LYRA，Custom slewing drive and slewing bearing manufacturers

Precision turntable bearings

LYRA bearing YRT series and YRTS series are precision slew bearings. According to the requirements, the accuracy level can reach P2 level, P4 level, P5 level. They are mainly used for machine tool slewing bearings. ZKLDF series bearings are double row angular contact bearings, mainly used for precision turntables, ball screws, milling and grinding head rotation, etc.

YRT Series

Double row axial rolling elements and single row radial rolling elements are guided by copper cages to form a precise bearing system. Supports axial, radial and overturning moment loads, and is axially and radially preloaded after installation.

The YRT series is suitable for slow and limited duration operations
