Schaeffler 619-2RSR Series Ball Bearing, 30mm Outside Diameter, 17mm Inside Diameter - 61903-2RSR-HLC


This ball bearing is a sealed single-row deep-groove radial bearing designed to support rotational loads in Compact assemblies. It operates across a wide temperature range and is suitable for applications requiring sealed protection and steel construction while maintaining high rotational capability.

Features and Benefits:


• Sealed construction limits contamination and reduces maintenance
• Steel cage offers Durable retention under continuous operation
• Internal clearance CN provides predictable axial and radial play
• Static load capacity 2.56 kN resists high stationary loads
• Dynamic load capacity 4.59 kN supports sustained radial loading
• Limiting speed 12,700 r/min enables high-speed miniature operation

Applications


• Suitable for precision motor shafts in Compact drives
• Ideal for small gearbox and transmission bearings
• Used with rotary actuators in automation equipment
• Can be used for wheel hubs in lightweight mechanisms
• Appropriate for instrumentation spindles requiring sealed units

What shaft and housing interfaces are required for correct mounting?


Minimum shaft shoulder diameter must allow a 19 mm seating and housing shoulder must not exceed 28 mm to ensure correct axial seating and ring engagement.

What operating temperatures can be expected without seal compromise?


The bearing functions from −30 °C up to 100 °C while retaining sealing integrity for typical industrial environments.

How should fillet and chamfer dimensions be accommodated during design?


Design fillet radii no larger than 0.3 mm and provide a minimum chamfer depth of 0.3 mm to avoid interference with ring edges.

What is the typical mass to consider in rotating assemblies?


The component mass is 17 g, which should be included when calculating rotor inertia and balance.

Which running clearance and fatigue limit relate to life predictions?


The internal clearance classification CN and a radial fatigue load limit of 150 N are the parameters used for bearing life and endurance calculations.
