Assembled complete units (housing + bearing) make up the heavy duty UCP 300 Series. The housings are Cast Iron and the bearings are set screw locking for easy installation.

Slight change of perspective, this is a side view of all 20 housings. Pictured here, the largest housing and bearing (121.9kg combined) and smallest housing and bearing (1.9kg combined).
