What is the Bosch Rexroth R074220830?

Flange linear bushing

Standard (metal)

Central flanged

Shaft diameter d = 8

With two seals

Version: Rust-resistant

Rugged all-metal design with steel ball retainer for harsh environments and heavy contamination

Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life

For use in woodworking, foundries, cement plants

Stainless steel for the medical, chemistry and food industries

Integrated wiper seals

Pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming.

Hardened and machined outer sleeve made of stainless steel comparable to 1.4125

Ball retainer made of stainless steel comparable to 1.4301

Balls made of stainless steel comparable to 1.4125

Flange made of stainless steel comparable to 1.4006

Maximum permissible linear speed vmax [m/s]	2.5
Length of linear bushing [mm]	46.0
Outer diameter D [mm]	16.0
Permissible ambient temperature (min. ... max.)	-10 °C ... +80 °C
Note: permissible ambient temperature (min. ... max.)	Only unsealed linear bushings with steel ball retainers may be used at higher temperatures. Make allowance for reductions in load capacity.
Weight [kg]	0.06
Static longitudinal moment load capacity ML0 [Nm]	4.5
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 shaft radial clearance h6	Determined from working bore diameter and shaft tolerance statistics. Recommended housing bore tolerance: H6 or H7
Footnote friction force FR	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.
