Oil Seal U Type Basic Type UD Type

Oil Seal U Type Basic Type UD Type

A U type oil seal is used if it is necessary to eliminate foreign materials entering from outside. As common as type A in rotation applications.

[Features]
· An oil seal seals off lubricant leakages in bearings. By preventing the penetration of dust and water and other external objects, the seal helps protect the bearings.
· Bearing part precision is maintained and a reduction in lubricating oil usage provides significant benefits in terms of bearing corrosion repair costs, offsetting seal equipment costs.
· Essential for driving shafts for the purpose of sealing in fluids and gases, in addition to lubricant oil.
· Form factor is small making installation and removal easy without requiring a lot of space, which is useful in making equipment small and lightweight
