Brand: MTWB (Mighty Way Industrial Limited)
Product Series: Heavy Duty Truck Separable Bearing
The MTWB Separable Bearing for Heavy Duty Truck is a precision-engineered core component designed specifically for clutch systems in heavy-duty commercial vehicles. Developed to address the demanding requirements of high-load operation, frequent engagement cycles, and harsh working environments, this bearing provides stable performance, reduced maintenance requirements, and a cost-effective alternative to international brand bearing solutions.
As a separable bearing, the inner ring assembly (cone with rollers and cage) can be mounted independently from the outer ring (cup), enabling easier installation, removal, and precision clearance adjustment. This design is particularly advantageous for heavy-duty truck applications where maintenance efficiency and operational reliability are paramount.
MTWB leverages over 18 years of bearing manufacturing experience and serves 100+ OEM customers worldwide, offering customized solutions for automotive and heavy equipment manufacturers.
The bearing body features high-precision spherical geometry, ensuring low friction and stable high-speed operation essential for clutch systems in heavy-duty trucks.
Unlike conventional single-layer sealing mechanisms that experience lubricant leakage over time, MTWB's dual-layer sealing structure significantly improves dustproof, waterproof, and oil leakage resistance:
Double-sided sealing rings with an additional F rubber sheet sealing layer
Patent-certified design that greatly enhances sealing performance
Extended service life under contaminated operating conditions
The bearing uses Krupp high-performance synthetic grease (B L P 72-12), specifically formulated for heavy-duty, high-temperature, and high-speed rolling bearing applications.
The separable configuration allows independent mounting of the cone and cup assemblies, simplifying installation, dismounting, and inspection procedures.
Engineered for clutch systems with limited space, the bearing's compact design ensures compatibility with modern heavy-duty truck configurations.

A separable bearing is a bearing where the inner ring assembly (cone, rollers, and cage) can be mounted independently from the outer ring (cup). In heavy-duty trucks, it serves as the core component of the clutch system, enabling smooth disengagement and engagement of the drivetrain.
Separable bearings simplify installation and maintenance, allow precision clearance adjustment, and reduce downtime during servicing. This is particularly valuable for heavy-duty truck applications where maintenance efficiency directly impacts operational costs.
MTWB's patent-certified dual-sealing structure prevents lubricant leakage, blocks dust and moisture ingress, and extends bearing service life in harsh operating environments – common challenges in heavy-duty truck applications.
Yes. MTWB offers custom dimensions, sealing systems, lubrication options, and OEM manufacturing services according to customer requirements, supporting both prototype development and mass production.
MTWB bearings undergo rigorous bench simulation testing including 2 million life cycles at 150°C operating temperatures, validating sealing integrity, rotational resistance, and overall durability under extreme conditions.
