Spring & 'O' ring materials Spring material Our spring energised seals are available with the following spring energisers. These materials are compatible with most media. Other spring materials are available but may require minimum production quantities. Other elastomer compounds are available to suit special applications/media; please consult us for technical advice.

When the Uni-Seal is seated in the gland, the spring is under compression forcing the jacket against the hardware. The spring compensates for jacket wear and eccentricity. The system pressure assists the spring pressure. The spring load can be tailored to meet special low friction requirements in dynamic applications, and loading can be increased for cryogenic sealing.

Maximum recommended diametral extrusion gap When sealing high pressure and/or temperature the clearance between the hardware Extrusion gap becomes very important. t high pressure and /or temperature the jacket material can extrude into the gap causing premature sealing failure. The extrusion gap should be held to the minimum practical or should not exceed above values. ack-up rings are manufactured of a harder material than the seal material. Surface finishes and hardness Dynamic The quality of the surface finish influences the relative wear of the cover material. The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life. Relatively rough finishes wear the cover material too rapidly, whereas too smooth surfaces result in insufficient material transfer to form a thin film. s general rule, the higher the sealing surface hardness the better the seal performance. igher hardness reduces wear and increases seal life. 40 R or higher is recommended for slow to moderate movements. Static Ensure that the seal's counterfaces are free from scores and spiral machining marks.

Wear rings J80 - J81 Types J80 and J81 J80xx Tape J81xx Rings Installation dimensions R max 0.2 o 20 J80xx Tape J81xx Rings o Z R max 0.2 D Z o 20 Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur. They also prevent metal to metal contact between sliding parts. Wear rings are available in tape or machined rings. o n important advantage is that metallic seizure cannot occur with the correct design. The most frequently used non-metallic wear ring Z materials are filled PTFE and compounds of PTFE and fabric materials. Z Wear rings are fitted easily into closed grooves on the piston or in the gland. The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material Din addition to the length of stroke, the diameter and other design factors. dvantage: Very good anti-friction behaviour No stick-slip effect Good dry running characteristics Good wear resistance with long service life.

The wear rings can be used in all hydraulic oil media. PTFE materials have a low coefficient of friction but also low load caracteristics. They are therefore better used for low load applications. Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications. uts Wear rings are made with different cuts 30 30 X- ut For reciprocating movement P P Y- ut For rotary movement W T T Z- ut For reciprocating or rotary movements in contaminated systems to protect the seal In extremely contaminated systems, consideration should be given to the use of ode 0 material in-board of one of our seals, with other wear ring materials in the out-board position. 20 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz
