When specifying sleeve bushings for gate, globe, and check valves, it is crucial to consider the appropriate size and material to ensure optimal performance and durability. PTFE (Polytetrafluoroethylene), also known as Teflon, is a commonly used coating material for valve bushings due to its excellent properties such as low friction, chemical resistance, and temperature tolerance.

The sleeve bushing size should be determined based on the specific valve dimensions and operating conditions. It is essential to ensure that the bushing fits tightly within the valve body to prevent leakage and wear. The PTFE coating provides an additional layer of protection and lubrication, reducing friction and wear on the bushing surface.

For gate, globe, and check valves, the sleeve bushing size typically corresponds to the valve's seat diameter or valve trim size. Manufacturers often provide standard bushing sizes for different valve sizes and types, but custom sizes can also be fabricated to meet specific requirements.

When selecting a PTFE-coated sleeve bushing, it is important to consider the coating thickness and quality. A thicker coating may provide better protection but can also increase the overall size of the bushing. The coating should be evenly applied and free of defects to ensure maximum durability and performance.

In summary, when specifying sleeve bushings for gate, globe, and check valves with PTFE coating, it is essential to consider the valve size, operating conditions, and coating requirements to ensure a reliable and long-lasting solution.

SELF-LUBRICATING BEARINGS GLEITLAGERBUCHSEN SOLUTIONS

Viiplus range of PTFE lined wrapped bearings is suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.
Our PTFE lined wrapped bearings have been developed for high duty, oil lubricate applications.
We are able to offer PTFE lined wrapped bearings in metric plain, imperial plain, metric flanged, metric washers, imperial washers, metric strip and imperial strip. Special sizes can be produced to customer requirements.
A self-lubricating bearing is a metallic component permeated in a lubricant oil. The oil provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. VIIPLUS Specialty Bearings features high performance, low wear self-lubricating bearing solutions.

METAL POLYMER COMPOSITE BEARINGS

Metal-polymer composite plain bearings enable economical solutions in many industrial and automotive applications. They are particularly effective with oscillating movements and achieve a rating life several times higher than that of bearings with conventional materials. In addition, all our new plain bearings are lead-free and, therefore, environmentally friendly.

self-lubricating bearing materials are based on specially engineered liner fabrics with a tight woven fabric of synthetic fibers coated / saturated with a unique matrix of PTFE powder, high strength resin, and special fillers. This design provides high load rating, uniform wear behavior, low friction and extended service life.

Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE

·Bushing material suitable for lubricated applications

·Self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

·Anti-friction bearing suitable for linear, oscillating and rotating movements

Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
 

STRUCTURE AND COMPOSITION

1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
