Description
Overview:
The Worm Shaft Oil Seal is a Genuine Altrad/Belle component designed for the gearbox on Belle Minimix 150 (1989-Oct 2004) and Minimix 140 mixers. It sits on the worm shaft to contain gearbox oil and keep out dust and slurry, helping the worm and pinion stay correctly lubricated. Built from oil‐resistant elastomer with a rigid metal reinforcement and a spring-loaded sealing lip, it offers dependable sealing under site conditions. The seal measures 20 mm x 42.5 mm x 10 mm (0.79 inches x 1.67 inches x 0.39 inches), matching the original specification for a precise fit. Using the correct seal helps maintain smooth drum rotation, reduces wear, and supports long service life in both trade and DIY use.
