⚙️ Features & Benefits

✔ High radial load capacity: The tapered roller design provides a large contact surface which enhances radial load handling.

✔ Combined radial + axial load support: The taper geometry is well suited to applications where axial thrust must be supported in one direction.

✔ Separable design (cone + cup): Allows flexibility in mounting, preload adjustment and ease of replacement.

✔ Imperial size series: Useful for equipment designed to inch-dimension standards.

✔ Reliable brand & design: Timken is widely regarded for quality bearings under heavy duty conditions.

Typical Applications

Wheel‐hubs and drive axles in vehicles and equipment where axial thrust and radial loads exist.

Gearboxes, transmissions, and differential systems requiring axial location of shafts.

Industrial equipment such as drives, rollers or spindles which experience combined loads and need robust bearing support.

Machinery in mining, aggregate, construction or material handling where imperial bearings may be specified.

Specification / Ordering Tips

When ordering 1988/1922 make sure you have both components (cone 1988 + cup 1922) since they function as a matched set.

Check axial load direction – this bearing supports thrust in one direction; if bidirectional axial loading is required, a paired arrangement or alternate series may be needed.

Verify shaft/housing fits, preload or clearance settings, and lubrication for the expected load and speed conditions.

Because it’s an inch‐series bearing, verify you are replacing or designing for the correct bore (≈28.575 mm) and OD series.
