ZVL 61905 2RS Thin Section Deep Groove Ball Bearing 25x42x9

Overview

The ZVL 61905 2RS is a premium single-row thin section deep groove ball bearing designed for applications where compact dimensions, low weight and high rotational speeds are required. As a member of the 61900 Series, it features a reduced cross-section while maintaining excellent running accuracy and durability.

The 2RS suffix indicates contact rubber seals on both sides of the bearing. These seals effectively prevent dust, moisture and contaminants from entering while retaining the factory-filled grease inside. The bearing is therefore pre-lubricated, maintenance-free and ready for installation.

Industrial Applications

The ZVL 61905 2RS is widely used in:

• Electric motors
• Industrial pumps
• Medical equipment
• Robotics
• Precision gearboxes
• Conveyor systems
• Packaging machinery
• Textile machinery
• Agricultural equipment
• General industrial machinery

Construction

The bearing features:

• Single-row deep groove ball bearing
• Thin section (61900 Series)
• Contact rubber seals (2RS) on both sides
• Deep raceway geometry
• Pressed steel cage
• Factory-filled grease
• Maintenance-free operation
• High-speed capability
• Low friction and low noise

The optimized raceway design enables the bearing to support high radial loads together with moderate axial loads in both directions.

Material

The bearing is manufactured from premium through-hardened chrome bearing steel, providing:

• Excellent fatigue resistance
• High wear resistance
• Superior dimensional stability
• High running accuracy
• Long service life

The rubber seals provide reliable protection against contamination while preserving lubrication throughout the bearing's service life.
