Axial angular contact ball bearings
Features Axial radial bearings YRT, YRTC and YRTS and axial angular contact
ball bearings ZKLDF are ready-to-fit high precision bearings for
high precision applications with combined loads. They can support
radial loads, axial loads from both sides and tilting moments without
clearance and are particularly suitable for bearing arrangements
with high requirements for running accuracy.
Due to the fixing holes in the bearing rings, the units are very easy
to fit.
The bearings are radially and axially preloaded after fitting.
The mounting dimensions of all series are identical.
Axial/radial bearings YRT in the size range of d = 580 mm to
d = 1 030 mm have been replaced by YRTC.
Compared with the predecessor product YRT, these bearings have
higher rigidity, a higher limiting speed and lower bearing friction.
With angular measuring
system
Axial/radial bearings are also available with an absolute value
angular measuring system or have systems with pitch-coded
reference marks. The measuring systems can measure angles to
an accuracy of a few angular seconds by non-contact means,
see page 44 and page 78.
Areas of application For standard applications with low speeds and small operating
durations, such as indexing tables and swivel type milling heads,
the most suitable bearings are generally series YRT and YRTC,
Figure 1.
For the bearing arrangements of direct drive axes, there is the
series YRTS. Due to their high limiting speeds and very low, uniform
frictional torque across the whole speed range, these bearings are
particularly suitable for combtion with torque motors, Figure 1.
For higher accuracy requirements, these bearings are also available
with restricted axial and radial runout accuracy.
Axial angular contact ball bearings ZKLDF are particularly suitable
for high speed applications with long operating duration, Figure 1.
They are characterised by high tilting rigidity, low friction and low
lubricant consumption.
Axial/radial bearings Axial/radial bearings YRT, YRTC and YRTS have an axial and
a radial component.
The axial component comprises an axial needle roller or cylindrical
roller and cage assembly, an outer ring, L-section ring and shaft
locating washer and is axially preloaded after fitting. The radial
component is a full complement cylindrical roller set in YRT and
a cage-guided, preloaded cylindrical roller set in YRTC and YRTS.
The outer ring, L-section ring and shaft locating washer have fixing
holes.
The unit is located by means of retaining screws for transport and
safe handling.
Sealing Axial/radial bearings are supplied without seals.
Lubrication The initial greasing of YRTS corresponds to the grease Arcanol
LOAD150 and, in the case of YRT and YRTC, to the grease Arcanol
MULTITOP. The bearings can be lubricated via the outer ring and
L-section ring.
Axial angular contact
ball bearings
Axial angular contact ball bearings ZKLDF comprise a single-piece
outer ring, a two-piece inner ring and two ball and cage assemblies
with a contact angle of 60°. The outer ring and inner ring have
fixing holes for screw mounting of the bearing on the adjacent
construction.
The unit is located by means of retaining screws for transport and
safe handling.
Sealing Axial angular contact ball bearings have sealing shields on both
sides.
Lubrication The initial greasing of current axial angular contact ball
bearings ZKLDF (Generation B) corresponds to the grease Arcanol
MULTITOP. The bearings can be relubricated via the outer ring.
