Spring-Loaded Grease Cups

Spring-Loaded Grease Cup

Sometimes the best solution is the simplest one. The Mechanical Spring-Loaded Automatic Grease Cup offers a purely mechanical, low-cost method for continuously greasing a single bearing. Consisting of a transparent reservoir, a piston, and a heavy-duty compression spring, the cup is filled using a standard manual grease gun, which compresses the spring. As the machine operates, the spring slowly forces the piston down, constantly feeding grease into the bearing to replace what is consumed.

Key Advantages & Benefits:

Purely Mechanical: Contains no batteries, gas generators, or electronics, ensuring absolute reliability in harsh environments.
Infinitely Reusable: Simply attach a grease gun to the integrated zerk fitting and pump to refill the cup and reset the spring.
Transparent Housing: The clear polycarbonate body allows operators to instantly see the remaining grease level from a distance.
Highly Economical: The most cost-effective method for automating single-point lubrication on older or less critical machinery.

Versatile Applications:

Agricultural machinery pivots
Mining trommel screens
Light-duty conveyor bearings
Landscaping equipment

Frequently Asked Questions (FAQ):

Q: How do I control how fast the grease comes out? A: The flow rate is controlled by changing the tension spring (we offer light, medium, and heavy springs) and by adjusting a metering valve at the base of the cup to suit the bearing's demand.
Q: Can the spring break the bearing seal? A: No, the pressure generated by the spring is relatively low (typically 1-2 bar), which is just enough to feed the bearing as it rotates, without blowing out the bearing seals.

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation

Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.

Process Validation Before Mass Manufacturing

Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.

Integrated Heating and Degassing Process

The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
