Remarks
- ●Wipers should be installed in the direction specified in the above schematic.
- ●For the way of installation, check Installation Method.
- ●Refer to the ℓ dimension as it would be differed according to the type of packings to be used together.
- ●As pressure plate flat system requires the inner dimension of pressure bar different from that of SCB-wiper, refer to the table below.
- ●For ℓ(L) dimensions when using the dust seal alone, please refer to the SKY dimensions.
- ※JIS standard sequence of surface roughness symbols refer to HERE.
Dimension table
Dimension table
- 1) For dust-proof application, choose the suitable one out of the standard wipers.
- 2) SDB-wipers have strong wiping ability of oil film on the surface of the rod. Note that the use of them as standard wipers for hydraulic and pneumatic cylinders may wipe out lubricants and grease inside.
- 3) Do not apply any lubricants such as grease to the outer ring surface of wipers and the inside of the housing to avoid floating of wipers from the housing at installation. (no problem in the use for press fit installation)
- 4) At the insertion of the rod, apply grease to the inner ring of wipers and the rod surface to avoid damages on the lip part.
