Oil Injection Pump

ZKL has always exhibited its care and concern for customers by developing a range of value-added products, accessories/tools and instruments that ensure higher efficiency and longer life for its bearings.

One of such developments has been the use of Oil Injection methods for Mounting and dismounting of bearings, especially large – sized ones.

How Oil Injection Works

Oil is injected under pressure (by a reciprocating hand pump)between the shaft and the inner ring of a bearing.

The oil exerts pressure and expands the inner ring at the same time forming a lubricating film. This helps bearings, couplings , fans etc , to slide out easily resulting in scratch – free dismounting.
