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.

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.

To obtain best results from any style of piston cup, it is recommended that the piston properly support the heel of the cup. Recommended diametral clearance between the piston and cylinder wall are as follows:
1" to 2-1/4" .005"
2-1/2" to 4-3/4" .008"
5" to 10" .010"
The height of the machined shoulder most frequently used to control squeeze on the heel of the cup is as follows:
Cups 1/8" thick .116/.119"
Cups 5/32" thick .146/.149"
Cups 3/16" thick .178/.181"
The follower plate should be approximately .110" smaller than the ID of the cup. To reduce any tendency of the cup to extrude under pressure a phonograph finish may be machined on the surface of the follower plate.
NOTE: The 8000 piston cups are center punched.

A homogeneous ring may be also used for sealing at low pressure. Do not include the homogeneous ring in calculating pressure rating. Due to the different material, it is difficult to rate this type of ring. If you wish to use all homogeneous rings, tests should be conducted to verify design stability.
