Production Introduction

 

Single Row Cylindrical Roller Bearings Are Separable Bearings, Which Are Easy To Install And Disassemble, Both Rings Can Be Tightly Fitted, And The Modified Contact Line Between The Rollers And Raceways Can Reduce Stress Concentration.

Basic Type
The Types Of Cylindrical Roller Bearings Are Divided According To Their Rib Form.
The NU Type Bearing Has Two Ribs On The Outer Ring And No Ribs On The Inner Ring. The Inner Ring Of The N-Type Bearing Has Two Ribs, And The Outer Ring Has No Ribs.

 

Cylindrical Roller Bearing Features:
1. The Roller And The Raceway Are In Line Contact Or Trimmed Line Contact, And The Radial Bearing Capacity Is Large, Which Is Suitable For Bearing Heavy Loads And Impact Loads.
2. The Friction Coefficient Is Small, Suitable For High Speed, And The Limit Speed Is Close To That Of Deep Groove Ball Bearings.
3. N Type And NU Type Can Move Axially, Can Adapt To The Change Of Relative Position Between Shaft And Shell Caused By Thermal Expansion Or Installation Error, And Can Be Used As Free End Support.
4. The Processing Requirements For The Shaft Or Seat Hole Are High. After The Bearing Is Installed, The Relative Deflection Of The Outer Ring Axis Should Be Strictly Controlled To Avoid Contact Stress Concentration.
5. The Inner Ring Or Outer Ring Can Be Separated For Easy Installation And Removal.

Main Uses: Large And Medium-Sized Electric Motors, Locomotives, Machine Tool Spindles, Internal Combustion Engines, Generators, Gas Turbines, Reduction Boxes, Rolling Mills, Vibrating Screens, And Hoisting And Transporting Machinery.
