Sliding bearing housing
Housing bearings are used as holders for sliding bearings together with shafts. Where the bearing seat/sheet metal wall cannot support the sliding bearing, our housing bearings can be used. They are very easy to install and are delivered complete with sliding bearings. As standard, the housing bearings are delivered with lubrication free sliding bearing of type BK1. At dirty environments and where lubrication is desired, we also have housing bearings with low-lubrication sliding bearing of type BK2 with grease pockets.
Our hard-chromed shafts with tolerance f7 work well with these housing bearings.
| Max load is calculated on the basis of the projected bearing surface. |
