These products have been used to carry loads from tens of kilos up to hundreds of tonnes. To use a combined roller bearing, a hole the same size as the spigot on the rear of the hub is drilled or milled in a steel member. The hub is then welded into place, filling the 45º weld fillet around the circumference of the spigot with weld. An optional mounting plate is available that allows the user to pre-weld the bearing to the plate and then attach the plate using bolt and nut through clearance holes or machine screws into the threaded holes in the plate. In use, the combined roller bearing engages in a C- or H-section profiled steel section. The radial roller engages on the flanges of the profiled section and the axial roller engages on the web of the profiled section. These sections are much thicker and heavier in section than standard beams or columns. The profile is formed to exactly match the bearings outer profile.
