a central reservoir to multiple guideways or sliding surfaces.

Bearing Lubrication: The system can be configured to supply oil to multiple bearings where continuous or intermittent lubrication is required.

Textile Machinery: High-speed textile equipment contains multiple bearings and moving components requiring regular oil lubrication. A centralized resistance system provides controlled oil supply while reducing manual lubrication requirements.

For machine manufacturers, resistance lubrication can be integrated into the equipment during the design stage.

We support OEM projects with

Lubrication point mapping, metering selection, pump selection, distribution layout, tubing and fitting configuration, reservoir selection, control configuration, and technical documentation.

Information Required for System Design

Machine model, number of lubrication points, lubrication point locations, lubricant specification, required oil quantity, lubrication frequency, operating temperature, existing lubrication system (if applicable), and machine drawing.

FAQ

Q: What is a resistance lubrication system?

A: A resistance lubrication system is a centralized lubrication system that uses resistance-type metering devices to regulate the flow of lubricating oil to multiple lubrication points.

Q: Can different lubrication points receive different amounts of oil?

A: Yes.Different resistance metering devices can be selected for different lubrication points so that the oil distribution can be adjusted according to individual lubrication requirements.

Q: Is a resistance system suitable for grease?

A: Resistance systems are primarily designed for oil lubrication.If your application requires grease, a positive displacement or progressive lubrication system may be more appropriate depending on the application.

Q: What is the difference between resistance and positive displacement lubrication?

A: A resistance system regulates oil flow through resistance, while a positive displacement system uses a mechanical metering mechanism to deliver a predetermined quantity of lubricant.Resistance systems are generally suitable when a simple centralized oil distribution solution is required.

Q: Can the system be integrated with a machine PLC?

A: Yes, where the pump and control configuration support the required interface.The lubrication controller can be configured to operate according to machine running status, preset lubrication intervals, or other control signals.

Q: Can you design a complete resistance lubrication system?

A: Yes.We can evaluate the pump, metering devices, distribution blocks, tubing, fittings, control requirements, and lubrication point layout for a complete centralized system.

Q: What is the MOQ?

A: Regular production and OEM order quantities can be discussed according to the product model and customization requirements.

Q: What payment methods do you accept?

A: For international orders, T/T bank transfer is generally accepted.A typical payment arrangement is:
30% deposit to start production
70% balance before shipment

Q: What is the lead time?

A: For standard products in regular production, the typical lead time is 7–15 working days after payment confirmation.For customized or OEM configurations, the typical lead time is 15–30 working days.

Q: How quickly can I receive a quotation?

A: For standard products with complete product information, we aim to provide a quotation within 1 business day.Customized system projects may require additional technical evaluation.
