What is the Bosch Rexroth R067202000?

Super linear bushing

Super B (no self-alignment feature)

Closed

Shaft diameter d = 20

Without seal

Low-cost linear bushing for high requirements

Steel bearing plates with machined ball guide grooves and optimized ball lead-in chamfers for outstandingly smooth travel and a long service life

Without self-alignment feature for transferring lower tipping force along the axial direction

High travel speed (5 m/s)

Integrated wiper seals, external seals or no wiper seals

Ball retainer and outer sleeve made of PA or POM

Balls made of rolling bearing steel

No initial lubrication

Specifications

Shaft diameter d [mm]	20.0
Version	Standard
Format of linear bushings	– Closed
Series	Super B (no self-alignment feature)
Type	Linear bushing
Seal	Without wiper seals
Lubrication	Not lubricated
Maximum dynamic load capacity Cmax [N]	2470.0
Maximum acceleration rate amax [m/s²]	150.0
Maximum permissible linear speed vmax [m/s]	3.0
Note: maximum permissible speed vmax	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 • 10<sup>5</sup> m to 100 • 10<sup>5</sup> m without failure.
Length of linear bushing [mm]	45.0
Outer diameter D [mm]	32.0
Permissible ambient temperature (min. ... max.)	-10 °C ... +80 °C
Friction coefficient μ	0.001 ... 0.0025
Note: friction coefficient μ	Friction coefficients of unsealed linear bushings when lubricated with oil. The friction coefficient is lowest under heavy load, but can still be above the specified value even under a low load.
Weight [kg]	0.07
Footnote breakaway force	One wiper seal: Multiply value with factor 0.5
Footnote maximum dynamic load capacity Cmax	The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
Footnote minimum dynamic load capacity Cmin	The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
Footnote friction force FR	1. One wiper seal: Multiply value with factor 0.5 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.
Breakaway force [N]	3
Dimension C h13 [mm]	45
Dimension C1 H13 [mm]	31.2
Dimension C2 [mm]	1.6
Dimension D [mm]	32
Dimension D1 [mm]	30.5
