Stainless steel fabric bushings,this kind of bushings widely used in valve,oil, chemistry, metallurgy.It has flexible bearings, no maintenance, low installation accuracy, good shock absorption and impact resistance. Low noise characteristics, and due to the high strength of the fiber material and the support of the steel back, it has the unique advantage of high load capacity. In general sports, it is advisable to maintain proper clearance between the inner hole and the shaft. The size of the gap can be referred to the DU type product. The outer diameter of the bearing and the seat hole are generally interference fit. The interference can also be referred to the DU type product.

Metal matrix fabric composite sheet has more flexibility than general rigid bearings due to the 0.25mm thickness of fiber cloth lubrication layer. In some low-speed rocking motions, the bearing inner hole and the pin shaft can be used without gaps or even interference. Cooperate, this can better exert its shock absorption and low noise performance; such bearings are mainly used in low-speed, heavy-duty oil and grease lubrication, and can also be used in oil-free lubrication.

 

1. Press both upper and lower bearings into the valve body.
2. Install lower stem packing and lower spacer. Install cover plate with cap screws and washers.
3. Install upper bushing, upper packing, and upper spacer into valve body top stem hole.
4. Install packing retaining ring onto groove on valve stem.
5. Install disc into valve seat. This will require that a lubricant such as silicone oil or grease be
applied to the stem hub areas of both the disc and seat.
6. Install stem into valve body top stem hole (operator top plate side). The stem should be
installed so that its milled flat aligns with the disc torque plug hole.
7. Torque the plug down through the disc and against the milled flat on the stem.

TEX bearing use the PTFE fibres fabric and aramid fiber overlay on metal backings,the fabric have very high load capacity and high accuracygood run with low speed and heavy friction superior performance

 

Polytetrafluoroethylene fiber PTFE/Kevlar

 

 

 VIIPLUS TEX ptfe fiber metal base self-lubricating bearing is a self-lubricating composite bearing material made of high-quality low-carbon steel plate, bronze plate or stainless steel plate as the matrix, with the woven fabric of ptfe fiber as the friction surface layer.

The two are rolled into sliding bearing by means of a solid bond of structural adhesive.In order to guarantee the bonding strength between ptfe fiber and metal sheet, the woven fabric is made of special ptfe filament and aramid filament.

The bearing has the characteristics of high bearing capacity, good wear resistance, suitable temperature, wide range of medium, simple structure, compact size and good stability.

 


Polytetrafluoroethylene (ptfe) is a kind of self-lubricating material with excellent performance.But the wear resistance is poor because of the low strength.At present, most of the fibers or other fillers are used to improve the wear resistance, the effect is very limited.And polytetrafluoroethylene fiber has tensile strength 15 times higher than pure polytetrafluoroethylene resin, to make up for the lack of this aspect, wear resistance is greatly improved, at the same time, the fiber also avoids the occurrence of cold flow phenomenon of polytetrafluoroethylene resin.
Polytetrafluoroethylene fiber metal base self-lubricating bearings are divided into steel base, copper base and stainless steel base three.

Preparation and Properties of ptfe fiber braided Self-lubricating Composites

 

Polytetrafluoroethylene (PTFE) fiber fabric self-lubricating composite material is a new kind of solid self-lubricating material,PTFE fiber fabric retains the low friction coefficient of PTFE material at the same time, and has a high mechanical strength.Therefore, as the lubrication layer between the inner and outer rings of joint bearing, it is widely used in aerospace, automobile, large machinery and other fields.In this paper, PTFE fiber and Kevlar fiber were used as raw materials to weave PTFE fiber fabric by weaving machine. After the surface treatment of sodium naphthalene complexate solution, the self-lubricating composite material of PTFE fiber fabric was prepared by phenol-epoxy adhesive and bonding curing treatment of 45# steel.The friction coefficient and wear amount of PTFE fiber and the effect of surface treatment on the friction properties of composites were measured by friction and wear testing machine.The friction surface was characterized by scanning electron microscopy and the friction mechanism was analyzed.The interlining materials of woven fabric and finished fabric are compared and analyzed.The results show that the surface treatment with sodium naphthalene complex solution can strip the F element from the surface of PTFE fiber fabric, enhance its bonding strength with metal, but also reduce the wear resistance of PTFE fiber fabric to a certain extent.And the shorter the surface treatment time is, the smaller the reduction of wear resistance will be.In addition, the surface treatment of sodium naphthalene complex solution has little effect on aramid fiber and Kevlar fiber.After surface treatment for 5min, the friction surface of the sample produced more debris and abrasive wear.The higher the content of PTFE fiber in the self-woven fabric, the better the anti-wear performance of the fabric. For the fabric with 30% fiber content, the higher the friction speed is, the higher the friction coefficient is.On the contrary, for fabrics with 80% PTFE fiber content, the higher the friction speed, the lower the friction coefficient.
