3900A2RS Double Row Angular Contact Ball Bearing, Load Capacity, Smooth Rotation, Sealed

This listing covers 1 piece of double row angular contact ball bearings in the 3900 to 3907A2RS family. Each bearing is a sealed 2RS type, designed to support combined radial and axial loads with accuracy. The 2RS seals on both sides protect the bearing from dust and help retain lubrication, contributing to longer service life with reduced maintenance. The double row design provides stable rigidity and smooth rotation in applications with limited space. Key attributes Type: double row angular contact ball bearing Seals: 2RS on both sides Model range: 3900, 3901, 3902, 3903, 3904, 3905, 3906, 3907A2RS Mounting compatibility: fits standard shaft and housing interfaces; exact dimensions vary by model Material: typically bearing steel (general industry standard for this bearing type) Performance: supports radial and axial loads in both directions; suitable for speed operation with proper lubrication; low friction and reliable operation Lubrication and seal retention: sealed to retain lubricant and prevent contamination Packaging: sold as 1 piece per unit Applications and use cases Spindle support in milling and turning machines where precise shaft alignment and rotational stability are required Joints and motion axes in robotic arms and automation equipment demanding smooth, accurate movement Drive system components in gearboxes and conveyors where space is constrained and contamination resistance is important Dimensions and compatibility notes Dimensions (bore, outer diameter, width) vary by model within the 3900 to 3907A2RS range. Refer to the specific model code for exact measurements. Suitable for applications requiring a sealed, double row angular contact bearing with robust load handling and reduced maintenance. Installation and maintenance tips Clean mounting surfaces before installation Use proper tools and alignment to avoid bearing misfit or damage Ensure adequate lubrication according to the application and manufacturer recommendations Keep bearings sealed from contaminants when in service; seals if damaged Notes This description reflects the 1 piece offering for models 3900, 3901, 3902, 3903, 3904, 3905, 3906, and 3907A2RS in the double row angular contact bearing family Exact dimensions and tolerances depend on the specific model chosen; confirm the model code to match your application requirements
