RECIRCULATING BALL BEARING BLOCKS

Calculation of lubricant consumption during recirculating ball bearing block lubrication

When a bearing block under load is moved, friction is generated as a result of the action of the balls located between the bearing block itself and the guide rail. Correct lubrication is essential to protect the surfaces of the parts in contact and to reduce friction and overheating.

REMARKS AND ADDITIONAL NOTES
The lubricant values calculated with the previous formulas have the indicated value and in any case are valid for:
- Automatic Plant
- Continuous service
- Normal operating conditions

Please note that this volume may be affected by heavy-duty operating conditions and in any case by the following factors:
- Impact and/or Heating
- Speed of the part to be lubricated (number of revolutions or number of strokes per hour)
- Specific pressure between contact surfaces
- Presence of dirt, water ingress, contaminants

It is possible to apply corrections to the lubricant supply (service factor) in the presence of special conditions, due to environmental situations or specific to the part to be lubricated. Specifically:
- 0,5 for intermittent service
- 1.0 for continuous service (considered in this specification)
- 2.0 for medium-heavy continuous service
- 4,0 for heavy-duty continuous service
