Axial/radial bearings YRT 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, such as rotary tables, face plates, milling heads and reversible clamps .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.

 

For standard applications with low speeds and small operating durations, such as indexing tables and swivel type milling heads, the most suitable bearing is generally series YRT,. These bearings are available in two axial and radial runout accuracies. 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. Axial angular contact ball bearings LYNB are particularly suitable for high speed applications with long operating duration. They are characterised by high tilting rigidity, low friction and low lubricant consumption.

 

     ▲   The design’s of all these YRT Bearings are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
