Features
- Features of Spherical Roller Bearings.
- The inner ring assembly of a tapered roller is referred to as the cone, while the outer ring is called the cup.
- Tapered rollers are guided by the cone back face rib.
- This bearing design is suitable for heavy radial loading and a sizeable amount of axial loading.
- The taper of the rollers and the cone raceways have a common apex on the bearing axis.
- The angle between the cup raceway and the bearing axis is the contact angle.
- The larger the contact angle the greater the bearings axial load capacity.
- The cone and cup are separable simplifying bearing mounting.
- Single row bearings can accommodate radial load and axial load in one direction.
- Two single row bearings are used opposing each other to simplify setting of the proper clearance between the two rows.
- The two row design can handle radial load and an axial load in either direction.
- The two row design is available as a TDO (double outer race), or a TDI (double inner race).
- Two row taper designs are normally supplied with spacers to provide a pre-adjusted assembly.
- The four row design is commonly used on rolling mill roll necks for their large load carrying capacity.
- Cages used can be a pressed steel or a pin type.
- Cage types can be pressed steel, machined copper alloy.
