TVN carriage bearing housings
Unsplit housings for self-aligning ball bearings with a cylindrical bore, supplied as floating bearings.
TVN housings are unsplit and intended for self-aligning ball bearings with a cylindrical bore. They are supplied as floating bearings as standard.
A locating arrangement is achieved by inserting fixing or intermediate rings.
Sealing is by felt strip. The body is grey cast iron GG 20. The manufacturer recommends a high grade grease; an R 1/8 grease hole is provided for later regreasing.
