Installation Instructions
The installation of Timken EC series spherical roller bearing solid-block housed units requires ensuring the shaft is clean and of proper diameter.

Lubrication Specifications
Factory-prelubricated with NLGI No. 2 lithium-complex grease, these units should be relubricated with compatible grease.

Warnings and Safety
Proper maintenance and handling are critical to avoid risks of injury or equipment failure.

Installation Methods
Timken provides two methods for installing housed units: the Axial Drive-Up Method and the Tang Counting Method.

Axial Drive-Up Method

Clean components and apply a thin oil film.
Position the open-end cover/seal on the shaft, followed by the adapter sleeve and housed unit.

Tang Counting Method

Similar initial steps as the Axial Drive-Up Method.

Lubrication
Timken housed units are prelubricated with NLGI No. 2 lithium-complex grease, suitable for temperatures from -40°C to 177°C.

Conversion Between Expansion and Fixed Units

For converting from expansion to fixed, tighten the retaining nut and set screw.

Warnings
Proper maintenance and lubrication are critical to prevent overheating and potential hazards in explosive environments.
