Types of plain bearings
Types of plain bearings are used in various industries and applications to provide low friction and smooth motion between moving parts. They offer a cost-effective and low-maintenance solution compared to more complex bearing systems. Main Characteristics:
Self-lubricating and maintenance-free bearings are ready to install and perfectly suited for lower sliding speeds. They have low wear and a low friction coefficient, preventing stick-slip issues. These bearings are ideal for circular, swiveling, and partially axial movements. They can handle extremely high bearing loads, do not absorb moisture, and exhibit high corrosion resistance.
Bushing Construction:
These bearings are constructed with a tin-plated steel back (including edges) to provide strength and corrosion resistance. A multi-porous bronze layer is sintered onto the steel back, which serves as a base for the sliding surface. The sliding surface is made of a PTFE-lead compound, which ensures low friction and self-lubricating properties.
In summary, these self-lubricating and maintenance-free bearings are designed for easy installation and long-lasting performance in various applications. Their low friction and wear characteristics make them suitable for a range of motion types, while their robust construction ensures high load capacity and corrosion resistance.
Browse Bushing Surface:
The surface of these bearings is tin-plated and PTFE-coated, providing excellent corrosion resistance and low friction properties. These bearings are available in both inch and metric sizes to suit various applications.
Recommended Mounting Tolerances:
For optimal performance, it is crucial to follow the recommended mounting tolerances. The housing bore should have an H7 tolerance, while the shaft tolerance should be as follows:
- For shaft diameters up to 55mm (or equivalent in inches), use an f7 tolerance.
- For shaft diameters above 55mm (or equivalent in inches), use an h8 tolerance.
By adhering to these mounting tolerances, you can ensure proper fit and performance of the bearings in their respective applications.

Cylindrical and slotted bushes are crucial components used in the manufacturing process to enhance efficiency, minimize downtime, and ensure the quality of finished products.
Cylindrical bushes are hollow tubes with a smooth, uniform exterior surface that are typically used to reduce friction between two moving parts. They are commonly utilized in machines where the movement of one component may cause wear or damage to another. Cylindrical bushes act as a buffer between these parts, absorbing shock and minimizing the impact of movement. This helps to prolong the life of the machine, reduce maintenance requirements, and prevent costly repairs.
On the other hand, slotted bushes have a groove running along their length, which makes them particularly useful for applications where axial movement is required. The groove allows for the movement of the shaft or component, while still maintaining a snug fit to prevent lateral movement. This results in more precise and accurate positioning of parts, which is essential in manufacturing operations where even small deviations from tolerances can cause significant problems.
Overall, the use of cylindrical and slotted bushes in manufacturing is crucial for optimizing production processes, reducing downtime, and ensuring product quality. By reducing wear and tear on machine components, these bushes can help extend the lifespan of equipment and minimize the need for repairs or replacements. Furthermore, their ability to maintain precise positioning and prevent lateral movement can improve the accuracy and consistency of manufacturing operations, leading to higher-quality products and greater customer satisfaction.
