Provisions for mounting and dismounting
Particularly when large bearings are involved, SKF recommends that during the design stage you make provisions to facilitate mounting and dismounting, including:
- slots or recesses machined in the shaft or housing shoulders so that withdrawal tools can be used (fig. 1)
- threaded holes in the housing shoulders so that bolts can be used for dismounting (fig. 2)
oil supply ducts and distribution grooves in the shaft to enable the oil injection method to be used (fig. 3)
Recommended dimensions for oil supply ducts and distribution grooves are listed in table 1, and for threaded holes in table 2. When using the oil injection method, Ra should not exceed 1,6 μm.
