1)	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.
2)	Determined from working bore diameter and shaft tolerance statistics. When factoring in the outer diameter of the Linear Bushings and the housing bore, an h6 shaft produces similar radial clearance values as specified in the "H6H7" column under "Radial clearance" for the R0610 standard Linear Bushing.

1)	The load ratings indicated are minimal values as the orientation and direction of load cannot always be clearly defined.
	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 closed Linear Bushings

The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.

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 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.
