The MRC RRH1012BRR is an industrial insert ball bearing intended for use in compatible mounted-bearing housings.

Its most important distinguishing features are:

• 3/4 inch bore
• Wide inner ring
• Set screw shaft locking
• Spherical outer ring
• Double labyrinth sealing
• Non-relubricatable construction

The spherical outer ring allows the insert to seat in a compatible housing and accommodate limited misalignment between the shaft and housing assembly.

The extended / wide inner ring provides the axial length required for the locking system and mounted-bearing geometry.

⚙️ Applications

• Conveyor systems
• Fans and blowers
• Agricultural machinery
• Material-handling equipment
• Packaging machinery
• Roller assemblies
• Light industrial drives
• Shaft-support systems
• OEM mounted-bearing units
• Maintenance and replacement

• 3/4 in Bore Insert Bearing
• 19.05 mm Insert Bearing
• 47 mm OD Insert Bearing
• Wide Inner Ring Bearing
• Set Screw Locking Insert Bearing
• Double Labyrinth Seal Bearing

Important Cross-Reference Consideration

A replacement should not be selected only from:

19.05 mm bore × 47 mm OD × 14 mm outer-race width

because RRH1012BRR also depends on:

• Wide inner-ring length
• 1.22 in length through bore
• Set screw location
• Set screw size/thread
• Spherical outer-ring geometry
• Double labyrinth seal design
• Housing compatibility
• Internal clearance
• Lubrication arrangement

A standard deep-groove bearing with 19.05 × 47 × 14 mm dimensions would not automatically reproduce the mounted-bearing geometry of this insert.

(Always verify the actual RRH1012BRR bearing and housing before selecting a substitute.)
