The SE series slewing drives demonstrate numerous outstanding advantages in the industrial field, providing strong support for the efficient operation of various mechanical equipment.
Thanks to its unique structural design, the flanged slewing bearing integrates the slewing and load – bearing functions within a limited space. It is applied in many fields such as construction machinery, energy, special – purpose vehicles, port and ship, industrial automation, and robotics. It has the advantages of easy installation, precise positioning, strong load – bearing capacity, smooth operation, and good sealing performance. Moreover, it features high manufacturing precision and strong reliability.
The precision grades of bearings are primarily classified based on dimensional accuracy and rotational accuracy.
The importance of bearing installation lies in its direct relation to the operating accuracy, stability, reliability, and service life of mechanical equipment. Improper installation may lead to frequent equipment failures and even premature scrapping.
Spur gear drive (straight gears) are one of the most common and widely used types of gears in mechanical transmission. Their teeth are parallel to the axis, and they have the characteristics of a simple structure, easy manufacturing, low cost, and high transmission efficiency (up to 98% – 99%). Spur gears are mainly used for […]
Slew drive is a kind of slewing drive device, which has the characteristics of high load capacity, high precision, compact design, good sealing performance, high integration degree, convenient installation and maintenance, large transmission ratio, and high safety. It can play an important role in a variety of different industrial fields and equipment, achieving precise rotary motion and reliable load support.
The roller bearing uses rollers as rolling elements, has a strong load-bearing capacity, and is suitable for situations where a large load needs to be borne. In contrast, the ball bearing uses balls as rolling elements, has low friction resistance, can withstand combined loads, and is suitable for equipment with high requirements for rotational accuracy and flexibility.
It features a two-row ball structure and is widely used in mechanical equipment requiring high-precision rotation and heavy-load capacity. A double row ball slew bearing is a large rotational bearing designed to withstand combined axial loads, radial loads, and overturning moments
Slewing bearings are core components of equipment, and it is of utmost importance to maintain them. Maintenance can extend their service life, reduce the failure rate of the equipment, and avoid economic losses caused by downtime due to failures. What is the feature of slew bearings? Bearings are crucial components in mechanical transmission. They reduce […]
