Lubrication is the "blood" of bearings, and choosing the right method can double the lifespan of bearings. Enkefu Bearing Technology Department has summarized the two mainstream lubrication methods and selection strategies for bearing rotation for you.

1、 Two mainstream methods

Grease: a worry free choice

Features: Simple structure, no need for oil supply system, and the grease itself has a sealing and dustproof effect.

Advantages: Low maintenance cost and long-lasting durability with a single filling.

Applicable to low to medium speeds, harsh environments (dust/humidity), or places where maintenance is inconvenient (such as agricultural machinery, conveyor belts).

Oil lubrication: the choice of performance

Features: Excellent heat dissipation, low friction resistance, and the ability to remove wear particles.

Advantage: Adapting to high-speed and high-temperature working conditions, it is the guarantee of precision equipment.

Applicable: High speed motors, precision machine tool spindles, and large reducers.

2、 Advanced gameplay of oil lubrication

Oil bath/drip oil: suitable for medium and low-speed conventional equipment.

Fuel injection/oil and gas: suitable for ultra high speed and high-precision spindles (such as machining centers), with extremely high heat dissipation efficiency.

3、 NKFB Expert Selection Formula

Low speed, high dust, difficult to maintain - choose [grease lubrication]

High speed, high temperature, heavy load - choose [oil lubrication]
