For ball and roller bearing manufacturers, the future looks relatively bright. According to Freedonia Group, global demand for bearings is projected to rise 7.3 percent annually through 2018, with ball and roller bearings driving the growth..
However, even with optimistic forecasts, industry leaders can’t afford to rest on their laurels. Market opportunity only intensifies competition, and ball and bearing manufactures are already fighting against imports from lower-cost countries. Staying profitable in a global market requires manufacturers to constantly seek new ways to both differentiate themselves and minimize costs. This means continuous improvement and optimization are critical.
The Workflow Challenge
To remain competitive, today’s industrial manufacturers need to face their greatest operational challenges head on, starting with improving workflow and eliminating bottlenecks. As stated in the latest white paper from the LENOX Institute of Technology, this is one of the top five challenges ball and roller bearing manufacturers face. Workflow bottlenecks can negatively impact productivity, customer delivery, and ultimately, the bottom line.
Identifying and eliminating bottlenecks is a difficult, but important task for any metal-cutting company striving to be successful. For example, in an article from manufacturing.net, Curt Schmidgall, value stream manager at Winegard, describes how the antennae manufacturer struggled to meet market demand. A lean manufacturing exercise revealed the issue: Product testing at the end of Winegard’s manufacturing process was creating a huge bottleneck. By changing when the testing occurred (during the assembly process versus after the product is built), the company more than doubled its output and was able to meet market demand.
Like Winegard, many companies are using lean manufacturing strategies to reduce bottlenecks and improve workflow. This includes applying the well-known Theory of Constraints, as well as a host of other lean tools. However, don’t get bogged down with the terminology; continuous improvement doesn’t have to be complex to have an impact. While you may not have the extra hours or resources to implement an aggressive lean program, there are some basic strategies managers can use to improve workflow.
In Reliable Plant’s article, “6 Ways to Get Lean in 2015,” three of the six strategies listed are geared specifically toward improving your operation’s workflow. These tactics are good examples of how “lean” can be simple, but effective:
- Reduce motion. Follow your employees and note where they go during the production process. Reduce unnecessary movement and focus on making every other movement efficient. This will help save time and boost production.
- Eliminate wait times. Idle equipment and means wasted time and energy. Walk the shop floor and modify processes to eliminate time spent waiting on order information, material, quality checks, or repairs.
- Assess the floor. Maximize the shop floor for movement and organization. Make work areas, forklift lanes, and storage areas easily identifiable and accessible.
In the end, the pressure to meet customer deadlines can easily take priority in any high-volume manufacturing operation, especially as demand increases. However, manufacturing leaders know that constantly improving their processes and attacking challenges like workflow can make all the difference. By implementing even a few simple lean strategies, ball and roller bearing manufacturers can identify and eliminate bottlenecks, improve productivity, and increase profitability.

The key to customer satisfaction has always been finding a balance between fast turnaround and high quality. Growing demand has made this even more of a challenge for many of today’s ball and roller bearing manufacturers. With the economy poised for recovery thanks to stronger demand from the transportation and industrial manufacturing industries, industry analysts are anticipating increased demand for ball bearings. According to a report from Freedonia Group, global demand for bearings is projected to rise 7.3 percent annually through 2018, with ball and roller bearings registering the fastest gains.
This increase in demand is certainly good news for manufacturers, but it also means that companies need to make sure they remain focused on quality. Speed and agility will always be key attributes of any leading high-production operation, but they cannot come at the expense of accuracy.
To help ball and roller bearing manufacturers ensure quality in their metal-cutting operations, below are a few highlights from the paper, The Top Five Operating Challenges Ball and Roller Bearing Manufacturers Face in Industrial Metal Cutting, written by the LENOX Institute of Technology:
- Think of the long-term cost impact of short-term production gains. Ball and roller bearing production requires high-speed, precision cutting, and pushing machinery too hard can directly impact the quality of a cut and long-term costs. In circular sawing, for example, if an operator increases the speed of the saw to get more cuts per minute without considering the feed setting or the demands of the material, the end result will be premature blade failure. These actions are costly in terms of process flow and equipment. When blades cost several hundred dollars, going through twice as many blades just to get 50 more cuts just isn’t cost effective. In addition, shorter blade life creates more unplanned downtime for blade changes.
- Many industry leaders are also finding that becoming ISO 9001 certified can help them maintain quality standards. The ISO standard is based on a number of quality management principles, including a strong customer focus, the motivation and implication of top management, and continuous improvement. The basic goal of the standard is to help companies provide customers with consistent, good quality products and services, which, in turn, often brings business benefits like improved financial performance. It most cases, it is used to strengthen an existing quality program by making it a formal, documented procedure.
- Close supplier relationships can also help ball and roller bearing manufacturers improve quality. Many supply chain partners are willing to lend their expertise to help optimize processes and ensure that manufacturers are getting the best possible results out of their equipment and industrial metal-cutting tools. By utilizing value-added services from trusted suppliers and making them more of a partner, managers have another means of improving both quality and productivity. In fact, this is one of the eight key principles on which the quality management system standards of the ISO 9000 series are based.
