Roller Bearing

About Roller Bearing

Roller Bearings use steel rollers between plates to allow horizontal sliding in one direction. Suitable for bridges with high longitudinal expansion, such as steel truss or railway structures. While enabling linear motion, they restrict lateral movement. Often used with rocker bearings, they require periodic inspection to prevent corrosion or wear-related failures.

Roller Bearing

Roller Bearing

Roller Bearings consist of steel rollers placed between upper and lower bearing plates, allowing free horizontal movement in the direction of the rollers. They are ideal for structures with large longitudinal movement. Used where significant expansion/contraction is expected. Common in old railway bridges and steel truss structures. Allow linear translation but restrict lateral movement. Often combined with rocker bearings for enhanced performance. Need regular inspection to prevent dust and corrosion damage.
