nachi

NACHI can produce products can cover almost all of the machinery industry, including robotic systems, machine tools, tools, vehicles, large equipment and so on.
Rolling size classification
It can bear the load direction classification
① radial bearings, also known as radial bearings, radial load.
② thrust bearing, also known as thrust bearings, axial load.
③ radial thrust bearing, also known as radial thrust bearing, both radial and axial load. Friction bearing according to the nature of the work can be divided into sliding friction bearings (referred to as the sliding bearings) and rolling friction bearings (referred Rolling) two categories.
The Nachi bearings business started out by using the superior materials made by our own company, and by applying expertise in cutting and heat treatment acquired from our experience with cutting-tool manufacturing. As a result, you get high speed and high precision bearings that are durable and compact. Benefi? tting from our continually advancing technology, these parts are at work in automobiles, industrial machinery, and equipment in various other sectors. Everywhere you look, our Nachi bearings contribute to better reliability.

Structure and performance characteristics NACHI bearings
Axial angular contact ball bearings
Axial angular contact ball bearing contact angle is generally 60 ° common thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindle, general and double row cylindrical roller bearings are used together with, affordable two-way shaft to load, with high accuracy, good rigidity, low temperature, high speed, easy assembly and disassembly, etc..
Deep groove ball bearings
In the structure of each ring of deep groove ball bearings have a cross-section of approximately the equatorial circumference of the ball one-third of the continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also bear certain axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearing can withstand both directions alternating axial load. Compared with the same size compared to other types of bearings, such bearings friction coefficient is small, extreme high speed, high precision, user selection of the preferred bearing type. Deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used of a class of bearings.
Thrust tapered roller bearings
Since the thrust tapered roller bearings in rolling element tapered roller, rolling bus washer raceway on the bus structure are remitted to the bearing axis line of a point, and thus the rolling surface may be formed of pure rolling, high speed limit thrust cylindrical roller bearings.
Features:
1. Thrust tapered roller bearings can withstand axial load unidirectional. Thrust tapered roller bearing type code is 90000.
4, bearings of double row tapered roller structure, the performance characteristics of the bearings
Double row tapered roller bearing structure range is the maximum amount of 35,000 type, there is a double outer ring raceway and two inner ring, a spacer between two inner ring, a change in thickness of the spacer adjustable clearance.
Such bearing radial load at the same time can withstand two-way axial load, and can limit the axial displacement in the housing bearing axial clearance range. Tapered roller bearing structural features of.
Tapered roller bearing type code 30000, tapered roller bearings for the separation of bearings.
Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can withstand axial load in one direction, a direction to limit axial displacement of shaft or housing.
