Description

Materiale
Forma A:
acciaio per utensili, durezza del materiale 58-62 HRC.
Le superfici sono finemente rettificate.
Forma B:
acciaio automatico con guarnizioni di scorrimento in PTFE.
Le guarnizioni di scorrimento sono autolubrificanti.
Indicazioni per l'effettuazione dell'ordine d'acquisto
Per una guida completa con guida di dimensione 6, una lunghezza di guida di 300 mm e una corsa di 100 mm sono richiesti:

2 x 21054-1060300
2 x 21054-2060200

(indicare la lunghezza L, ad es. 030 per L = 30 mm)
Nota
When lubricated and under normal conditions, speeds of up to 15 m/min. can be achieved.
Depending on the lubricant, the coefficient of friction can be calculated as 0.04–0.08.
Standard slideway lubricants are applied.
The longitudinal guides are used for moving, machining and positioning tasks.
Application
- Industry automation
- Machine tools
- Special machinery
- Tool fixtures
- Metrology equipment
Temperature range
-40 °C to +80 °C.
Advantages
- Stick-slip free movement
- Very good dry-running properties
- Highly wear-resistant
- Very good vibration damping
- Resistant to dirt, shock and impact
