The SKF SSNHD line covers solid-base split plummer block housings that hold and locate bearings in rotating machinery. Because the housing comes in two halves, the shaft does not have to be pulled out for inspection or replacement, which shortens downtime. Typical duty includes conveyors, mills, pumps and industrial fans, where the bearing needs firm clamping and correct alignment.
Reading the code helps narrow down the right unit. The letters SSNHD mark a solid-base split plummer block housing, and the figures after them give the size and, where shown, the bearing combination. So SSNHD 510-608 pairs a 608 series bearing with a 510 mm shaft, while SSNHD 517 is a size on its own with no bearing suffix. Other combinations in the range include SSNHD 515-612, SSNHD 519-616, SSNHD 522-619, SSNHD 524-620 and SSNHD 528. Always confirm the full code against the bearing that will be fitted.
These housings turn up in food processing, cement, mining and bulk material handling. Belt conveyors, bucket elevators, mixers, mills and centrifugal pumps are common homes for them. The solid base takes combined loads and vibration, so they suit equipment working under heavy stress. Maintenance crews specify them on lines where uptime and simple service access matter most.
Selection comes down to shaft diameter, bearing type and size, and the radial and axial loads the application will see. Fitting calls for a flat, rigid mounting surface, careful alignment and even tightening of the connecting bolts. Follow the bearing maker's lubrication instructions, and rely on the housing seal to keep out dust and moisture. Before start-up, check internal clearance and concentricity.
Other makers build split plummer block housings to similar dimensions, but that does not make them drop-in replacements. Tolerances, materials and sealing arrangements differ, and those differences can change how the assembly performs. Compare the technical data and speak with a specialist before substituting one housing for another. We can review compatibility with other brands and series.

Frequently asked questions
- What does the SSNHD designation mean in SKF housings?
- SSNHD identifies a series of solid-base split plummer block housings. The number that follows gives the size and, in some cases, the bearing combination. SSNHD 510-608, for instance, is a housing for a 608 bearing with a 510 mm shaft.
- How do I choose the right SSNHD housing for my application?
- Start with the shaft diameter, the bearing type and size, and the radial and axial loads. The working environment and sealing method also matter. With those details we can point you to the exact model in the SSNHD series.
- Are SSNHD housings interchangeable with those of other brands?
- Not always. Dimensions may line up, but tolerances, materials and seals vary from one manufacturer to another. Check the technical specifications and consult us before swapping in a housing from a different brand.
