Oil-Air Lubrication for Wire Rod Mill Pinch Roll and Laying Head Bearings

Release time:

2021-10-27

The pinch roll and laying head are important components in the finishing and coiling sections of a high-speed wire rod mill. They work under high rotational speed, mechanical vibration and continuous production conditions. Their bearings require reliable lubrication to maintain stable material transfer and accurate wire rod forming.

Operating Conditions and Lubrication Challenges

Pinch roll and laying head bearings may experience:

High rotational speed;
Repeated mechanical loads;
Vibration and shock;
Elevated operating temperature;
Dust and metal scale;
Limited maintenance time during continuous production.

If bearing lubrication is unstable, friction and temperature may increase. In severe cases, bearing damage can affect wire rod conveying, coiling quality and production continuity.

Why Consider Oil-Air Lubrication?

Oil-air lubrication supplies a controlled quantity of oil to the bearing through a combination of lubricant and compressed air. This method is suitable for applications requiring accurate lubricant dosing and stable delivery.

The main potential benefits include:

Precise oil supply to each lubrication point;
Continuous replenishment of fresh lubricant;
Reduced risk of over-lubrication;
Supporting cooling of high-speed bearings;
Reduced lubricant consumption;
Centralized control and easier maintenance.

The system design must consider the bearing arrangement, lubrication point location, rotational speed, lubricant type, temperature and pipeline routing.
