SRNB (Sealed Four-Row Bearing)
Depending on its design, two tapered bore single cones, one tapered bore double cone, four single cups and three cups with spacer seals can be used in harsher environments.
Offers the following key features and benefits:
Bearings are fully interchangeable
Bearings with and without spacers, as well as open and sealed bearings, are available in the same external dimension designations. This allows full interchangeability of current standard design bearings with bearings without spacers and/or optimized seal designs.
Improve operational reliability
The optimized surface treatment of the contact surfaces of the rollers and raceways facilitates the formation of a hydrodynamic lubricant film.
Detachable installation and easier inspection
The optimized design without spacers allows the removal and separation of the roller and cage assemblies and seals. This facilitates installation, removal and maintenance inspection procedures.
Space-saving cost-effective solution for journals
The journals can be relatively short, no separate axial bearings are required, and bearing housings of the same design can be used on both sides of the roll.
Easier axial positioning on the journal
Tighter inner ring width tolerances facilitate tolerance and sizing of surrounding components.
long lasting
The four-cup design (four independent outer rings) provides optimal load distribution on all four rows of rollers.
