ZKL expands its range of thrust spherical roller bearings with another giant bearing

At the end of the month, the ZKL Brno production plant leaves four of the largest thrust spherical roller bearings with the designation 294/1000EM NF. This new dimension of axial spherical roller bearing with a massive brass cage is designed for the air pre-heaters in the heat power plants.

The bearing reaches respectable dimensions. 1670 mm is the size of the outer and 1000 mm of the inner diameter. The total bearing weight is 3390 kg, with a single rolling element weighing 43 kg. These parameters place high demands not only on production, assembly, but also on logistics. The final destination is China, where this cargo travels in a specially modified container by rail.


ZKL is the biggest manufacturer of large-scale spherical-roller, special and split bearings in Central Europe.
