What is Slewing Bearing?

A slewing bearing or slew or slewing ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis (yaw) windmill. In other orientations (e.g., a horizontal axis of rotation) they are used in materials handling grapples, forklift attachments, welding turnover jigs and so on.

Features of Slewing Bearing

Depending on the design and structures, slewing bearings have the following features:

High load carrying capacity

High stiffness for rigid bearing application

Low friction

Long service life

Surface protection and corrosion resistance

Integration of additional features, including:

Driving mechanism

Control devices

Lubrication systems

Monitoring systems

Sealing cassettes

Applications of Slewing Bearing

Depending on your application needs, these bearings are available in various designs and used in a wide array of industries.

The power and versatility of these bearings have made them increasingly valuable in these industries:

Construction - supports heavy loads for slow applications and large equipment (as in construction cranes)

Industrial - Mining, Steel, Agriculture, Oil & Gas

Robotics equipment

Machine tools

Medical applications

Aerospace & Defense

Slewing rings are designed to facilitate highly accurate support and mobility. They may have very intricate bolt hole patterns in both the inner and outer rings for easy mounting.

Compared to other rolling-element bearings, slewing bearings are relatively thin sections. They require that the structure to which they are bolted is hard enough so that under load, predefined distortion limits are not exceeded.

How to find a trustworthy Slewing Bearing supplier?

When it comes to choosing slewing bearing suppliers, procurement departments rely on a number of qualitative, quantitative, subjective and objective criteria.

1. Supplier cost

Probably the most obvious – but equally important – factor to take into consideration when looking for new suppliers, is cost.

Of course, you’ll have a figure in mind as you’ll know which products you’re looking for, and how much you’re willing to pay. Even so, prices between suppliers can vary, so it’s important to shop around and see who offers the best deal. For instance, some suppliers may offer discounts on bulk-buying; or others may offset higher costs with better quality products.

You should weigh up all of the options when it comes to costs, before deciding which supplier is best in that respect.

2. Quality

There’s often a correlation between cost and quality: the more expensive the product, the better the quality. Regardless of price, there is still a predetermined, agreed level of quality, and you want to be sure that your expectations are met.

After all, the last thing you want to do is market your products as high-end, when your supplier sends you something completely different.

Quality doesn’t just refer to the physical product itself, but its associated aspects too. Are the products packaged adequately, protecting them in transit? Are they labelled correctly? Speak with potential suppliers to ensure that you’re fully aware of what they will offer you – you don’t want to sign a contract and then be disappointed.

3. Reliability and previous experience

It’s important to remember that when choosing a supplier, you’re essentially entering into a long-term relationship with them. It’s similar to hiring a new recruit – you’ll want to see references.

Don’t be afraid to ask for them: it makes sense that you would want to hear from businesses who have worked with specific suppliers in the past, as they can give you an honest account of what the partnership was like, and list any good or bad points.

If you’re deciding between two suppliers, references can make all the difference when deciding who to choose.

Your chosen supplier will directly reflect upon your business. If they send over a batch of products two weeks late, the customer who ordered that product will blame you, not your supplier.

4. Shared culture

Expectations are only met when they are clear on both sides. A good supplier relationship is built on shared cultural goals and attitudes. Speak with suppliers directly to find out how they like to work with other businesses. If you want constant communication but they prefer to just “get on with it”, then realistically, that’s not going to work.

When speaking with suppliers, whilst you’ll have questions to ask them; it’s likely they’ll have equally as many questions for you. Use this time to gauge whether your culture and expectations are similar, as you should get a good idea of whether or not the relationship will work.

5. Location

When choosing a supplier, location is a big factor to consider. If you’re a local business that has built your brand on expertise in your area, then you’ll want to focus on finding a supplier who is located nearby, and shares your values.
