Needle Thrust Bearing- Best Suited to Handle High Axial Load

Every mechanical function needs smooth rotation, an even distribution of weight, less damage to bearing and less oscillation as well movement during the rotation. To fulfil all these needs a thrust bearing is used. This bearing fall under type of rotary bearing. This is similar to other bearing as it allows rotation in between parts, however designed to provide support high axial type load when in rotation. Here we will cover about needle thrust bearing

Usage and Specifications

Thrust bearing is available in different range and variety and is supported within a ring. Thus it allows usage even in low thrust applications where there is presence of minimum axial load. In automobile machineries like rocker arm pivots, compressor, pumps, transmissions etc. needle thrust bearings is commonly used.

In those condition, wherein high axial type of load capacity is required with minimal envelope space, needle thrust bearing is used. This type of bearing contains machined or stamped type of rollers and cage. Also cage holding rollers are paired with the thrust washer and it performs as raceways. The needle thrust bearings gives high degree stiffness and thus are best suited where high accuracy is essential at high speed like in machine tool and pumps with high pressure. Where space is major issues or requires large radial load, Needle rollers are commonly used

Needle Bearing Catalogue

Catalogueis replica of the product in printed form. It contains complete list of items, typically one in alphabetical or in specification wise order. Accordingly, in general term for a bearing catalogue for needle thrust make will have detailed information to serve multi purposes like product detail, detailed specification, ideal bearing model with application, measurement, specifics etc. A complete and detailed look at the needle bearing catalogue can provide the following information at a glance:

• Main features
• About the Form, Number of rows of the rolling elements
• Bearing Loads
• Bearing Selection
• Bearing Tables
• How does it offer Flexibility in case of misalignment
• Bearing mounting in details

Further section in the catalogue provides in detail about placing of the bearing in right way or how will it accommodate in case of both radial / axial load is applied together or separately. A catalogue will have detailed specification about the needle thrust bearing and other types of and anyone can get entire detail of the product readily available.

Another type i.e. Tapered roller type of bearing are generally used in application rolling mills, gear reducer, shafting gears, transmissions, machine tool spindle. It is required with low speed application, suffice grease lubrication but then again high speedsrequire an oil lubrication. Also in case of extreme high speeds special lubricating arrangement are required.
