The Morse ER-16 is a mounted-bearing insert designed around a 1 inch shaft bore and 52 mm outside diameter.

Unlike a standard deep groove ball bearing, the ER-16 incorporates a substantially wider inner ring to provide additional shaft support and room for the locking mechanism.

Nominal dimensions:

Bore Diameter: 1.000 in / 25.40 mm

Outside Diameter: 2.0472 in / 52.00 mm

Inner Ring / Overall Width: 1.3750 in / approximately 34.93 mm

Outer Ring Width: 0.7500 in / approximately 19.05 mm

The bearing is secured directly to the shaft using set screws positioned in the extended inner ring.

This makes installation relatively straightforward and eliminates the need for an eccentric collar or tapered adapter sleeve.

📊 Specifications

Brand: Morse

Model / Bearing Number: ER-16

Alternative Marking: ER16

Product Type: Insert Ball Bearing

Bearing Type: Extended Inner Ring Insert Bearing

Bore Diameter (d): 1.000 in / 25.40 mm

Outside Diameter (D): 2.0472 in / 52.00 mm

Overall / Inner Ring Width: 1.3750 in / approx. 34.93 mm

Outer Ring Width: 0.7500 in / approx. 19.05 mm

Rolling Element: Ball

Number of Rows: Typically single-row ball-bearing construction

Inner Ring: Extended on both sides / wide inner-ring configuration

Locking Method: Set Screw Locking

Set Screw Function: Locks the inner ring directly onto the shaft

Snap Ring / Retaining Feature: ER-series bearings may incorporate an outer-ring retaining ring depending on exact manufacturer execution; verify the physical Morse ER-16 before ordering a replacement

Outer-Ring Geometry: Verify original Morse execution and housing compatibility

Seal / Shield: Verify original Morse specification

Lubrication: Verify factory grease and relubrication arrangement

Internal Clearance: Manufacturer-specific; verify original specification

Cage: Verify actual Morse construction

Load Capability: Primarily radial load with moderate axial-load capability depending on internal geometry and mounted arrangement

Speed Rating: Verify original Morse specification

Temperature Range: Depends on lubricant, seal system, fit, load, and operating environment

Shaft Fit: Nominal 1 inch shaft

Housing Fit: Must match the original ER-series housing or retaining arrangement

Installation Consideration: Confirm bore, OD, inner-ring width, outer-ring width, set screw position, retaining feature, seal arrangement, and housing geometry before installation

🔁 Equivalent

Suitable replacement or cross-reference candidates include:

• Morse ER-16
• Morse ER16
• Sealmaster ER-16
• Rexnord ER16
• Link-Belt ER16
• Timken / Fafnir ER16
• 1 in Bore ER Insert Bearing
• 52 mm OD Insert Bearing
• Extended Inner Ring Bearing
• Set Screw Locking Insert Bearing

Important Cross-Reference Consideration

The ER-16 designation is widely used across several mounted-bearing manufacturers, but it should not automatically be assumed that every ER16 from every brand is 100% interchangeable.

A direct replacement should match:

• Bore = 1 in
• OD = 52 mm
• Inner-ring width = approx. 34.93 mm
• Outer-ring width = approx. 19.05 mm
• Set screw position and thread
• Outer-ring retaining feature
• Seal construction
• Internal clearance
• Lubrication
• Housing geometry
• Speed and load capability

ER-16 vs W216UL

Although both bearings use:

1 inch bore + 52 mm OD

they are structurally different.

Therefore, Morse ER-16 should not automatically replace W216UL, even though Bore and OD match.

The locking system and axial dimensions are fundamentally different.

(Always verify the physical Morse ER-16 bearing and original housing before selecting Sealmaster, Rexnord, Timken, or another ER16 replacement.)
