Composite bearings use guide: Professional maintenance and life enhancement points
I. Core advantages
- composite bearings (bimetallic oil-free bearings) with mild steel as the substrate, the surface of the sintered lead-tin-bronze alloy, both:
- high load-bearing capacity: for heavy loads, low-speed, reciprocating or oscillating conditions;
- high-temperature/corrosion resistance: no fear of acid flushing or flooded environments;
- self-lubricating characteristics: friction surface can be customized oil groove/oil holes, adapted to different lubrication needs.
Key Precautions for Use
- Strict Dust Protection
- Even the slightest dust will aggravate the wear and tear, keep the installation environment clean (compressed air blowing is recommended).
Standardized installation operation
- Prohibit hammering or strong stamping to avoid deformation of the rolling element;
- Use special tools (such as hydraulic mounting device), and strictly prohibit the use of cloth or short-fiber materials to contact the bearings.
Rust prevention
- Wash hands and apply mineral oil before operation, increase the frequency of applying rust prevention oil during rainy season/summer;
- For long-term storage: place horizontally, segregate chemicals, and use equidistant wooden spacers to separate multiple layers of stacking.
Optimized for special conditions
Under light load conditions, life can be significantly extended by forming a complete lubricant film (ideally up to "permanent life").
Storage and Maintenance Standards
Environmental Requirements: dry and ventilated, placed horizontally, and isolated from corrosive substances;
Overdue treatment: re-cleaned and coated with antirust oil after the rust prevention period;
Stacking Specifications: consistent position of pads in each layer when storing in multiple layers, to avoid localized stress concentration.
Typical Application Scenarios
- Heavy-duty vehicle balance axle bushings, engine/chassis components, motorcycle clutches, gear pump wipers and lifting equipment, etc. They are especially suitable for medium-speed medium-load or low-speed high-load scenarios.
Professional tips: Regularly check the bearing clearance and lubrication status, and adjust the maintenance cycle with the working conditions to maximize the performance advantages of composite bearings.
