Kintowe DF054 double acting piston seal provides the designer with a compact, low friction seal for light to medium duty hydraulic cylinders. It comprises a PTFE face ring, strengthened with additives to resist creep, which is pre-loaded by an O-ring to be effective for the operating pressure range recommended. As the pressure rises the O-ring deforms and compresses the PTFE face ring against the tube wall increasing the sealing force and the effectiveness of the seal. As only the PTFE face ring is in contact with the sliding surface , friction is very low and stick-slip movement is eliminated. The housing width allows the designer to use a narrow width piston, but it is recommended an adequate bearing is mounted either side of the seal as shown. Different kinds of material options for PTFE face ring can be provide to extend operating conditions .

The S lip is the standard lip profile design. It offers redundant sealing surfaces with radiused contact areas for medium unit loading. This design feature provides the best combination of wear and seal ability , making the S lip suitable for the widest range of applications.

The A lip employs a large radius, and therefore low unit loading, resulting in low friction and low wear. This lip profile is recommended for applications with high surface speeds or those that require low friction. The profile also facilitates installation in glands with insufficient lead-in chamfers.

The B lip profile produces the highest unit loading of all of the lip profiles offered by Kintowe. The B lip is recommended for use in static applications and is required when the FanSaiSeal component diameter is less than 3/16” (4.7mm).

The C lip provides a flat sealing surface which allows for a constant wear rate over the life of the seal, making it ideal for rotary applications where extending seal life is the primary goal.

The D lip profile’s low unit loading characteristics offer long wear, with somewhat less effective sealing than higher unit loaded seals. This design is particularly well-suited for reciprocating applications.

The E lip profile is a radiused lip profile similar to the S lip, but with a single point of contact. This lip profile generates the lowest friction of any V-Spring FanSaiseal and has extremely high seal ability. This lip is best suited for static sealing applications and light oscillating applications where tight sealing is required.

The F lip features a profile suitable for systems contaminated with abrasives. Lower unit loadings offer extended seal life in rotary applications.

The J lip also has redundant sealing surfaces, with the sharp front edge protecting the secondary, radiused surface from abrasive media.Besides use in scraping applications, this lip is also used with step-cut glands and is the preferred profile for use with high-viscosity media.

The POLYESTER LUBRICATION series bearings (PFB) in Kintowe product series are continuously wound with glass fiber and epoxy resin material (bearing layer), filled with PTFE fiber and high strength fiber internal lubricant and high temperature epoxy resin as sliding layer, so as to form a natural concentric high strength bearing without joint and overlap This high-strength laminate structure allows bearing wall thickness of only (1.59mm-3.18mm), reducing product size and bearing weight during assembly such composite bearings exhibit extremely low friction coefficients and high bearing capacity

PFC-6 CharacteristicsKintowe PFC-6 is an ultra strong fiber reinforced composite material, with unique manufacturing process, PFC-6 has high compressive strength, high wear resistance and low friction performance. PFC-6 can adapt the complex operating conditions.PFC-22 CharacteristicsKintowe PFC-22 is an advanced, reinforced composite mate- rial contains solid lubricants. The material has exceptional wear resistance and virtually no swell in water, providing dimensional stability. PFC-22 tolerates edge loading and misalignment even with the heaviest loads.Kintowe Marine Bearings are installed with an interference fit. Bearings are normally freeze fitted using liquid nitrogen but can be press fitted or resin chocked as required.Where there are extended periods without lubrication, such as upper pintle bearings under light ballast conditions, Kintowe PFC-22 proves especially effective.

Spherical bearings are generally used for swing movement (ie angular movement) at lower speeds. Since the sliding surface is spherical, it can also be tilted within a certain angle range (ie self-aligning movement), and it can still work normally when the support shaft and the shaft shell hole are not at the same degree of eccentricity.The company's spherical bearings are processed from composite materials such as laminated phenolic or polyester resin laminated cloth. There is almost no electrochemical corrosion in seawater or other aqueous solutions, so they will not rust.
