Product Specification

Sleeve acetal plastic POM (Polyoxymethylene) plain bearings, also known as composite bushings, are widely used in various applications due to their excellent wear resistance, low friction, and good mechanical properties. When these bearings are grease-lubricated, their performance and lifespan can be significantly enhanced. Here’s a detailed overview:

Key Features of Sleeve Acetal Plastic POM Plain Bearings:
Material Properties:

Polyoxymethylene (POM): Known for its high stiffness, low friction, and excellent dimensional stability.

Composite Structure: Often combined with other materials to enhance properties like load capacity and wear resistance.

Grease Lubrication:

Reduced Friction: Grease helps in minimizing friction between the bearing and the shaft, leading to smoother operation.

Wear Protection: Lubrication reduces wear and tear, extending the bearing's lifespan.

Corrosion Prevention: Grease can provide a protective layer against moisture and contaminants.

Applications:

Automotive: Used in various components like suspension systems, steering linkages, and door mechanisms.

Industrial Machinery: Ideal for conveyor systems, agricultural equipment, and packaging machinery.

Consumer Electronics: Found in appliances and other devices requiring low-friction movement.

Advantages:

Self-Lubricating: Some POM bearings have self-lubricating properties, reducing the need for frequent maintenance.

Noise Reduction: Grease-lubricated bearings operate more quietly.

Load Capacity: Enhanced load-bearing capacity due to the composite structure and lubrication.

Maintenance:

Regular Lubrication: Periodic application of grease is necessary to maintain optimal performance.

Inspection: Regular checks for wear and tear to prevent unexpected failures.

Selection Criteria:
Load and Speed: Consider the operational load and speed to select the appropriate bearing.

Environmental Conditions: Factor in temperature, humidity, and exposure to chemicals.

Shaft Material: Ensure compatibility between the bearing and the shaft material to avoid excessive wear.

Installation Tips:
Proper Fit: Ensure the bearing fits snugly without excessive force.

Alignment: Proper alignment of the shaft and bearing is crucial to avoid uneven wear.

Lubrication: Apply grease evenly during installation to ensure smooth operation from the start.

Common Issues and Solutions:
Overheating: Often due to inadequate lubrication or excessive load. Ensure proper grease application and check load ratings.

Wear: Regular inspection and timely replacement of worn-out bearings can prevent machinery damage.

Noise: Unusual noises may indicate misalignment or insufficient lubrication. Re-align and re-lubricate as necessary.

Metal-Polymer Plain Bearings Grease Lubricated

POM is a triple layer bearing consisting of copperplated steel frame, a middle layer of sintered bronze and a sliding surface of acetal plastic (POM).The sliding surface is provided with grease pockets which embeds the lubricant for gradual
release during operation. The slip layer also has a good ability to embed dirt and small particles that could damage the shaft. POM can withstand relatively high loads and is suitable for rotary and oscillating movements and structures with frequent starts and stops.
