Ball bearings are critical components in a myriad of mechanical systems and machinery, from large industrial plant machines to small appliances.
Bearings enable efficient and streamlined movement by cutting friction between moving parts and facilitating a smoother operation. To perform properly and stay damage free, ball bearings require correct lubrication. Without this essential inclusion, bearings can fail prematurely, resulting in expensive repairs and mechanical downtime.
Grease is the advised lubricant for around 80 per cent of rolling bearings, as it simplifies maintenance and remains in place. It creates a defensive seal against contaminants and works as a semi-solid that gradually thins out to supply lubrication during shear. It also protects metal bearings from rust and other forms of corrosion.
Synthetic oil is also used to lubricate bearings as it offers superior viscosity stability, resistance to chemical breakdown and exceptional temperature resistance.
With multiple lubricants available to serve bearings, it’s important to match the right type to a specific application. Below, we provide a guide to help users find the best products to match the needs of their bearings.
Lithium complex grease
The most used general-purpose grease, lithium complex grease is a superb solution for standard wheel bearings and those fitted in agricultural equipment. This grease is also suitable for bearings working under moderate operating conditions.
Polyurea grease
Respected for its superior resistance to oxidation and high-temperature stability, polyurea grease is a high-performance premium lubricant that features non-soap polyurea compounds as a thickening agent, rather than the metal soaps used traditionally (like lithium and calcium). Its advanced attributes make it a match for bearings in electric motors and equipment working at high speeds.
Synthetic oils and greases
Man-made lubricants, synthetic oils and greases are specifically formulated to cope with extreme operating conditions. As such, they are ideal to lubricate bearings when they are working under high-speed demands and temperatures, where thermal breakdown is a significant risk.
Calcium sulphonate grease
Offering outstanding water resistance and dependability under heavy loads, calcium sulphonate grease is the go-to solution for bearings in equipment working in marine environments and in heavy-duty industrial environments, where there is risk of corrosion and rust.
