The Link-Belt / Rexnord B22439-HL is a double-row spherical roller bearing insert designed for heavy-duty mounted-bearing service.

Its spherical roller geometry provides substantially greater radial-load capability than typical insert ball bearings and allows the bearing arrangement to tolerate limited angular misalignment between the shaft and housing.

Nominal dimensions:

Bore Diameter: 2.4375 in / 61.91 mm

Outside Diameter: 4.3307 in / approximately 110.00 mm

Overall Width: 3.5000 in / approximately 88.90 mm

The model belongs to the B22400 Series and is larger in shaft-bore size than the previously referenced B22435-HL, making it suitable for larger shafts and heavier industrial equipment.

The bearing uses a concentric locking collar arrangement, allowing the inner ring to be secured concentrically around the shaft rather than relying only on direct set-screw contact at isolated points.

⚙️ Applications

Primary Load Capability: Heavy radial load

Axial Load Capability: Spherical roller bearings generally support axial loading in addition to radial loading, but the exact allowable value for B22439-HL should be confirmed from Rexnord engineering data

Misalignment Capability: Suitable for limited angular misalignment inherent to spherical roller bearing geometry

Shaft Locking System: Spring / Concentric Locking Collar

Locking Principle: Concentric locking around the shaft for secure shaft engagement

Seal Arrangement: Exact B22439-HL seal construction should be verified from the original Rexnord specification or physical bearing

Lubrication: Verify original grease and relubrication arrangement

Internal Clearance: Manufacturer-specific; verify original specification

Cage: Verify original Link-Belt / Rexnord construction

Dynamic Load Rating: Verify manufacturer specification

Static Load Rating: Verify manufacturer specification

Housing Compatibility: Must match the appropriate Link-Belt / Rexnord housing and B22400-series mounting arrangement

Installation Consideration: Confirm shaft diameter, OD, overall width, collar arrangement, seal construction, housing geometry, lubrication, and operating speed before installation

Relationship to B22435-HL

The B22439-HL is a larger member of the same general B22400-series family.

The larger bore means the B22439-HL should not be treated as interchangeable with B22435-HL even though both belong to the same broad series.

Important Cross-Reference Consideration

A replacement should match:

• Bore diameter
• Outside diameter
• Overall width
• Inner-ring geometry
• Locking collar design
• Seal arrangement
• Outer-ring profile
• Internal clearance
• Cage design
• Load ratings
• Maximum speed
• Housing compatibility

The suffix HL should be retained in all cross-reference searches because it may identify a specific Link-Belt / Rexnord execution.

(Always verify the complete B22439-HL bearing and housing specification before selecting another manufacturer's replacement.)
