Style 614 rod bearings are available in nylon material. These products are used extensively in hydraulic cylinders due to their low rate of wear and non-scoring properties. Excellent for those heavy duty applications that require a sturdy bearing. Most of these bearings are solid, although some may be split.

Manufactured using woven fabric-reinforced polyester resin, this material produces a dimensionally accurate rectangular strip which can be cut to any length. Low coefficient of friction and high compressive strength makes it an ideal bearing material. A common radial thickness of 1/8 in. allows the stacking of various widths. Size reference is marked every 6 in. on the strip. Available by the foot or rolls of 16 feet. Cutting is made easy by using Anvil type pruning shears. Wall tolerance ± .002 in., radial wall thickness = 0.124 to 0.121 in. Standard part numbers are gray in color.

These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible.

The PA Unitized Pistons are designed to handle a broad range of application parameters. The piston body is machined to exact dimensions and is constructed using four components: A high strength steel body, a non-metallic bearing, a rubber loading ring and a filled PTFE seal ring. The non-metallic bearing is molded to the piston using a special proprietary process.

INSTALLATION OF PTFE PISTON SEALS
Installing PTFE piston seals is not always an easy task. The use of installation tools (Designated by a 'CTC-' product code prefix) is recommended but often not convenient when working with a wide variety of sizes and applications. Finger installations are practical with rings of smaller cross-sections. Using fingers or a rounded plastic stick, knead the ring over the piston into the groove. With rings of larger cross-sections it may be necessary to heat the ring. Warming the ring in water or oil at 130° F or 140° F for about 5 minutes will soften the material for easier installation. Always avoid inconsistent stretching or overstretching of the PTFE seal.To prevent the PTFE ring from snapping into the wrong groove, cover wear ring grooves with plastic tape.
After seal installation, assembly of the cylinder may be difficult if the piston seal is loose on the piston or the cylinder has an inadequate leading edge chamfer. In such cases, compress the piston seal with belting or a suitable hose clamp. If the piston seal must pass threads or any other sharp edges during the cylinder assembly, cover the edges with plastic tape or wrap. Note: Caterpillar part number are used as a refernce only. We do not imply that these part are original equipment parts.
