Tapered roller bearings are separable bearings. The inner and outer rings are separated.
In tapered roller bearings, the outer ring is sometimes referred to as the “cup” and the inner ring assembly as the cone. These are sometimes called “sub-units”, with a single bearing referred to as the “unit”.
Your Leading Tapered Roller Bearing Assembly Supplier
SUN AUTOMATION GROUP LIMITED was founded in 1986 and had been focusing on exporting high bearing ever since. Our tapered roller bearing includes four-row tapered roller bearing, tapered roller bearing assembly, double-row tapered roller bearing and single-row tapered roller bearing. Tapered roller bearings are used in applications requiring the support of heavy loads and a combination of radial and axial forces, such as in vehicle wheel ends, heavy machinery like those for construction and mining, and industrial gearboxes. We have a stock warehouse and provide a variety of stock bearings.

Features of Tapered Roller Bearing Assembly
• This variant of roller bearings can be customized to match specific speed, weight, temperature, etc.
• The cup is made of the outer ring of the bearing and cone assembly includes inner ring, rollers and cage.
• The design effectively helps combine two bearings for a higher impact on productivity.
• The separable components ensure a safe mounting and unmounting.
• Works well in high speed and high temperature applications.

Heat Treatment of Tapered Roller Bearing Assembly
There are three typical hardening methods that may be applied to bearing components:
Through-hardening
This is the standard method for most bearings and provides good fatigue and wear-resistance, as hardening is applied over the full cross section.
Induction-hardening
Surface induction-hardening is used to selectively harden a component's raceway to limit rolling contact fatigue, leaving the remainder of the component unaffected to maintain structural strength.
Case-hardening
Case-hardening provides hardness to the surface. It is used, for example, where bearing rings are subjected to high impact loads causing structural deformations.
Precautions for Using Tapered Roller Bearing Assembly
Non-combination forces: Ball bearings and other simpler alternatives have less friction overall and are likely sufficient for non-specialty purposes that lack combination forces or a need for high surface-area contact.
Combination forces: A combination of axial and radial loads almost always requires a tapered roller bearing.
Determining load capacity: The contact angle determines the load capacity, so it's essential to decide the load angles a bearing will handle. For heavy-duty applications, multi-row tapered bearings are necessary for combination loads. With lighter forces, one is often enough.
Determining contact angles: The contact angle between a component and the bearing will determine the outer ring raceway angle. More significant contact angles translate to higher axial load capacities and vice versa. When selecting the correct tapered bearing for your needs, you'll see this angle often expressed with the coefficient 'e'; higher values indicate both greater contact angles and axial load-bearing capacity.
Storage Requirements for Tapered Roller Bearing Assembly
Leave bearings in the package until ready for assembly. Do not wash off the lubricant covering them.
Bearing lubrication protects the surface from corrosion, sealing against contaminants.
Clean, dry, and vibration-free storage conditions are best.
