Information on guide rollers & profiles

All-round service package with guaranteed success

The technical basis for every clever solution is our heavy-duty guide system with guide rollers and guide profiles in various designs. Guide rollers and guide profiles from ALFATEC can absorb high radial and axial loads. ALFATEC components are characterized by an outstanding service life.

Our portfolio of combined rollers and guide profiles has been consistently developed further. Every year, 47,500 ALFATEC guide rollers leave our production facility in Filderstadt.

Stable, robust and low-maintenance – these are our combination castors. The ALFATEC combination castors are available in different versions: standard tiger castors, precision castors for precise applications, higher load capacities with the |X|tra-Strong castors, stainless steel castors, ALFA-Speed castors for fast, low-noise handling and mammoth castors for moving the heaviest loads.

Everything is possible in our modular system – always suitable with the corresponding accessories. Our modular system, consisting of combined rollers, guide profiles and other components such as fastening elements, enables you to design and produce simple and cost-effective solutions. ALFATEC components have the advantage of short delivery times, as almost every item is available from stock.

We are happy to manufacture our components to your specifications and drawings.

Technical description of guide rollers

Outer ring

Material steel 20CrMnTi, case-hardened Surface hardness 62-2 HRC


TORX threadlocker DIN 267-28
Polyamide spot coating – no gluing required


Our Tiger rollers are greased with grade 3 lithium grease as standard.


Our Tiger rollers from size 060 can be relubricated to extend their service life. The relubrication holes are sealed with M6 threaded plugs.

Delivered without grease nipple. The rollers must be lubricated at the lubrication connections using a grease gun.

Inner ring

Material bearing steel UNI 100Cr6
Hardness 62-2 HRC


ZRS seal
Labyrinth/elastomer seal, lubricated for life


Cylindrical roller bearings manufactured to DIN 620
Tolerance class: PN (PO)
Load rating factors according to ISO 76 and ISO 281/1
Bolt diameter: 0 / 0.05 mm

Relubrication recommendation

In standard environments such as industrial buildings or warehouses
regular lubrication at intervals of 6-12 months is sufficient.
External factors such as dirt, moisture, temperature, increased operating times or chemical substances can lead to the interval having to be shortened

Weld-on studs

Material S355 J2G3
good weldability

Operating temperature

general: from – 40°C to +120°C; can be used up to +150°C for short periods
High-temperature bearings: up to +250°C


The running surfaces of our combination castors are manufactured with a crowned design. Rollers with a diameter greater than 100 mm must be dismantled before welding.

|X|tra durable: no measurable wear
all profiles are supplied in fixed lengths
Maximum profile length: 8.8 m
Welding recommendation:
On the basis of test results, it is recommended that for a crack-resistant and economical
Welding of fillet welds a two-layer design with a fillet weld thickness of 6 mm
to be used.

Special processing

We are happy to manufacture according to customer drawings or specifications on request.
Simply send us the drawing or tell us the desired pitch.


Before use, the running surfaces of the guide profiles must be cleaned and then coated with grease. A standard commercial grease is sufficient.

The running surfaces should not be painted.
