Guide rods
Guide rod HW
These rods are surface-hardened and ground. They are mainly used as linear guidance of ball and sliding bearings where sufficient lubracation and corrosion protection is ensured. Surface of these rods is not resistant to corrosion. If complete corrosion protection cannot be guaranteed, you should use chromed or stainless steel guide rods. All guide rods are surface-hardened. This treatment increases hardness of the surface of the rod, but also makes it more brittle. As a result, its abrasion resistance increases and the core of the rod remains tough. These guide rods can be delivered also in inch measurements, they are then marked as HWZ.
Parameters:
Used materials: CK55, eventually C60
Manufactured diameters range: 4 -120 mm
Manufactured diameters range in inches: 1/4" -3"
Diameter tolerance h6
Surface roughness Ra max 0,2 μm
Induction hardened layer hardness 62±2 HRC
Production lengths 6 m, tolerance 0 - +200 mm
(due to manufacturing technology, surface tolerance
or depth of the hardening cannot be guaranteed
100 mm from each end of the rod)
Chromed guide rod HWV
HWV guide rods have chromed surface when compared to the HW type. This layer provides very good resistance to wear and corrosion, it has long lifespan and reduces friction. If the guide rod should be permanently exposed to aggresive weather conditions, it is advisable to use stainless steel one instead. These guide rods can be delivered also in inch measurements, they are then marked as HWVZ.

100 mm from each end of the rod)
Stainless steel guide rod HWVRA
Stainless steel guide rods made of X90CrMoV18 material with addition of molybdenum and vanadium are the best for extreme conditions. They are used, just like the previous ones, mainly as linear guidance of ball and sliding bearings. The X90CrMoV18 material guarantees maximal corrosion resistance. These rods are also surface-hardened. They can be delivered also in inch measurements, they are then marked as HWVRAZ.
Parameters:
Used materials: X90CrMoV18 W-Nr.1.4112
Manufactured diameters range: 5 - 60 mm
Manufactured diameters range in inches: 1/4" - 2 1/4"
Diameter tolerance h6
Surface roughness Ra max 0,2 μm
Induction hardened layer hardness 56±3 HRC
Production lengths 6 m, tolerance 0 - +200 mm
(due to manufacturing technology, surface tolerance
or depth of the hardening cannot be guaranteed
100 mm from each end of the rod)
Stainless steel guide rod HWVRB
These rods are made of X46Cr13 material. They are cheaper than HWVRA rods, have got lower tensile strength and their hardened layer has lower hardness. However, they still have excellent properties when used as linear guidance of ball and sliding bearings. The X46Cr13 material guarantees very good corrosion resistance. They can be delivered also in inch measurements, they are then marked as HWVRBZ.
Parameters:
Used materials: X46Cr13
Manufactured diameters range: 5 - 60 mm
Manufactured diameters range in inches: 1/4" - 2 1/4"
Diameter tolerance h6
Surface roughness Ra max 0,2 μm
Induction hardened layer hardness 55±3 HRC
Production lengths 6 m, tolerance 0 - +200 mm
(due to manufacturing technology, surface tolerance
or depth of the hardening cannot be guaranteed
100 mm from each end of the rod)
Hollow guide rod HWH
Hollow guide rods are made of C55 or C60 material. They are mostly used in long lines with need for lesser weight. Surface of these rods is not resistant to corrosion, it is advisable to treat them regularly with lubricant or other anti corrosion agent. They can be delivered also in inch measurements, they are then marked as HWHZ.

(due to manufacturing technology, surface tolerance
or depth of the hardening cannot be guaranteed
100 mm from each end of the rod)
Chromed hollow guide rod HWHV
Chromed hollow guide rods are too made of C55 or C60 material. In addition they have chromed surface providing very good resistance against wear and corrosion, it has long lifespan and reduces friction. They can be delivered also in inch measurements, they are then marked as HWHVZ.
