SKF Single Row Tapered Roller Bearing – BT1B 328612 C/QCL7C (40.988 × 68 × 17.5 mm)

Genuine SKF single row tapered roller bearing, part number BT1B 328612 C/QCL7C. Designed to handle combined radial and axial loads with low friction in demanding gearbox and transmission applications.

Part Number: BT1B 328612 C/QCL7C

Brand: SKF (Sweden)

Bore Diameter: 40.988 mm

Outside Diameter: 68 mm

The inner ring assembly (inner ring, rollers and cage) can be mounted separately from the outer ring, making fitting and dismounting straightforward. Applying a preload by mounting two single row bearings back-to-back achieves a rigid, play-free installation.

What is a tapered roller bearing?

Tapered roller bearings use conical rolling elements to support combined radial and axial (thrust) loads simultaneously. They are commonly used in manual gearbox output shafts, final drives and differential pinions where both load types are present.

What does the QCL7C suffix mean on SKF bearings?

The QCL7C suffix denotes a specific internal clearance and cage specification — it is important to use the correct suffix variant to ensure correct preload and bearing life in the application.

Is this a genuine SKF bearing?

Yes — this is a genuine SKF-manufactured bearing, not a substitute. SKF is one of the world’s leading bearing manufacturers, known for precision and quality used by OEM gearbox manufacturers.

Do I need to replace this bearing in pairs?

For differential pinion and gearbox shaft applications, tapered roller bearings are typically installed in matched opposing pairs. If one bearing has failed, inspect the opposing bearing for wear and replace both where possible.

What grease or oil should I use with this bearing?

In gearbox applications this bearing will be lubricated by the gearbox oil. Ensure the correct gearbox lubricant grade is used and the oil level is correct after assembly.
