TEX BUSHING Sleeve Bushing Specification

A fabric bearing bushing is a specific type of bearing that utilizes a layer of fabric, often impregnated with a type of lubricant or other materials, to reduce friction between two surfaces. This fabric layer, when compressed and impregnated with lubricant, allows for smoother operation and lower friction.

Fabric bearing bushings are typically used in applications where there are high levels of vibration, impact, or variable loads. These bushings can be found in various mechanical and industrial applications such as automotive, aerospace, marine, and manufacturing machinery.

The fabric materials used for these bushings can vary, with each offering different properties that can enhance the performance of the bushing in specific applications. Some commonly used materials include polytetrafluoroethylene (PTFE), nylon, and various polyester fabrics.

The primary advantages of using a fabric bearing bushing include:

1. Self-Lubrication: These bushings often come impregnated with lubricant, meaning they can operate effectively without the need for additional lubrication. This can greatly extend the service life of the bushing and the machinery in which it’s installed.
2. Durability: Due to their ability to absorb vibration and resist wear, these types of bushings can be very durable and long-lasting, especially in harsh operating conditions.
3. Versatility: Fabric bearing bushings can be designed to fit a wide range of applications, with different materials offering different properties to suit various needs.

Despite these advantages, there are also certain limitations associated with fabric bearing bushings. For instance, they may not be as suitable for extremely high-speed applications, as the friction can generate excess heat. They also may not perform as well in very high or low-temperature environments, depending on the type of fabric and lubricant used.

TEX BUSHING
The material is made of various high quality metals with PTFE and other additives on the surface. This kind of material structure has higher bearing capacity and longer service life than ordinary three-layer composite materials. Substrate can be low carbon steel, stainless steel, copper. Used in agricultural machinery, construction machinery, automobile chassis parts, ball valves, butterfly valves, pumps and chemical industry and other heavy-duty low speed and unable to refuel occasions. The substrate is made of stainless steel 316, American harts INCONEL 625, 254SMO, S31803 (F51), etc.

TEX BUSHING Product introduction

Sliding bearing is a novel formula product designed according to the special working condition of reciprocating motion on the basis of self-lubricating material. Its performance is similar to DD2 abroad. It has the advantages of strong self-lubricating ability, good wear resistance, clear oil film and so on under the condition of oil failure. At present, the product has been widely used in automotive shock absorbers, motorcycle shock absorbers, various hydraulic cylinders, hydraulic motors, pneumatic components and other fields.

Metal composite series self-lubricating bearings

The SPLIT TYPE series metal composite self-lubricating materials for high quality low carbon steel substrate, sintering porous spherical copper powder layer, the surface of copper is given priority to with PTFE wear-resistant lubricating materials as bearing layer, the material has excellent mechanical bearing capacity, the middle copper powder layer can not only transfer the heat generated by the bearing during operation in time, but also improves the bonding strength of the plastic layer and the substrate. PTFE is designed for complete dry friction, and a variety of materials have been developed according to lubrication, friction coefficient and durability requirements. VIIPLUS’s PTFE metal composites provide the best performance in the widest range of loads, speeds and temperatures with or without external lubrication.

Bushing Bearing characteristics

The so-called oil-free means that there is no need to add oil or less oil. The goal of our research is to ensure that the bearing can still perform well under such conditions and extend its service life as much as possible. Self-lubricating bearing is the basic working principle of solid lubricant on the surface of the bearing in the early operational stage due to the friction of ask each other to form a transfer film and coat the to eventually form solid lubrication film on the grinding parts to achieve the purpose of self lubrication, which partition the direct contact between the workpiece and good protection of grinding extend the service life of the bearing and artifacts.
