Four-Row Tapered Roller Bearings

If you're in the market for new roller bearings, you may want to consider buying four-row tapered roller bearings. These bearings have a number of advantages, including improved internal design and uniform bearing rolling element contact surface pressure. The result is a high load capacity and a high resistance to wear. This type of bearing also features a more compact design and improved sealing performance.

Timken

Timken produces one of the largest lines of tapered roller bearings in the world. They have four interdependent components and are designed to handle radial and thrust loads. They are used in a variety of industries, including heavy trucks and aerospace.

NTN

NTN four-row tapered roller bearing designs differ from conventionally designed bearings in two important ways: cage design and roller design. In a cage, there are two rings, one of which has a series of pins along its circumference, which thread onto the rollers. The other ring is welded to the ends of the pins. The most common cage type is a polymer one, but non-ferrous metal cages can also be used. The more rollers in the bearing, the higher the load capacity. However, a higher number of rollers means that it's less efficient in high-speed applications, vibration, and dynamic load conditions.

Austin Engineering Company Limited

Four-row tapered roller bearings are a common type of rolling bearing with four sets of tapered rollers and raceways. This type of bearing offers high stiffness and a large load capacity. These bearings also have the advantage of carrying axial loads in both directions. They typically consist of three outer rings and two double-row inner rings, which are held together by spacers.

NEWORLD

Four-row tapered roller bearings are highly specialized bearings that are designed to accommodate high axial and combined loads. They are nearly exclusively used in work roll applications. The four-row design of these bearings allows for an optimal load distribution over the entire bearing. These bearings are available in sealed and re-lubrication versions. Some of these bearings are even available for highly contaminated applications.

TQO

Four-row tapered roller bearings are a versatile type of bearing. Their design is based on a four-cup configuration, which provides optimum load distribution across all four rows of rollers. Its design also supports the formation of a hydrodynamic lubricant film. The cylindrically-shaped outer race features two cups or cones, as well as slots and lubrication holes.

ETI

ETI four-row tapered roller bearing is a type of rolling bearing that is characterized by a four-row design. These bearings are usually press-forged steel, and they are used when high stiffness and tilting moments are required. These bearings are also used in vertical cylinders in all-purpose steel mills.
