| 1) | Speeds of up to 5 m/s possible. Service life is limited by heightened wear to plastic parts. Tests have shown total travel from 50 • 105 m to 100 • 105 m without failure. |
| 2) | Frictional drags generated by Linear Bushings with integrated wiper seals on two sides when not under radial load. The frictional drags depend on speed and lubrication. |
| 3) | Clamped (fastened). |

| The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the values in the table need to be multiplied by 1.26. |

Impact of load direction on load rating of open Linear Bushings
The load ratings C and C0 apply for the main direction of loading ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fρ (dynamic load rating C) or fρ0 (static load rating C0).
Installing specific Linear Bushings can prevent reductions in load capacity (see Linear Set with side opening).
Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

Project planning information
Life expectancy calculation
Mounting
Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The adjustable Linear Sets come clamped to an h5 shaft (lower limit) and set to zero clearance.
Vertical dimension
The tolerance values for the vertical dimension "H" for the Linear Sets shown in the table have been determined from statistics and correspond to values expected in practice.
Bolts
We recommend bolts in accordance with ISO 4762-8.8 for fastening the Linear Sets.
Lubrication
On-shaft relubrication on relubricatable Linear Bushing only until lubricant seeps out.
