INA YRT, YRTC, YRTS and ZKLDF bearings

INA 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.

Simple mounting due to fixing holes
Due to the fixing holes in the bearing rings, mounting of the units is very simple. After mounting, the bearings are radially and axially preloaded. The mounting dimensions of all series are identical.

INA Axial/radial bearings YRT, YRTC and YRTS

YRT and YRTC suitable for low speeds and small operating durations
For standard applications with low speeds and small operating durations, such as indexing tables and swivel type milling heads, the most suitable bearings are series YRT and YRTC.

YRTS suitable for high speeds with low frictional torque
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 combination with torque motors.
For higher running accuracy requirements, both series are also available with restricted axial and radial runout.

Axial angular contact ball bearings ZKLDF

Suitable for very high speeds and long operating durations
Axial angular contact ball bearings ZKLDF are highly suitable for high speed applications with long operating duration. They are characterised by high tilting rigidity, low friction and low lubricant consumption.

INA axial angular contact ball bearings are particularly suitable for precision applications involving combined loads. Their preferred areas of use are bearing arrangements in rotary tables with a main spindle function, for example in combined milling and turning, as well as in milling, grinding and honing heads and in measurement and testing equipment.
