- DESCRIPTION
S4 is a guide ring, intended for use in rod applications.
- ADVANTAGES
• Easy mounting
• Good dimension stability during operation temperatures
• Protection from hydrodynamic pressure due to diagonal cut
• Wide range of dimensions- MATERIAL
Polyamide Fiberglass filled PA+GF30
- APPLICATION
• Agricultural machinerys
• Construction machinery
• Material handling equipment
• Cylinders for industrial equipment with light and medium operating modes
• Standard cylinders- CONDITIONS
• Temperature:
-40°С ... +130°С
• Sliding speed:
up to 1.0 m/s
• Media:
mineral oils, water-oil emulsions- NOTES
At cylinders designing guide ring S4 should be placed in the place where it will have a direct contact with the media. S4 ring is not suitable for dry working conditions.

SURFACE ROUGHNESS Dynamic surface Ra ≤ 0.3 µm Rt ≤ 2.5 µm Static surface Ra ≤ 2.0 µm Rt ≤ 10.0 µm CHOICE OF GUIDE RING WIDTH A rough estimate of guide width can be calculated with the following formula: FН*k hmm ≥ pН/mm2 * dmm где: hmm - Guide ring width, mm FН - Radial load, N k - Safety factor (generally 2) dmm - Rod diameter, mm pН/mm2 - Static compressive strenght, N/mm2:
40 at 20°С
30 at 60°С
