According to Mr. Hemen Mehtalia, Managing Partner of Ramesh Bearing & Industrial Solutions, URB provides dependable bearings for crushers and screen crushers, such as spherical roller and cylindrical roller bearings. Their products undergo rigorous quality control processes and comply with international standards.

What types of crushers and screen crushers are commonly used in the industry, and which URB products are suitable for these applications?

Our products have proven reliability in following crusher types: Jaw crusher, Hammer mills, Roller crusher, Cone crusher, Horizontal shaft impact crusher.

The most requested products for this application are Spherical roller bearing, type MB-brass cage and Cylindrical roller bearing, with higher clearance than normal (C3). Depending on application, other types as tapered roller bearing or thrust ball bearings can be used.

How does URB ensure the quality and reliability of its bearings for use in crushers and screen crushers?

The steels used in the manufacture of bearings, martensitic hardening, are equivalent to those of international standards, vacuumed, with melting in electric furnaces, which ensure a high degree of purity.

Product design create products with high capacity which offer high durability and less energy consumption.

The Integrated Management System (Quality, Environment and Occupational Health and Safety) has the following certifications: ISO9001, IATF16949, ISO/TS 22163, ISO14001, ISO45001

What are the key factors to consider when selecting bearings for crushers and screen crushers, and how does URB's product range meet these requirements?

Bearing for crushers need to face vibration, high shocks and loads and high acceleration.

Spherical roller bearings type MB can face high loads and shocks, they have massive brass cage guided on inner ring and take misalignments.

For vibrating screens, URB has a special design “MAC4F80” – brass cage guided on outer ring that can limit inertia force of rollers and can assure a good tight of rings on shaft/housing.

What are some of the most common issues faced by crushers and screen crushers in terms of bearing performance, and how does URB address these issues?

To benefic of entire bearing life, users need to pay attention from beginning, from mounting procedures. Bearing failure can be caused by mounting, lubrication, contamination and fatigue.

Mounting need to be done with proper tools. Medium and large bearings require induction heater. Direct hits can lead to cracks.

In mounting phase, need to check quality of mounting surfaces (shaft, housing- dimensional and profile deviations). We need to assure that bearing is enough tight on shaft, to check clearance after mounting and not to misalign rings.

Crusher work in harsh environment. Another factors that shorter bearing life are: contamination with foreign particles and lubrication issues (improper quality, lubricant end of life).

What are some of the trends and innovations in the industry that are driving changes in the design and performance of bearings for crushers and screen crushers?

Permanently, the Research-Development staff implements new technologies, resulting from investments in equipment, machine-tools - installations, as well as modernizations, by developing the related documentation for the manufacture of bearing elements - on cold rolling machines, on CNC lathes, on the CNC grinding machine, on processing centers, on laser marking installations, on automatic packaging installations.

How important is maintenance and servicing for bearings used in crushers and screen crushers, and what are some best practices for keeping them running efficiently?

Maintenance is important for any application. As general recommendations:

•   Check oil regularly, making sure it is free of dirt and contaminants. Check daily, every 8 hours

•    Every 40 hours, check for leaks

•   Every month, inspect safety devices and perform an oil analysis.

•   At least once per year (or every 2,000 hours) change all oil.

Useful tools for bearing monitor: Electronic stethoscope, Sound meter, Infrared thermometer, Endoscope.

Accelerometer sensors accurately measure vibration, shock, acceleration, and motion for monitoring. Many common problems in machine, such as imbalance, play, misalignment can be evaluated by measuring vibration.

What are the environmental and sustainability considerations for the industry, and how are URB's bearings designed to address these concerns?

URB is certified ISO14001Environment Management System.

Our policy regarding the environment, health at work consists in ensuring a rigorous control of processes regarding environmental pollution, ensuring a favorable working environment and safe working conditions to prevent accidents and occupational illnesses.

To reduce utilities consumption, we have built Cogeneration Plant being able to obtain electric and thermal energy. Cogeneration can notably reduce carbon emissions and energy costs

How does URB use digitalization and automation to improve the performance and reliability of its bearings for crushers and screen crushers?

URB is using SAP software. SAP is based on ERP (Enterprise Resource Planning). ERP is business management software, it includes a suite of integrated applications, such as: Procurement, Customer Service, Production, Accounting, Sales.

ERP provides an integrated view of core business processes, often in real-time, using common databases maintained by a database management system. ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll.

Advantages: Sales forecasting, Order tracking, Matching purchase orders, Product trasability.

- SCADA- Heat treatment. One of the main characteristics of this system is that it acquires, stores and processes large amounts of data and makes the information it receives fundamental to the management of the heat treatment facilities.

-WMS. Warehouse management system. It optimizes warehouse operations, from reception to delivery.

-Product design department is using Creo Elements software for automatic design and Mesys-for bearing calculus and simulation.

-Turning and grinding workshops are equipped with CNC machines. Rollers are automatically sorted at outer diameter O.D and width.

What are the safety considerations for the use of bearings in crushers and screen crushers, and how does URB ensure its products meet the necessary standards and regulations?

Our products are design using advanced 3D software, such as Creo Elements, optimizing the internal construction, thus obtaining big value of load rating and safety factor S0 .

We guarantee safety operation of the bearings by having correct maintenance and on time.

What does URB do to prevent & stop fake / duplicate bearings reaching end consumer?

URB has Barcode & unique Hologram numbers which are available on their Bearings. This provides traceability against their dispatch & production reference.

Customer can visit URB website & click on contact tab - in that contact tab - click on fake URB tab to add photos of  bearing, hologram & barcode to get the INSPECTION REPORT for ''FAKE or GENUINE" directly from URB Romania to customers.
