Main types of lining rings
1. Metal lined ring
The materials include copper alloy, bronze castings, bearing steel, etc., suitable for high load and high wear resistance scenarios.
The T-shaped lining ring adopts a shoulder design to enhance fixation; The P-type lining ring is quickly installed through an elastic retaining ring.
2. Non metallic/polymer lined ring
Such as nylon, rubber, TPE, etc., with soft texture, suitable for vibration reduction, noise reduction or human contact scenarios.
3. Oil free self-lubricating liner ring
Using self-lubricating materials, no additional lubrication is required, suitable for low maintenance and low friction scenarios.
Core selection methods
1. Clarify the working condition requirements
Load and speed: It is necessary to calculate the pressure, speed, and their product to ensure that the bearing limit of the lining ring is not exceeded.
Environmental conditions: High temperature and corrosive environments require the selection of materials that are resistant to temperature and corrosion.
2. Material matching
Selecting high hardness metals for heavy-duty low-speed scenarios; Low friction resin or copper alloy can be selected for light load high-speed scenarios.
When rust prevention is required, priority should be given to surface treatment with electroless nickel plating.
3. Lubrication and maintenance requirements
Oil free self-lubricating ring can reduce maintenance costs, but it is necessary to ensure that the lubrication conditions match the material properties.
4. Structure and size adaptation
The inner diameter needs to be accurately matched with the shaft; Special structures need to consider installation convenience and stability.
5. Suppliers and cost-effectiveness
Prioritize choosing brands or suppliers with stable quality and high precision, balancing performance and cost.
Selection precautions
Surface treatment: Smooth surfaces and neat edges can reduce friction losses.
Load properties: For dynamic loads, anti fatigue materials should be selected; Static loads can relax the material hardness requirements.
Lifetime verification: Estimate the service life through load calculation and simulation testing.
Through the above methods, it is possible to efficiently select the appropriate type of liner ring for specific application scenarios.
