Four row tapered roller bearing

The optimized four column roller load distribution can provide higher radial and axial bearing capacity, with long service life, high operational reliability, and detachable installation method, providing more convenient disassembly and maintenance services. It can provide metric and imperial size series products.

Characteristics and advantages

Depending on its design, four row tapered roller bearings provide the following main features and advantages:

Long service life

The four cup design provides optimal load distribution on all four rows of rollers.

Improve operational reliability

Optimizing the surface treatment of the contact surface between the roller and the raceway is beneficial for the formation of a hydrodynamic lubricating oil film.

The load-bearing capacity of sealed bearings and open bearings is the same

Optimized and compact sealing design can achieve the same internal design.

Complete interchangeability of bearings

Both with and without spacer bearings, as well as open and sealed bearings, are available in the same external size model.

Separable installation and simpler inspection

The optimized design without spacer allows for the disassembly and separation of roller and cage components and seals, which facilitates installation, disassembly, and maintenance inspection procedures.
