Bearing type and feature E-type cylindrical roller bearings Main dimensions and bearing the same general import, but the roller diameter, length, number of increased load bearing capacity to increase correspondingly.With symbol "E" number on the basic NTN bearings in order to differentiate. Compared with the large load capacity, its design is very light. Because the bearing diameter and bearing the standard import different,

1, ntn Bearing Parts Material Imported bearing cage play an equal distance in the rolling bearing isolation to prevent the ball rolling and falling, to guide and promote the role of ball rotation. Can be divided into stamping rolling bearing cage and solid cage. Rolling at work, as a result of sliding friction and wear of bearings fever, especially in the high-speed operation conditions, due to the centrifugal force,

1: ntn bearing cage material:ntn bearing cage material, the use of low carbon steel. According to different uses, also used yellow copper, stainless steel plate. Cut to cage materials, use of high strength brass, carbon steel, in addition also has the use of synthetic resin.Mechanical strength, good dimensional stability, will also need good processing. According to different uses, as well as requirements of its impact resistance, heat resistance, good corrosion resistance.

ntn bearings require lubrication in order to ensure maximum service life, many users do not know how to lubricate bearings, causing premature bearing damage.ntn bearings bearing is not easy to bad lubrication is good, so so that bearing life is too short. Here is the relevant knowledge on the bearing area include the following aspects:1, first of all the various parts of the bearing lubrication, reducing bearing friction and wear;

Incorrect installation and removal will reduce bearing life. When a small bearing assembly will enable the hand-hammer and a simple auxiliary sleeve. For medium and small bearings, installation of hydraulic machine can be used to exert pressure on the inner ring will be set to a journal on the bearing pressure for larger medium and large bearings, often used temperature method assembly

ntn bearings in high speed rotation, in particular the speed close to or exceeding the limits of record size of the table speed, the main should pay attention to the following(1) The use of precision bearings;(2) Analysis of the internal bearing clearance (taking into account the bearing temperature rise resulting reduction in the amount of internal clearance);(3) analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system.
