Product Description▼
The KOYO 68149 Tapered Roller Bearing (commonly referenced as L68149/L68110) is a precision engineered single-row tapered roller bearing designed to support heavy radial loads and axial thrust loads in one direction. Manufactured by KOYO (JTEKT) with quality materials and heat treatment, this bearing delivers robust performance and long service life in rotating systems.
Product Overview
Tapered roller bearings like the KOYO 68149 use a combination of tapered rollers and matching tapered raceways. This geometry allows them to handle radial forces and axial thrusts simultaneously, making them ideal for applications involving heavy loads, impact forces, and motion with a thrust component.
This bearing is sold as a cone (inner ring + rollers + cage) combined with a cup (outer ring) — often referenced together (L68149/L68110). The separable design allows precise fitting and adjustment when installed.

Applications & Uses
KOYO 68149 (L68149/L68110) is widely used in mechanical systems where a compact tapered roller bearing of this dimension is required:
🛠 Industrial & Mechanical Equipment
-
Gearboxes and reducers
-
Conveyor drives
-
Machine tool spindles
-
Heavy equipment shafts
-
Agricultural machinery
(Dimensions and suitability must be matched to your machine’s requirements.)
🚗 Automotive & Vehicle Systems
Note: Tapered roller bearings like this one are dimension-specific and not tied to a fixed list of vehicle makes/years unless referenced by an OEM part number. For automotive fitment:
-
Check the original bearing code or part number on the vehicle.
-
Match bearing dimensions (34.98 × 59.975 × 15.875 mm) and load requirements.
-
Use the vehicle’s service manual or parts catalog to confirm correct application.
Common automotive uses of tapered roller bearings in the same size range include:
-
Trailer wheel hubs
-
Light machinery steering knuckles
-
Transmission intermediate shafts
Always verify fitment with bearing dimensions before ordering.

When searching alternatives, always match dimensions and load ratings first before substitution.
Fitment & Installation Tips
✔ Match dimensions: ID, OD, and width must exactly match your application’s requirement.
✔ Pair with correct cup: Ensure you order both the cone (68149) and cup (68110) for installation.
✔ Use proper lubrication: Grease or oil lubrication will depend on speed and operating conditions.
✔ Confirm load & speed: Make sure bearing ratings meet the forces and speeds in your system.
