Maintenance for linear guideway
Lubrication
The objective of lubrication includes the reduction of friction among the rolling elements as well as between the rolling elements and the raceway, prevention of sintering, reduction of wear, and the prevention of rust by forming a film over the surfaces. To maximize the performance of a linear system, the lubricant type and a lubrication method appropriate for the operating environment should be selected.
Factory pre-lubrication
BR blocks are factory prelubricated with Grease No. 2 and the lubricant reservoir is factory pre-lubricated with Grease No. O. The technical data of grease can be found in table 1.11.2. A preservative is applied to the BR rails and blocks to protect them during transport, storage and mounting. When using the recommended lubricants, it is not necessary to remove this preservative.
Initial lubrication
Initial lubrication is not required, as BR linear guideway is delivered pre-lubricated and ready to install unless specified otherwise. In cases where a different type of grease is required, the blocks should be thoroughly cleaned and regreased prior to mounting. Please refer to table 1.11.1 for appropriate grease quantity.
This initial lubircation has to be applied according to the steps below:
- 1.
Grease each block according to the quantities listed in table 1.11.1.
- 2.
Move the block three times backwards and forwards with stroke = block length.
- 3.
Repeat steps 1 and 2 again, twice.
- 4.
Check if a lubricating film is visible on the rail.
Grease re-lubrication
Re-lubrication intervals recommendation
• Nominal size 30 and below: per 100km; nominal size 35 and above: per 40km
• Make supplimentary periodically per 3 months.
Oil re-lubrication
• First time re-lubrication: apply to whole internal block, please refer to table 1.11.1 for appropriate grease amount.
• Re-lubrication amount: Q=n/150 (cm3/hrs) n: Nominal size of rail (mm)
• Recommended lubricaiton oil spec. ISO VG32-68; ISO VG68-220
