Advantage

Industrial grade flat sliding bearings provide core guarantee for stable operation of equipment - achieving a win-win situation for production efficiency and cost control!

We use high-strength composite materials and precision manufacturing processes to create flat sliding bearings, which have three core advantages:

Super strong load-bearing performance - the special alloy matrix can withstand more than 30% additional load, ensuring long-term stable operation of heavy-duty equipment
Intelligent lubrication design - patented self-lubricating layer reduces friction coefficient to 0.08 and energy consumption by more than 20%
Long term durability characteristics - with a wear life of over 8000 hours, it maintains excellent performance even under extreme working conditions

Typical Application Scenarios

Metallurgical equipment: high temperature and heavy load environments such as rolling mills and continuous casting machines
Chemical machinery: corrosive media such as reaction vessels, centrifugal pumps, etc
Energy equipment: wind power variable pitch system, turbine guide vane mechanism

Technical Parameters

Rameter Category	Specific Parameters and Explanations
Structural Parameters	- Bearing Diameter: Determines the load-bearing area, commonly ranging from 50-500mm, matched to the equipment shaft diameter. - Bearing Width: Affects load capacity and friction power consumption; the width-diameter ratio (width/diameter) is typically 0.5-1.5. - Oil Groove Design: Includes the number and shape of axial/circumferential oil grooves (e.g., rectangular/spiral), influencing lubrication efficiency.
Material Parameters	- Bearing Alloy Materials: - Babbitt Metal (tin-based/lead-based): Wear-resistant and corrosion-resistant, suitable for medium-low speed heavy loads. - Copper Alloy: High hardness, ideal for high-temperature conditions. - Polymer Materials: Self-lubricating, used in water-lubricated or oil-free environments. - Backing Material: Steel/cast iron, providing structural support with bonding strength ≥200MPa.
Performance Parameters	- Load Capacity: - Static Load: Maximum allowable pressure 10-30MPa (metal bearings), 2-10MPa (polymer bearings). - Dynamic Load: Affected by rotational speed; oil film pressure increases with speed. - Friction Coefficient: - Hydrodynamic Friction: 0.001-0.008. - Boundary Friction: 0.01-0.1. - Operating Temperature Range: Metal bearings -20℃~120℃ (special alloys up to >200℃); polymer bearings ≤80℃.
Lubrication Parameters	- Lubricant Viscosity: - Mineral Oil: Viscosity at 40℃: 10-100cSt (low viscosity for high speed, high viscosity for heavy load). - Synthetic Oil: Suitable for extreme temperature conditions. - Oil Supply Pressure: Forced lubrication systems: 0.1-0.5MPa; hydrostatic bearings require 1-10MPa high-pressure oil. - Oil Film Thickness: Typical 5-50μm, must exceed the sum of surface roughness (Ra≤1.6μm).
Precision Parameters	- Surface Roughness: Bearing working surface Ra≤0.8μm; journal surface Ra≤0.4μm. - Fit Clearance: - Radial Clearance: 0.001-0.003×diameter (metal bearings), 0.003-0.005×diameter (polymer bearings). - Parallelism: ≤0.02mm per 100mm length. - Roundness & Cylindricity: Journal roundness ≤0.01mm; bearing bore cylindricity ≤0.015mm.
Operating Parameters	- Speed Range: - Metal Bearings: Conventional ≤5000rpm (high-speed types >10000rpm). - Hydrostatic Bearings: Form oil film at zero speed. - Working Medium: Lubricating oil, water, gas (gas hydrostatic bearings); consider medium corrosion. - Environmental Conditions: Humidity ≤90%, dust concentration ≤50mg/m³; special seals for dusty/watery environments.
Installation & Maintenance	- Installation Tolerance: Horizontal level ≤0.05mm/m; alignment deviation ≤0.03mm/m. - Maintenance Indicators: Oil contamination (particle size >50μm), temperature rise >40℃ above ambient, abnormal vibration (amplitude >0.05mm). - Service Life: Metal bearings 8000-15000 hours (depends on load); polymer bearings 5000-10000 hours.
