Types of NACHI Bearings

NACHI  thrust angular contact ball bearings: thrust angular contact ball bearings contact angle is generally 60 ° Commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used in precision machine tool spindle, used with double row cylindrical roller bearings, can bear two-way axial load, with high precision, good rigidity, low-temperature rise, high speed, easy to install and disassemble and other advantages.

NACHI deep groove ball bearings: in the structure of deep groove ball bearings, each ring has a cross-section of about one-third of the equatorial circumference of the ball continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load but also can bear a certain axial load. When the radial clearance of the bearing increases, with the nature of angular contact ball bearing, it can withstand two directions of alternating axial load. Compared with other types of bearings of the same size, this type of bearing friction coefficient is small, has high limit speed and high precision, and is the user selection preferred NACHI bearing type. The deep groove ball bearing structure is simple, easy to use, is the largest production batch, and has the widest range of applications of a class of NACHI bearings.

NACHI thrust tapered roller bearings: As the thrust tapered roller bearings in the rolling body for the tapered roller, in the structure of the rolling bus and gasket raceway bus are intersected in the axis of the bearing at a point that the rolling surface can form a pure rolling, limit speed higher than the thrust cylindrical roller bearings. Features: thrust tapered roller bearings can withstand one-way axial load. The type code of thrust tapered roller bearing is 90000 type. 　

NACHI double row tapered roller bearings: structure of a wide range, the largest number is 35000 type, there is a double raceway outer ring and two inner rings, a spacer between the two inner rings, change the thickness of the spacer can be adjusted clearance. This bearing in radial load simultaneously can bear a two-way axial load. It can be in the NACHI bearing axial clearance range to limit the axial displacement of the shaft and shell. Structural characteristics of tapered roller bearings. Tapered roller bearings type code 30000, tapered roller bearings for the separation type bearings.

NACHI tapered roller bearings: are mainly used to bear the radial and axial combined load. Compared with angular contact ball NACHI bearings, the bearing capacity is large, and the limit speed is low. Tapered roller bearings can withstand the axial load in one direction, limiting the axial displacement of the shaft or shell in one direction.

Features of NACHI Bearings

NACHI can produce products to cover almost all mechanical industries, including robot systems, lathes, tools, automobiles, large equipment, etc. In the mutual contact part of the collar, rolling body and cage that constitute the bearing, metal contact is prevented from reducing friction and wear. The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well-lubricated during rotation. On the contrary, low oil viscosity and poor lubricating film thickness shorten it.

Applications NACHI Bearings

NACHI bearing thrust ball bearings are widely used, NACHI bearing thrust ball bearings are mainly used in transmission devices, engineering machinery, vibrating screens, machine tools, automobiles, metallurgy, mining, petroleum, machinery, electricity, motors, fans, railroads and other industries.
