• Special rollers in stainless (NIRO) design with suffix . . . VA, e.g. NFR 22 VA.
• Track rollers are provided with a labyrinth seal on both sides.
• Please enquire about heat-stabilised rollers.
• Sb = lubrication facility on the thread side only from NFR/E 40.
• * = during the transition phase, NFR/E 110 may still be supplied with a slot.

• Machine housing bores Ø I H7.
• max. angular error of the rolling plane to the bore axis ± 5′.
• fastening material shown is included in the scope of supply.
• Load ratings and limit loads only valid with full contact of the roller disc against a housing face.
• Tightening torques for unlubricated threads. For lubricated threads multiply by 0.7.
• *For new designs use FR80-22-AN.

• Machine housing bores Ø I H7.
• max. angular error of the rolling plane to the bore axis ± 5′.
• Spirallock locking thread; lock washers are supplied.
• Load ratings and limit loads only valid with full contact of the roller disc against a housing face.

Series KFRS/KFRSE are supplied without cylinder head screws.

Please speak to our application engineers before using these series.

These series are shown for completeness only. As a functional part they do not represent an economically sensible unit and should only be used where existing designs require them.

Our precision guide rails are manufactured in induction-hardened design. The base material is a high-chromium tool steel which, with a hardness of 60 ±2 HRC, guarantees long service life and maximum load capacity of these high-performance guide elements. Please also state your desired rail length with your enquiry. Lengths of ?=1500 mm are often achievable. The precision guide rails can be joined to form unlimited lengths. Please indicate this when ordering. The sections are marked by us and can be assembled without error.

• Hardened zone: raceways induction-hardened
• All edges: R = 0.5±0.2 mm
• Twist: max. 2°/m
• Straightness deviation: max. 0.5 mm/m
• Length: max. 1.5 m/pc.

• Hardened zone: raceways induction-hardened
• All edges: R = 0.5±0.2 mm
• Twist: max. 2°/m
• Straightness deviation: max. 0.5 mm/m
• Length: max. 6 m/pc.

All precision guide rails are fundamentally marked with our company logo and the manufacturing number. On request you can receive a measurement report. For special designs that deviate from our standard in dimensions or in the type of heat or surface treatment, please enquire. Sizes PFSH 22-72 are also available as “bright-drawn”. Please refer to table PFSH...GIK. Precision guide rails made of corrosion-resistant steel are available with the suffix “VA”. Please enquire about delivery times.

Our precision round guides are manufactured up to a diameter of 700 mm. Material selection and hardening process according to the desired properties.

In special cases it is possible to manufacture larger diameters, or to execute material grades and surface treatments to your requirements. For a necessary cost-effectiveness assessment, please contact our Technical Service.

All precision round guides can also be assembled from circular segments. It is likewise possible to manufacture individual segments for cam mechanisms.

The precision round guides are fundamentally marked with our company logo and the manufacturing number. On request you can receive a measurement report.

All guide strips are manufactured to your required dimensions. Please discuss the application with us; we will be happy to advise you regarding surface finish, hardness and cost-effective rail dimensions.

In combination with guide rails series PFS / PFSH, the guide strips enable the manufacture of guides according to the fixed-bearing / floating-bearing principle.

We manufacture the guide strips to match the guide rails you use. This means the same pitch dimensions of the rollers used.

On request the guide strips can be manufactured from corrosion-resistant steel. Special surface treatments are also possible.

Material: 100 Cr6

Ordering example: shaft with 25 mm outside diameter and 2000 mm length: WH 25 h7 x 2000.

We machine induction-hardened shafts to your specifications.
