INA high precision shafts made from quenched and tempered steel to rolling bearing quality.
The material quality guarantees high dimensional and geometrical accuracy (roundness, parallelism). Due to their high surface hardness and surface quality, the shafts are highly suitable as precision raceways for linear ball bearings.
High precision shafts are also suitable as guide rods for plain bushes, as stretch and levelling rollers and in the construction of equipment and automatic machinery.
They can be combined with linear bearings, yoke and stud type track rollers, ball bearing track rollers and profiled track rollers to give linear guidance systems that are rigid, precise, economical and ready to fit, with high load carrying capacity and a long operating life.
Shafts are made from steel Cf53 induction hardened and ground; the surface hardness is 670 HV + 170 HV (59 HRC + 6 HRC)
