Oscillating bearings - Import export

Pivot pins are found on shutoff devices such as spherical valves, butterfly valves, hollow jet valves and plunger valves. These valves are generally used for opening and closing and occasionally to control the flow rates by oscillating movement. The greaselubricated sliding bearing is protected against water infiltration by a seal on the inside. The seal also prevents the grease leaking into the inside to prevent water contamination. The MANOY® system seal WP, type 418, was developed for this application. To prevent leakage of grease from greased bearings, the unidirectional MANOY® system seal WP, type 456, is also installed.
