Needle Roller Bearing NK16/16 photoes showing
A needle roller bearing is a bearing which uses small cylindrical rollers.The difference between a needle roller bearing and
roller bearing is the ratio of diameter and length of their rollers, when the ratio of the diameter and the length of roller of a
roller bearing is between the interval of 0.1 to 0.4, that roller bearing is called a needle roller bearing.They are used to reduce the friction of a rotating surface.
Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings.
Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact. The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race (sometimes the housing itself).
Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.
Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the
largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for
particularly compact designs.
Needle Roller bearing Components
ENKI needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life. In spite of their low cross section, needle roller bearings have a high load carrying capacity. Therefore, they are extremely suitable for bearing arrangements where radial space is limited.
ENKI supplies needle roller bearings in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications.
ENKI supplies needle roller thrust bearings in two designs:
needle roller and cage thrust assemblies, AXK series
needle roller thrust bearings with a centring flange, AXW series
In applications where adjacent components cannot serve as raceways, the assemblies can be combined with bearing washers in different series (→ Bearing washers).

Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from ENKI in many designs, variants and sizes.

Our Team
The customer from Pakistan was looking for a special bearing, whose loading capacity is very large, because the bearing will be used in rails. After discussing, we designed the bearing according to his requirements and supplied the samples to him for testing. Then we started our business until now.
Jack Liu and General manager Mr. Song are discussing the ceramic bearing and ceramic layer insulation bearing with the customer from Thailand. The bearings in this order are used in Motor and Generator, the insulativity and speed are very important. Now our ceramic bearings are working very well from our customer's feedback.
The beautiful women is from Ukraine and she is looking for the micro deep groove ball bearings. After visiting our factory, they choose us as longterm business partner in China.
A: We are factory manufacturing ball bearings for many years in China.
