Radial LB, 80, without seal Product Description radial linear bushing Shaft diameter d = 80 Without seal High-precision linear bushing for moving very heavy loads Radial ball redirection allows numerous rows of balls and extremely high load ratings Heavy-duty guide with degrees of freedom in circumferential direction For applications where other linear guides tend to warp due to imprecise substructures. Very high rigidity Extra smooth running Fully sealed or without wiper seals Separate wiper seals optional Relubricatable Hardened and machined steel sleeve Ball retainer made of reinforced PA Balls made of rolling bearing steel Two retaining rings Technical Specs Product attributes Shaft diameter d [mm] 80 Version Standard Format of linear bushings O - Open Series Radial Seal without wiper seals Lubrication Not lubricated Dynamic load capacity C [N] 54800 Note: dynamic load capacity C The stated load capacities apply for the main direction of loading ρ = 0°.
