CUT seals are double-acting piston seals ( fig. 1 ) and have a step cut slide ring and a rectangular energizer. They are suitable for pressures up to 500 bar (7 250 psi) in heavy duty applications. CUT profiles are available in metric sizes and some fit seal housings in accordance with ISO 7425-1:1988. For additional information, refer to CUT profile data.
They also can be used for short pressure pulses and shock loads with proper system design. For additional information, contact SKF.

| Material codes | Slide ring: PA66/011 Energizer: N70/015 |
| Pressure | Up to 500 bar (7 250 psi) |
| Speed | Up to 1 m/s (3.2 ft/s) |
| Temperature range |  For temperature limits depending on fluid compatibility → see Engineering information |
 | Extreme low temperature range: may be intermittently exposed (e.g. cold start-up) without seal damage, but seal performance may be compromised while in this range |
 | Temperatures below the recommended operating range: seal performance depends on system design (precision guiding arrangement recommended) |
 | Recommended operating temperature range for this profile and material |
 | Temperatures above the recommended operating range: acceptable only with reduced pressure, speed, and/or e-gap |
 | Extreme high temperature range: only occasional short-term exposure (e.g. cylinder in curing oven of a powder coating process) |
| Dimension standards | Some sizes fit seal housings in accordance with ISO 7425-1:1988. |
| Counter-surface | → see Engineering information |

| Additional information | → Piston seals with rigid split slide rings |
| Maximum values of application parameters (e.g. pressure, speed, temperature, e-gap) should not be applied continuously nor simultaneously. | |
