The BCA NPS008RPC is a Ball Insert Bearing – Standard Duty using an eccentric locking collar to secure the bearing to the shaft.

The bearing is associated with BCA / NTN Bearing Corp. of America and uses a narrow-series extended-inner-ring arrangement, where the inner ring projects predominantly to one side to reduce axial installation space.

The eccentric collar locking method works by rotating the collar relative to the eccentric extension on the bearing inner ring and then securing it in position. This provides positive shaft locking without requiring an adapter sleeve.

Key dimensional envelope:

Bore Diameter: 0.5000 in / 12.70 mm

Outer Diameter: 1.5748 in / 40.00 mm

Inner Ring Width: 0.7480 in / 19.00 mm

Overall Width including Locking Collar: 1.1260 in / 28.60 mm

The bearing uses hardened steel construction together with double nitrile rubber sealing, making it suitable for standard-duty industrial environments where dust, dirt, and grease retention are important.

Installation Consideration: Position the bearing correctly, rotate the eccentric collar in the shaft-rotation direction to lock, secure the collar, and confirm shaft/housing alignment before operation

🔁 Equivalent

Suitable replacement or cross-reference candidates should match:

• BCA NPS008RPC
• BCA 1/2 in Eccentric Lock Insert Bearing
• NTN/BCA Standard-Duty Insert Bearing
• 1/2 in Bore Insert Bearing
• 40 mm OD Insert Bearing
• Eccentric Collar Bearing
• Narrow-Series Insert Bearing
• Double-Sealed Insert Bearing
• Mounted Bearing Insert
• Standard-Duty Shaft Bearing

Important Cross-Reference Consideration

A replacement should not be selected from bore size alone.

It should also match:

• 1/2 in bore
• 40 mm OD
• 19 mm inner-ring width
• 28.6 mm overall width
• Eccentric collar geometry
• Inner-ring extension
• Seal type
• Housing compatibility
• Internal clearance
• Speed capability

(Always verify the complete BCA NPS008RPC specification before selecting another brand or insert-bearing family.)
