Double Row Taper Roller Bearing | 5.imimg.com
When it comes to meet particular speed, temperature, vibration, load and contamination conditions, a tapered roller bearing is used. The bearing is tailor-made to suit any applications that demand operating under the above-mentioned conditions. With a cone assembly and cup, where the cup consists of an outer ring and the cone assembly having rollers, a cage and an inner ring, the tapered bearing handles a combination of axial and radial loads, with low friction.
You can have a high rigidity by having an additional row of bearing with a single row tapered roller bearing. With variations in designs, this bearing can serve a number of purposes. A few designs to mention are: Single-row taper roller bearings, double-row taper roller bearings and four-row taper roller bearings. Among these, a double row taper roller bearing is largely used in automobile industry, rolling mills and machine tools.
Merits of a Double-Row Tapered Bearings
The distinctive feature of a double row taper roller bearing is its second row of rolling elements, which make it appropriate for applications asking for managing heavy axial and radial loads. The following are the other features and a few benefits of this bearing.
Handle Heavy Loads: With this two-row taper roller bearing design variant, you can support both radial and axial loads. The capacity to handle axial load increases with the increase of the contact angle, which has its size generally between 10 degrees and 30 degrees. The calculation factor, to which the size of the contact angle is related to, decide the angle size. Where the value is larger, the size is also larger.
Low Friction: The design of a double row taper roller bearing helps form a lubricant film to minimize friction. The flange has a surface finish that leads to reduced wear and frictional heat. With better preload maintenance, it operates at reduced noise levels.
High Rigidity: The bearing is known for its stiff arrangement.
Various Uses of Double Row Taper Roller Bearings
You can find their use in sophisticated applications like gear boxes, rolling mills, machine tools, printing equipment, and more. In many cases they are employed in back-to-back pairs to accommodate axial loads simultaneously in either direction. With the roller profiles designed to give close geographical tolerances and dimensions, they look quite identical and offer optimal load transmission and accurate preload setting.
