High-Burst-Pressure Flexible Grease Hose Assembly

Machines move, articulate, and vibrate. Rigid piping cannot bridge the gap between a stationary pump and a moving bearing on a robotic arm or an excavator bucket. The High-Burst-Pressure Flexible Grease Hose Assembly solves this. Constructed with a synthetic rubber inner tube, reinforced with layers of high-tensile steel wire braid, and covered in a weather-resistant jacket, these hoses deliver thick grease safely to moving components under extreme pressure.

Key Advantages & Benefits:

  • Handles Articulation: Designed to flex and move with machinery without fatiguing or breaking.
  • Extreme Pressure Ratings: Steel wire braiding allows the hose to withstand the massive spike pressures generated by heavy-duty grease pumps.
  • Custom Lengths & Fittings: Available pre-crimped in various lengths with a wide array of thread ends (JIC, BSP, NPT) to fit any system.
  • Weather and Wear Resistant: The tough outer cover resists UV rays, ozone, rock abrasions, and harsh chemicals.

Versatile Applications:

  • Articulating joints on construction machinery
  • Moving axes on large gantry CNC mills
  • Suspension points on commercial vehicles
  • Wind turbine blade pitch bearings

Frequently Asked Questions (FAQ):

  • Q: How do I know if the hose needs replacing? A: Hoses should be inspected regularly. Look for cracked outer covers, exposed steel braiding, blistering, or weeping of grease at the crimped joints. If any of these are present, replace immediately.
  • Q: Can I repair a damaged hose myself? A: No. High-pressure grease hoses must be professionally crimped using specialized hydraulic equipment. A DIY repair is a severe safety hazard under high pressure.

FAQ

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.
