Roller bearings are key components in transmission machinery equipment that support rotating parts, reduce friction, and ensure rotational accuracy. They have automatic centering function and are mainly divided into two types: self-aligning ball bearings and self-aligning roller bearings
Structure and Classification
Self aligning ball bearing: compensates for installation errors through spherical structure, suitable for bearing radial loads and bidirectional axial loads, commonly used in industries such as metallurgy and rolling mills
Self aligning roller bearing: adopting double row roller design, suitable for heavy load working conditions, allowing the self aligning angle to be 1-2.5 degrees, but the working speed is relatively low
Material characteristics: It needs to have high contact fatigue strength, wear resistance, and rust prevention performance, usually made of bearing steel
2. Application scenarios
Widely used in metallurgy, wind power, mining machinery and other fields, such as conveyor driven rollers, printing press impression rollers, etc
Industrial case: Hydraulic steel bar straightening machine bearings (such as model 6201) used for construction machinery parts
