Precision recirculating ball/roller bearings for smooth linear motion in guide systems with high load capacity and minimal friction.
Recirculating ball/roller bearings are precision linear motion components used in linear guide systems, where balls or rollers circulate through a raceway to provide smooth, low-friction linear movement. They consist of a bearing block (carriage), recirculating elements (balls or rollers), end caps, seals, and a guide rail. The design allows infinite travel length by continuously recirculating the rolling elements through a closed path within the carriage, maintaining consistent contact and load distribution.

Recirculating ball bearings use spherical balls as rolling elements, offering lower friction and higher speeds. Recirculating roller bearings use cylindrical rollers, providing higher load capacity and rigidity but slightly higher friction.
Lubrication intervals depend on operating conditions: typically 500-5,000 km of travel. High-speed, high-load, or contaminated environments require more frequent lubrication (every 500-1,000 km), while clean, moderate conditions allow longer intervals (3,000-5,000 km).
Yes, but capacity varies by design. Four-row ball bearings handle moderate moments, while roller bearings with multiple contact points provide better moment load resistance. Always check manufacturer specifications for specific moment load ratings.
