  • 01. Slewing Drive

    Slewing drive is a kind of all-round slewing decelerating transmission mechanism integrated with driving power source. It uses slewing ring as driving follower and mechanism attachment. By attaching the driving part, driving source and cover on one of the inner and outer rings of slewing ring, the other ring is regarded as both the driving follower and the connecting base of the driven working parts. In this way, slewing ring is used It is the feature of all-round rotation connecting piece. It is a general-purpose decelerating transmission mechanism which integrates the functions of rotation, deceleration and driving, but also has simple structure and convenient manufacture and maintenance.

  • 02. Slewing Bearing

    Slewing bearing is also called rotary bearing. Some people also call it: slewing bearing and slewing bearing. English names are: slewing bearing, slewing ring bearing, turntable bearing and slewing ring. The slewing bearing is widely used in the real industry, which is called "the joint of the machine". It is an important transmission part of the machine which needs to make relative rotary motion between two objects and bear axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing ring has been widely used in ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

    Jingwei engineering

    Jingwei engineering Jingwei engineers have engineering experience and expertise—on average, each has 20 years experience in bearing engineering. It's no wonder Jingwei engineers have a proven track record of solving the world's most demanding bearing challenges. Typical bearing suppliers provide standard solutions and average performance while requiring a high minimum order quantity. The Jingwei process is different. Our engineers are accessible and flexible, applying their expertise whether it's a catalog bearing or custom, and whether the order is for one or thousands. Jingwei engineers specialize in a given industry (e.g., aerospace, medical, heavy machinery) and, unlike at other suppliers, follow a project through product design, manufacturing, and testing. This provides an in-depth understanding of product and material performance and selection. When customers require stronger, lighter, smaller, faster, and/or quieter bearings and assemblies, they know they can count on Jingwei engineers for the ideal application-specific solution. Jingwei's engineering expertise is apparent in all of our offerings. Thin section and slewing ring bearing solutions meet the highest quality standards and are available with a wide variety of materials, sizes, separator types, and more. Kaydon's research, development, and testing labs evaluate and verify product performance with exhaustive testing. Our free Reali-Design® engineering aid software computes essential life and load analyses (and much more), significantly saving you time. To find out how Kaydon can help solve your bearing challenges, contact us at 800.514.3066 or submit a data specification sheet for custom bearings or custom slewing ring bearings.

    Jingwei's engineering expertise and experience extends to the Jingwei research, development, and testing labs. Jingwei engineers use advanced analytical tools and calculations to understand, test, and recommend the best possible bearing solution for each customer and application. Bearings, gears, bolts, and assemblies are evaluated on several factors that can impact performance, including strength and integrity, load and speed, torque and vibration, metallurgic and dimensional characteristics, and environmental impacts. Extensive testing is conducted to verify performance claims, ensure that custom specifications are met, and analyze failure and wear.

    Jingwei environmental health and safety performance report

    At Jingwei, we continue to take proactive steps to evaluate and reduce the impact of all our products on the environment. Using independent third-party reviews of our operations, we've developed key environmental performance metrics in response to our customers' needs. Our annual Environmental Health & Safety Performance Report helps our customers pursue environmental improvements in their product and supply chains. We're proud of the environmental improvements we've made, including: Substantially reducing water usage, even as production has trended up. Decreasing hazardous waste generation rates, even as production has increased. The use of solvents known or suspected to be carcinogenic is prohibited in our facilities. Increasing the amount of coolant we recycle and improving our procedures for reducing waste and capturing materials for beneficial reuse. Recovering and recycling as much scrap metal as possible (recently, we recycled almost 3 million pounds).
