• Industrial: Rolling mill equipment, gear boxes, and machine tool spindles.

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.
