What is the Difference Between Grease and Lubricating Oil?
1 Answers
Lubricating oil and grease differ in the following aspects: 1. Adhesion properties: When the friction part is in a static state, grease can maintain its original shape without automatically losing due to gravity, nor will it slide off vertical surfaces or leak through gaps. This characteristic makes it particularly suitable for friction parts that are frequently started and stopped, parts where replenishing grease is difficult, and open or poorly sealed areas. 2. Temperature range: Grease has a wider working temperature range compared to lubricating oil. 3. Pressure resistance: Grease has much stronger adsorption capability on metal surfaces than lubricating oil and can form a more robust oil film, capable of withstanding higher working loads. This is due to the large amount of polar substances contained in grease.
