Single row tapered roller bearings, inch sizes, are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved. • High radial and axial load carrying capacity • Accommodate axial loads in one direction • Low friction and long service life • Separable and interchangeable components

• High radial and axial load carrying capacity
• Accommodate axial loads in one direction
• Low friction and long service life
• Separable and interchangeable components

Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.

Bearing Features:

Depending on their design, four-row tapered roller bearings provide the following main features and benefits:

• Long service life: The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.
• Enhanced operational reliability: Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Improved wear resistance: In particular, SKF Explorer bearings are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.
• Improved sealing performance with less leakage and less frictional heat: The optimized seal design ensures high protection against external contamination but keeps friction and frictional heat low. This seal design also provides a better retention of lubricant, minimizes environmental impact and reduces maintenance costs.
• Equal load carrying capacity for sealed and open bearings: The optimized and compact seal design enables identical internal design.
• Total bearing interchangeability: Bearings with and without intermediate rings as well as open and sealed bearings are available with identical external dimensions. This allows total bearing interchangeability of current standard design bearings with those without intermediate rings and/or with optimized seal design.
• Separable mounting and simpler inspection: Optimized designs without intermediate rings enable to dismount and separate the cage and roller assemblies and seals. This facilitates mounting, dismounting and also maintenance inspection routines.
• Axial space-saving and cost-effective solution for roll necks: The roll necks can be relatively short, no separate axial bearings are required and identically designed chocks can be used on both sides of the roll.
• Simple axial location on roll necks: Tighter inner ring width tolerances facilitate the tolerancing and dimensioning of surrounding components.

Taper Roller bearings are generally separable, which means the cone assembly, consisting of the inner ring with roller and cage, can be mounted separately from the cup (outer ring). Being separable, mounting becomes easier. The projection lines of all the taper surfaces (Cup, Cone, and Roller) meet at a common point on the bearing axis, called the apex point, ensuring proper rolling motion of the roller on the track surfaces of cone and cup. NBC manufactures Single and Double Row Taper roller bearings in Inch and Metric series. These bearings are mainly used in Wheels, Transmissions and Axle Centres of Passenger Cars, MUVs, Trucks, Tractors, Earthmovers, etc. where RPM is moderate and combination loads (i.e. simultaneously both axial and radial loads) are prevalent.
