Installation and maintenance guidelines

For optimal bearing performance, follow these recommendations:

• Mount the housing on a clean, flat, and corrosion-protected surface.

• Tighten bolts evenly according to manufacturer torque specifications.

• Align the shaft precisely to avoid axial stress and premature wear.

• Periodically inspect seals and grease condition; in non-greaseable variants, factory lubrication covers the entire service life.

• Avoid excessive vibration or overload to maximize bearing longevity.

Following these practices ensures consistent operation in conveyors, automation systems, and light-industrial drives.
