The Link-Belt W216UL is a narrow-style insert ball bearing designed for mounted-bearing housings in agricultural, conveyor, fan, roller, and general industrial applications.

Its spherical outer ring allows the bearing insert to seat inside a compatible spherical housing and accommodate limited initial misalignment between the shaft and housing.

The shaft is secured using an:

Eccentric Cam Locking Collar

This locking method works by rotating the eccentric collar relative to the eccentric extension on the inner ring until the two surfaces wedge together, then securing the collar in position.

This design is particularly suitable for applications with predominantly one-direction shaft rotation.

⚙️ Applications

• Conveyor systems
• Pillow-block bearing units
• Flange bearing units

Approx. Weight: 0.43 lb / 0.20 kg

Load Capability: Primarily radial load with moderate axial-load capability depending on the mounted-bearing arrangement

Shaft Fit: Nominal 1 in shaft

Housing Fit: Must match a compatible spherical-seat insert-bearing housing

Internal Clearance: Verify original Link-Belt specification

Cage: Verify actual Link-Belt production specification

Speed Rating: Verify manufacturer data for exact W216UL execution

Temperature Range: Depends on contact seal material, grease, load, fit, and operating environment

Installation Consideration: Seat the insert correctly in the housing, align the shaft, rotate the eccentric collar in the shaft-rotation direction to lock, secure the collar, and verify alignment before operation

🔁 Equivalent

Suitable cross-reference candidates include:

• Link-Belt W216UL
• SKF YET 205-100
• SKF YET 205-100W
• NTN AEL205-100
• NTN AEL205-100N
• ASAHI SA205-16
• SA205-16
• Timken / Fafnir RA100RRB
• 1 in Bore Eccentric Lock Insert Bearing
• 52 mm OD Insert Bearing

Cross-Reference Comparison

These are strong cross-reference candidates because they belong to the same general 1 inch bore / 52 mm spherical OD eccentric-lock insert-bearing class.

However, a replacement should still be checked for:

• Overall width
• Inner-ring width
• Spherical OD radius
• Eccentric collar geometry
• Seal construction
• Lubrication arrangement
• Internal clearance
• Housing compatibility
• Maximum speed
• Shaft rotation direction requirements

W215UL vs W216UL

The outer body size remains essentially the same, but the shaft bore increases by 1/16 inch.

Therefore, W215UL and W216UL should not be treated as interchangeable unless the shaft diameter is also changed.

(Always verify the complete W216UL dimensions and housing compatibility before selecting another manufacturer's insert bearing.)
