Component Specifications

Definition
The Grease Passage is an internal conduit system integrated into the Cross Spider component, designed to deliver controlled amounts of lubricant from a central reservoir to specific bearing points. It ensures consistent lubrication under operational loads, reducing friction and wear between moving parts.
Working Principle
Operates on pressure differential and capillary action principles. Lubricant is forced through the passage via a centralized grease fitting, flowing through machined channels to reach designated lubrication points on bearing surfaces.
Materials
Typically manufactured from hardened alloy steel (AISI 4140 or equivalent) or stainless steel (AISI 304/316) for corrosion resistance. Surface finish: Ra ≤ 1.6 μm.
Technical Parameters
  • Length 50-200 mm (machine-dependent)
  • Diameter 3-8 mm (standard)
  • Flow Rate 0.5-2.0 ml/min
  • Pressure Rating Up to 100 bar
  • Temperature Range -20°C to 150°C
Standards
ISO 4400, DIN 3405

Frequently Asked Questions

How often should grease passages be inspected?

Inspect every 500 operating hours or during scheduled maintenance. Check for blockages using pressure testing.

Can different grease types be used in the same passage?

No. Always use manufacturer-specified grease to prevent chemical incompatibility and channel blockage.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
