What is the Bosch Rexroth R067121245?

Super linear bushing

Super A (with self-alignment feature)

Open

Shaft diameter d = 12

Fully sealed

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

Compensates for shaft deflection and misalignment up to 30'

Open linear bushing on fully supported shafts for applications where other linear guides tend to warp due to imprecise substructures.

High travel speed (5 m/s)

With longitudinal seal

No initial lubrication

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

Specifications

Shaft diameter d [mm]	12.0
Version	Standard
Format of linear bushings	O - Open
Series	Super A (with self-alignment feature)
Type	Linear bushing
Seal	Fully sealed
Lubrication	Not lubricated
Dynamic load capacity C [N]	1060.0
Note: dynamic load capacity C	The load capacities apply for the main direction of loading.
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.
