ABOUTROLMAN WORLD
50 Years of Experience with Industry
From a modest start 50 years ago, the Rolman World Group has evolved into the region’s dominant distributor for industrial spare parts & services. From its roots as a bearing distributor, the Group has consistently followed its principles of quality, customer service and technical know-how to become the Middle East & Africa’s foremost replacement parts & technical services provider. We remain our customers’ first choice across the region.
2015 saw the completion of our new Headquarters building in Dubai, and this investment has heralded the beginning of a new phase of growth and change within our Group. With a growing network of branches strategically located across the Middle East & Africa, we have set our sights on strengthening our market-leading position in four key business areas – Power Generation, Automotive, Industrial Wholesale and End User Direct.
TOOLS & MONITORING SERVICES
Timely maintenance and the correct parts will help you get the most from your machinery. However, it is vital to treat the components and your machinery correctly – when mounting and in operation, in order to get the maximum lifetime, and avoid unplanned, expensive downtime.
We supply the tools for heating, handling, fitting and removing the bearings and other components correctly. We can help you align your machinery correctly to avoid unnecessary stresses on components. We can work with you to monitor the condition of your machinery and components to understand how and when mechanical problems may cause or contribute to unplanned downtime.
COMPONENT FAILURE ANALYSIS
Our engineers are trained and experienced in establishing and understanding the root causes of component failure.
We can of course work with you to get the machinery moving again – but it is important to understand why a component has failed, in order to provide a lasting remedy. We work together with our manufacturers to understand the root cause of failure in your application, and provide a solution which drive improved performance, and allow your maintenance team to focus on other issues.
ON-SITE TECHNICAL SUPPORT
Whilst most distributors in the region are content to sell you their products, and leave you with your own problems, Rolman World stand ready to support our End User customers with extended technical services.
We have long experience in working side-by-side with maintenance departments to solve major problems – mounting giant-sized bearings with our specialist equipment; solving issues with gearboxes whose drive belts fail constantly; developing design solutions for screw conveyors and other machines which are a bottleneck for production processes; creating lubrication solutions in hard-to-reach or dangerous parts of your factory; and even working with you on machine overhauls during planned shutdowns. Replacing the part is not always the right solution.
SHARING BEST PRACTICE
Our extensive work with the region’s major End Users, and our engineers’ experience in each industry has given us invaluable insights into the most common maintenance issues, and the solutions which bring the best results.
We will work together with your Maintenance Departments and Production Engineers to identify the areas where our solutions bring added value, and where we believe we can help develop your efficiency and productivity.
TRAINING
We have invested heavily in our capabilities to train your engineers in the correct techniques.
We have the capacity to train up to 60 people at one time, utilising our manufacturers’ skills and experiences to bring the latest products and techniques to your teams. Our hands-on training facility at our Headquarters allows your staff to learn and practice best handling practices, eliminating some of the problems leading to shortened product lifetime, and therefore more downtime.
Partnership with the Region’s Major End Users
Nowadays, simply selling products is not enough. Manufacturers in every industry know that they need to continuously improve their productivity and reduce costs in order to stay ahead of fierce competition. Unplanned plant stoppages are expensive. Inefficient processes cost time and money.
As a serious partner to our End User customers, we have developed our capabilities to be able to discuss the requirements of every application, and to be able to offer the most effective solutions – be it a product, service, training or advice.
Our growing team of dedicated specialist MRO Sales Engineers, who have been brought together from across the region and are selected for their qualifications, skills and experience, are able to confidently work together with Maintenance & Production teams for a common goal – reduced unplanned downtime and increased production. Supported by our suppliers where appropriate, we will help you choose the right solution to suit your application and operational requirements.
STOCK SERVICES
For 50 years, Rolman World Group has been one of the Middle East & Africa region’s largest stockists of industrial spare parts. Our stock is second to none, and our experience has driven us to hold a comprehensive range of replacement bearings for all applications.
We will work with you to ensure availability of your requirements, and can supply it to your machine when you need it. We can put our stocks in your warehouse as part of a service agreement, releasing your resources, and leaving you to focus on your core business.

KEY PRODUCTS FOR INDUSTRIAL GEARS KEY PRODUCTS FOR ELECTRIC MOTORS
Industrial gears are used in many different sectors and often face dynamic operating conditions twinned with high shock loads in some cases. They are usually located between the drive on one side and the process technology on the other. In this case, industrial gears primarily serve to reduce input speeds and increase torques for the processes in question.
Electric motors and generators place completely different demands on bearings compared to gears. Knocks and fluctuating torques rarely occur. Different speeds are usually the key consideration when it comes to selecting bearings.

OIL, GAS & PETROCHEMICALINDUSTRY
STEEL & METALSINDUSTRY
KEY PRODUCTS FOR THE STEEL & METALS INDUSTRY KEY PRODUCTS FOR THE OIL & GAS AND PETROCHEMICAL INDUSTRY
The operational environment for our components is unique to steel making, comprising particle contamination, water and heat. In addition, components may have to cope with heavy or shock loads and vibration, operational speeds ranging from extremely slow to extremely high, coupled with rapid acceleration and deceleration. This makes for a demanding operational environment that is not found in other applications.
Minimising production stoppages and maximising productivity are crucial in the petrochemical industry. The machine components used in this sector – such as pumps, compressors, electric motors, blowers and ventilators – are particularly susceptible to change. These components contain bearings which have to work reliably and precisely, even in challenging conditions.
