Product description
Linear Sets with Standard Linear Bushings with a side opening. If the load is exerted counter to the direction of opening with open Linear Bushings, this will result in a reduction in load capacity. In order to prevent this and facilitate the installation of specific Linear Bushings, Linear Sets with a side opening have been developed.

| 1) | The load ratings apply for the main direction of loading. |
| 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. |

For load in the direction of opening, please refer to the loading diagrams (see "Diagrams" section).
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).

Life expectancy calculation
Mounting
See the notes on installing Linear Sets with side opening.
Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The R1066, R1068 and R1072 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.
General mounting instructions
Commissioning
Linear sets with standard Linear Bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
