SL185007 Precision Cylindrical Roller Bearings For Automobile Gearbox

 

 

Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to  balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are  distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity  and are suitable for high speeds. Doublerow cylindrical roller bearings have high radial rigidity and are  used primarily for precision machine tools.

 

 

Pressed steel (with or without tins or fins) or machined brass cages are generally used, but sometimes molded polyamide cages are also available depending on the application. Cylindrical Roller Bearings are also available without cages with a full complement of rollers. This allows even higher loads but at the expe nse of speed. 

 

Depending on the series as defined below a number of cylindrical roller bearings have no ribs on either  the inner or outer ring, so the rings can move axially relative to each other which can be used as freeend  bearings.

 

 

Single row cylindrical roller bearings are also manufactured with snap ring grooves on the outer rings. This design simplifies the bearing joint as the bearings are located into the housing by means of the snap rings. The snap ring groove and snap rings are in accordance with IS0 464.

 

 

There are different types designated NU, NJ, NUP, N, NF for single-row bearings, and NNU, NN for  doublerow bearings depending on the design or absence of side ribs. AST’s cylindrical roller bearings  come in the following series with various cage designs and Metric dimensions:

 

 

Design features

 

 

1. Optimized design in ribs and rollers to enhance the axial load capacity

2. Optimized design in the geometric surface between rollers and raceway to balance the radial load  distribution

3. Limit the width of raceway undercut, increase the contact area between raceway and rollers and  enhance the radial load capacity

4. High standard material, strictly control the element content, e.g. Ti<30ppm

5. Low noise design, reaches to V1 grade noise level, contributes to the quieter running of automobile  engine and gearbox.
