Description
- High load capacity in all load directions, including moments about all axes, due to the use of largest possible ball sizes.
- Size 15 and up with a lube nipples on the end face and relubrication port on the side
- Low friction
- All steel parts of the runner block are made of corrosion-resistant, martensitic steel.
- The runner blocks are delivered on a mounting aid.
Features
- Accuracy classes P, H and N
- Relubrication hole available
- Smooth, quiet running thanks to optimally designed ball return and guidance
- Ball retention for easy replacement

| 1) | Only with pre-tensioned systems. For non-pre-tensioned systems: amax = 50 m/s2 |
| 2) | Speeds of up to 5 m/s are possible. Service life is limited by increased wear to plastic parts. |
| 3) | Brief peaks up to 100°C are permissible. |
Note on dynamic load capacities and moments (see the table)
Determination of the dynamic load ratings and moments is based on a total travel of 100,000 m.
Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
Observe friction of the different seals. See document “Technical data”.
