Slewing Bearing Full-time Job2022-05-19 12:45 Engineering Sar-e Pul 31 views
Slewing Bearings, or turntable bearings, are ball or roller style bearings composed of two concentric rings either of which may include a gear. This type of bearing enhances load support and power transmission in all directions, and is typically employed to support heavy loads for slow applications and large equipment such as earth excavators and construction cranes. The unique power and versatility of slewing ring bearings has made them increasingly valuable in a wide array of industries, including construction, industrial, robotics, machine tooling, and medical applications.
To "slew" means to turn without change of place. A slewing bearing or slew[ing] ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads.
Slewing rings are known worldwide as premium products in the field of rolling bearing technology. These machine elements have proven themselves many times over; they have high load-carrying capacity, a versatile range of applications and are highly cost-effective. Due to their design, a single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing. This reduces - in some cases considerably - the costs and work required in the design of the adjacent construction and the fitting of bearings.
Slewing rings are sealed on both sides, lubricated with a high-quality grease, can be relubricated via lubrication nipples and are particularly easy to fit. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth.
How do you test a slewing bearing?
One of the most basic indicators of slewing ring bearing problems is the condition of the lubricant. If metal particles or flakes are apparent, some form of wear is taking place. Grinding, popping, or clicking noises from the bearing typically mean there is inadequate lubrication and/or excessive wear in the raceway.
