Precision-Engineered UV Groove Deep Groove Ball Bearings for Optimal Performance
High-grade chrome steel construction ensures durability and smooth operation under heavy loads, with precision grinding for minimal friction and noise. Sealed variants (W4ZZ, W4-2RS) offer dust/water resistance, ideal for humid or dirty environments like industrial machinery and conveyor systems.
Ultra-thin design (15x59.94x19.05mm) fits compact spaces in pulley systems, guide rails, and track rollers, enhancing linear motion efficiency. RM4SSX stainless steel option resists corrosion in food processing or marine applications.
Pre-lubricated for maintenance-free use, reducing downtime in automation equipment and CNC tools. Tight tolerance (ABEC-1 standard) guarantees consistent performance in high-speed scenarios like 3D printers or packaging lines.
Direct factory pricing enables bulk purchases for OEMs or MRO suppliers without sacrificing quality. Global shipping available for logistics, robotics, and automotive assembly line projects.
