Medium sized deep groove ball bearings are the most common type of ball bearings, they have the following features:
• Radial load and axial load can be taken at the same time
• Low torque hence low power loss
• Higher speed and lower noise possibility than any other types of rolling bearings
• A very limited degree of misalignment to be taken
MTWB provides customized medium sized deep groove ball bearing solutions for OEM manufacturers, industrial equipment suppliers and engineering applications that require reliable radial and axial load performance. Our medium sized DGBB bearings can be customized according to application requirements, including bearing dimensions, internal clearance, sealing configuration, cage design, precision class, lubrication and operating conditions.
Depending on the application, MTWB can support standard and customized deep groove ball bearing solutions for electric motors, gearboxes, pumps, conveyors, agricultural machinery and other industrial equipment. Customers can provide bearing drawings, dimensional requirements or application parameters for technical evaluation and customized bearing development.
With flexible OEM and ODM capabilities, MTWB focuses on providing cost-effective deep groove ball bearing solutions with consistent quality, stable performance and application-specific specifications. Our engineering team can help customers select or customize the appropriate bearing design based on load, rotational speed, temperature, contamination level, lubrication requirements and expected service life.
Apart from standardized bearing fully compatible international brands, MTWB engineering team has vast experience in designing or customizing and making of deep groove ball bearings. Before a manufacturing drawing is finalized, our engineering team needs to understand deeply OE customer’s application and work closely with them to determine a unique bearing solution, such as:
Thermal stability is the limiting factor to the maximum speed of a bearing, not the mechanical speed limit. Hence a design of thermal stability at higher temperature will allow a higher bearing speed or speed capability. Usually sealing is the determining factor of the thermal stability. MTWB engineering team is able to design the thermal stability to run up to 450℃, compared to only 120℃ of a standard bearing. We can also make the best-performance bearing down to -200℃, or in accordance with customer’s specification of corrosion or wear resistance using stainless steel or alloys.
The bearing clearance refers to the spacing between a bearing’s rolling element and the inner and outer ring. The total spacing is referred as radial clearance or axial clearance depending on the direction of movement. The operating clearance (also called working clearance) has direct effect on bearing fatigue, temperature increase, noise and vibration hence experience counts when selected.
The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls.By increasing the diameter and number of steel balls and the optimization plan of the internal raceway curvature structure of both inner and outer rings, our engineering team can get a longer bearing life compared to a standard bearing.

A medium sized deep groove ball bearing (DGBB) is a rolling bearing designed to support radial loads and moderate axial loads in both directions. Compared with miniature and small bearings, medium sized DGBB bearings are commonly used in applications requiring higher load capacity, reliable rotational performance and long service life. They are widely used in electric motors, gearboxes, pumps, industrial machinery and other mechanical equipment.

Yes. MTWB can support OEM and ODM deep groove ball bearing projects based on customer drawings, dimensional specifications and application requirements. The engineering team can review the drawing and technical requirements, evaluate the bearing structure and manufacturing feasibility, and develop a suitable production solution. This drawing-based customization service is suitable for OEM customers who require application-specific medium sized DGBB bearings.
Medium sized deep groove ball bearings are widely used across industrial and commercial equipment applications. Typical industries include electric motors, automotive components, industrial gearboxes, pumps, compressors, conveyors, agricultural machinery, material handling equipment, power tools and general mechanical equipment. The appropriate bearing design depends on factors such as load, speed, operating temperature, contamination, lubrication and expected service life.
MTWB can provide different internal clearance and sealing configurations according to application requirements. Common internal clearance options include standard clearance and increased clearances such as C3, while sealing configurations may include open bearings, metal shields and rubber seals such as ZZ and 2RS. Customized clearance, sealing and lubrication solutions can also be evaluated for specific operating conditions, including high-speed, high-temperature, dusty or moisture-prone applications.
