Self-aligning ball bearings are two major diameter roller, under a load, also can withstand any direction of the axial load. Have high radial load capacity, especially suitable for heavy work load or vibration, but unable to bear pure axial load. Tilting-pad bearing formed is spherical shape, its heart performance is good, can compensate the coaxial tolerance of error. 
Self-aligning roller bearings are two symmetrical type spherical roller, formed a share of the spherical roller, there are two and inner circle tilt Angle of an axis of bearings rolling, has a good heart, when the axial force performance when bending or install different heart bearings, still can use normally mind with bearing size series vary, generally permitted self-aligning Angle for 1-2.5 degrees, this type of bearing capacity, besides can bear radial load bearing can withstand the bidirectional effect of axial load, good resistance to impact, generally self-aligning roller bearings are allowed to work with low speed.

Selection and precautions of hydraulic cylinders for excavators
The hydraulic cylinder of an excavator is one of the important components, which converts hydraulic energy into mechanical energy,
Drive mechanical movement. When purchasing hydraulic cylinders for excavators, the following points should be noted:
1. Size and quality: The size and quality of the excavator hydraulic cylinder should match the model and specifications of the excavator to ensure its normal operation.
2. Pressure and flow rate: The pressure and flow rate of the excavator hydraulic cylinder should match the requirements of the hydraulic system,
To fully utilize the capabilities of the hydraulic system.
3. Sealing performance: The hydraulic cylinder of the excavator has good sealing performance to avoid hydraulic oil leakage or entering the mechanical interior.
4. Durability: The hydraulic cylinder of the excavator has good durability and can withstand long-term heavy load work.
5. Brand and Quality: Choose well-known excavator hydraulic cylinders to ensure their quality and after-sales service
