Confidence in high-performance machining and efficient assembly

In highly efficient machining centres for tapping and milling operations, operating conditions are

demanding and superior machine reliability is at the top of the agenda. Keeping noise and vibration

levels at a minimum during operation is key to improving confidence in spindle performance.

Achieving outstanding spindle performance in machine tools

and other precision applications where grease lubricated

BT30, BT40, and BT50 spindles are typically used means

high speed capability and a high level of precision, dynamic

accuracy, and thermal stability. Coupled with an increased

focus on reducing noise and vibration levels while improving

production efficiency, the demands on bearings are higher

than ever before.

SKF Silent Series bearings are ideally suited to meet these

demands:

• Extremely quiet operation Specifically designed cages with higher rotational stability greatly reduce noise levels while maintaining low levels of heat generation.

• Efficient assembly and validation process Optimized tolerances and new marking specifications allow easier bearing matching and more efficient mounting.

• Superior machine reliability Effective integral seals prevent the ingress of contaminants and reduce subsequent machine downtime.

• High-speed capability A proven internal design provides low friction, low levels of heat generation, and high stability even at high speeds.

• High system rigidity A compact, high power density design, with improved load sharing across the bearings.

• Full traceability in the manufacturing process A Data Matrix Code marking that gives digital access to relevant product information.

Features of the new SKF Silent Series super-precision range:

• Optimized glass fibre reinforced plastic

cages

• P4B tolerance class, with a narrower

tolerance range on the bore and outside

diameter compared to bearings with a P4

tolerance class

• Run-out according to P4 tolerance class

• Markings on the bearing package

indicating the bearing stand-out

• Data Matrix Code marked on packages and

bearings

The new SKF Silent Series super-precision angular

contact ball bearings are available in two designs:

• High-capacity D design 719 and 70 series, offering a high degree of system rigidity and stiffness, and a high power density for a compact design

Thanks to the optimized cage designs of SKF Silent

Series bearings, operation is quieter and heat generation

is kept to a minimum, allowing spindle manufacturers to

concentrate on what is important – machine performance.

The following diagrams show the excellent performance of

the new SKF Silent Series bearings at low/medium speeds:

• Diagrams 1 and 2 compare noise levels between grease lubricated SKF Silent Series bearings and super-precision bearings with standard cages.

• Diagram 3 compares the temperature rise between grease lubricated SKF Silent Series bearings and super-precision bearings with standard cages.

b e a r i n g s a r e a v ailable as single, universally matchable

bearings.

They are specifically manufactured so that, when mounted in

a random order, but immediately adjacent to each other,

preload within a predetermined range will result without the

use of shims or similar devices.

The bearings have an optimized tolerance range on the bore

and outside diameter, resulting in an improved load sharing

across the bearings when mounted in sets (fig. 1). This not

only improves spindle efficiency, but means less time is spent

during the validation and testing processes to select the

appropriate bearings.

Stand-out value

An indication of stand-out value has recently been added to

SKF single, universally matchable super-precision bearing

markings and their package markings.

The stand-out value, where the stand-out of the back face tb

is practically equal to the stand-out of the front face tf, defines

the position of the side face of the inner ring with respect to

the side face of the outer ring under measuring load F, which

is equal to the preload class desired (fig. 2). The values tb and

tf are close to zero when the measuring load is equivalent to

the preload desired.

For back-to-back and face-to-face arrangements, bearings

with the same stand-out value, but opposite signs, should be

matched. For example, by combining bearings with stand-

outs of –2 and +2, or –1 and +1, the sum of the stand-outs

will be 0. If different stand-outs are combined, for example,

–1 and +2, the sum of the stand-outs will be +1, which will

lead to slightly higher preload in the bearing set.

For tandem arrangements, bearings with the same stand-out

value and the same negative or positive sign should be

matched.

Data Matrix Code

With the Traceability App from SKF, the

most important specifications of SKF

super-precision bearings are close at hand

on smartphones and tablets. The Data

Matrix Code on packages and bearings can

be simply scanned to receive information on the exact

marking of the bearing, and when and where the bearing

was manufactured.

The App is programmed not only to contribute to the trace-

ability of each bearing, but also to facilitate the grouping of

several bearings. This is particularly helpful when matching

a pair of bearings.

For more information about the markings on bearings and

packages, refer to pages 8 and 9.

established from the outer ring face.
