NSK Precision Bearing Series Brief Introduction

NSK Spindle Bearing/NTN bearing/SKF bearing/Imported bearing/Japanese bearing

(New Seiko NTN, NSK bearing agent, NSK bearing distributor)

 

Standard series (high-precision angular contact bearings) (NTN/NSK bearing agent)

●70 series, 79 series

●There are three contact angles: 15°(C), 25°(A5), 30°(A)

●The cage has two types of outer ring guided phenol resin cage (TR) and rolling element guided polyamide resin cage (TYN), which can be selected according to different applications.

 

Low heat generation series (super high-speed angular contact ball bearings) (NTN/NSK super precision bearing agent)

A high-performance series developed to achieve high-speed operation, low temperature rise, and ultra-precision machining applications.

●There are two contact angles: 18°(BNR) and 25°(BER)

●There are two kinds of ball materials: steel ball (S) and ceramic ball (H ▪X)

●There are two types of cages: Outer ring guided phenol resin cage (T), rolling element guided polyamide resin cage (TYN), which can be selected according to different applications.

●The low heat generation series can correspond to ultra-high-speed areas exceeding dm n3 million.

 

(High-speed thrust angular contact ball bearings) (NTN/NSK bearing distributors)

A high-performance series developed for high-speed and high-performance applications such as lathe spindles.

●There are two contact angles: 30°(BAR) and 40°(BTR)

●There are two kinds of ball materials: steel ball (S) and ceramic ball (H)

 

BGR series (ultra-high precision angular contact ball bearings) (NTN/NSK spindle bearing)

It is used for the use of constant pressure pre-tightening methods such as ultra-high-speed internal grinding machine spindles and high-speed motors, and the high-performance series has been developed.

●Object size: Bearing inner diameter 6~25mm, contact angle 15°

●Inner and outer ring non-separable structure

●Universal combination DU, SU correspondence

 

Special series (angular contact ball bearing with sealing ring) (NTN/NSK ball bearing agent)

Since grease is enclosed, the usability is improved, and it is most suitable for maintenance of machine tool spindles.

●High Precision Angular Contact Ball Bearing Standard Series

●Super high-speed angular contact ball bearings, low heat generation series

Corresponding to 70 series and 79 series with bearing inner diameter of 30~100mm

 

Standard series (double row cylindrical roller bearing high rigidity series) (NTN/NSK bearing supplier)

Double row cylindrical roller bearings for high-speed and high-rigidity applications such as machine tool spindles

●The cage has two kinds of copper alloy (MB) and PPS resin (TB)

●There is an E44 type in which the oil holes and grooves of the outer ring are centrally designed in the center of the outer ring width.

Special series (thrust angular contact ball bearing for ball screw support seat) (NTN/NSK bearing agent)

Thrust angular contact ball bearings for machine tool ball screw support

●Contact angle 60°

●A universal combination form suitable for rigidity and life can be selected

●Special grease can be enclosed
