Simple internal structure, low friction and high limiting speed, mainly bear radial direction load. Deep groove ball bearing can obtain angular contact capability when increasing radial clearance, to take combined load of both axial and radial directions. When the thrust ball bearing is not appropriate for some high speed applications, deep groove ball bearing may be an alternative choice to afford axial loads.

In angular contact ball bearing range, RHD is mainly focusing on high precision and signal row type. Available size range from 2mm ID to 90mm OD, and the precisions include ABEC5, ABEC7 and ABEC9. By excellent rotating speed, great rigidity, long effective life and low vibration, RHD angular contact ball bearings are widely applied on high precision and low noise equipments and machine tools.

High Precision, low vibration and low noise, extremely high speed, excellent quality.

Inch series ball bearings are sized with units and tolerance of British system, appropriate for inch size equipments, commercial machines tools and small rotating machinery. Recently, requirement of miniature size, light and thin bearing in inch size is stably increasing.

High precision bearings are RHD’s major business, our high precision instrument bearings and electrical motor bearings take high share in the market with brilliant customer feedbacks.
