Product description of KOYO Bearing NTA-2840

KOYO Thrust needle roller bearings Inch series, separate type, KOYO Bearing NTA-2840,NEEDLE ROLLER THRUST BEARINGS, assailable in5 mm to 160 mm PhD to 6 V/4 in) bore, consist of a complement of needle rollers held in place by cage. Needle roller thrust bearings are complements of small diameter needle rollers arranged in a spoke-like configuration. KOYO Thrust needle roller bearings Inch series, separate type, KOYO Bearing NTA-2840, Needle Rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greasy reducing friction.Needle roller thrust bearings also can be united with lapped washers which service as raceway surfaces for the needle rollers.

Washers can be supplied separately or can be mechanically untied to the needle roller thrust assemblies for ease of handing.

KOYO Thrust needle roller bearings Inch series, separate type, KOYO Bearing NTA-2840, In terms of environmental friendliness, there has been a rapidly increasing demand for smaller, lighter products, as well as lower friction, higher reliability, and higher functionality in many different industrial fields.Our needle roller bearings are the optimal solution to all such requirements.

In 2010, as part of JTEKT's continual process for improvement in the needle roller bearing business, we integrated the technology of Torrington, a company with a long history in the United States and Europe, into the Koyo brand of traditional needle roller bearings. In 2013, the Koyo brand will take the next step in this line of business to pursue stronger distribution and production structures and further technological development with the aim to accommodate our customers' needs on a global scale.

On this occasion, JTEKT has fully renewed its needle roller bearing catalog, which we present here. We believe that this new catalog will prove useful in your selection and use of our needle roller bearings. We look forward to your continued patronage.
