SNL528 K7 SKF Housing with bearing seating diameter tolerance K7

SNL plummer block housings have several advantages, such as the high load carrying capacity and machining quality as well as the wide variety of sealing alternatives with the following design and performance characteristics. The housing base is reinforced with ribs and extra material surrounding the holes for the attachment bolts in order to provide improved seating on the base plate. The attachment bolts can be preloaded to give correct location and prevent deformation of the housing base and bore. The reinforcement of the housing base enlarges the contact area between base and base plate and allows for an improved heat flow from the bearing outer ring to the base plate. The bearings will run 5 to 10 % cooler than in other housings. Another benefit is the choice of oil or grease lubrication for the bearings housed in SNL plummer blocks. A range of efficient seals for oil lubrication and rough environments make for trouble-free operation.
