SAE 430B Bearings Lubrication Solutions: Grease Grooves vs. Solid Lubricant
We offer two primary lubrication configurations to match your maintenance requirements:
1. Traditional Grease Groove Design
For systems with regular maintenance schedules, we machine precise oil/grease grooves to ensure uniform lubricant distribution.
-
Groove Styles: Loop, Double Loop, Figure-8, Straight, or Circular.
-
Benefit: Cost-effective solution for accessible machinery.
2. Maintenance-Free Solid Lubricant (Plugged Graphite)
For hard-to-reach areas or applications where oil contamination is prohibited, we embed solid graphite plugs into the C86300 matrix.
-
Mechanism: During operation, a friction film is created, separating the shaft from the bearing.
Benefits:
- Self-lubricating (Oil-less operation).
- High temperature resistance.
- Reduced maintenance costs and downtime.
- Excellent start-stop performance.
C86300 Manganese Bronze Wear Plate for Bridge Expansion Bearings
Bridge bearings, structural components between the substructure and superstructure, transfer imposed loads and accommodate slight movements using C86300 bronze wear plates. These bearings manage rotational, translational, horizontal, and transverse movements, mitigating stress. C86300 manganese bronze (ASTM B22), selected for its high tensile (110ksi) and yield strength (62ksi), withstands heavy loads and slow movements. Integrated solid lubricant graphite plugs provide self-lubrication and eliminate maintenance.
-
Q: Can C86300 be used without lubrication?
-
A: Standard C86300 requires grease/oil. However, our C86300 with Graphite Plugs is designed for oil-less, self-lubricating operation.
-
-
Q: What is the maximum operating temperature for C86300?
-
A: It maintains properties well up to 500°F (260°C), especially when equipped with high-temp solid lubricants.
-
-
Q: Do you require a minimum order quantity (MOQ)?
-
A: We support both prototype runs and high-volume production. Contact us for specifics.
