48H381 - Walter 48-H-381 Replacement Needle Bearing for Line-Mate III

Precision OEM Component for Walter Tools

The Walter 48-H-381 Needle Bearing is a critical internal component designed specifically for the transmission assemblies of Walter Surface Technologies' premium finishing tools. As a genuine OEM part, it guarantees the exact dimensional tolerances required for the smooth operation of high-torque equipment like the Line-Mate III and Big-Buff III.

Needle bearings are essential for handling high radial loads in compact spaces within power tool gearboxes. This specific bearing is manufactured from high-grade hardened steel to resist wear and deformation under the thermal and mechanical stresses of continuous industrial use. Replacing a worn bearing with this authentic Walter component ensures that the drive spindle remains perfectly aligned, preventing damage to adjacent gears and housing components.

Failure to replace a compromised bearing can lead to increased friction, overheating, and catastrophic failure of the tool's drive mechanism. The 48-H-381 is engineered to restore the original performance characteristics of your equipment, maintaining the smooth, vibration-free operation that Walter tools are known for. It is recommended to inspect surrounding components such as seals and gears during installation to ensure a comprehensive repair.
