Tandem thrust cylindrical roller bearings consist of several single-stage thrust cylindrical roller bearings, outer spacers, inner spacers, and a shaft. They feature a simple and compact structure, save installation space, are easy to install and debug, provide uniform load distribution, are wear-resistant, have low vibration and noise, long service life, and high axial load capacity. They have been applied in most twin-screw extruder gearboxes and have become a core component of twin-screw extruders. Our company can provide two-row, three-row, four-row, five-row, six-row, seven-row, and eight-row tandem thrust cylindrical roller bearings, including shaft-type and sleeve-type variants, as well as custom processing and design according to customer size requirements. Customers can select the required bearing model based on screw center distance, space constraints, and load capacity.

2. Shaft-Type Tandem Thrust Cylindrical Roller Bearings

Mentor Bearings' shaft-type tandem thrust cylindrical roller bearings combine the standard tandem thrust cylindrical roller bearings with a shaft. They are characterized by design flexibility, the ability to adapt to different types of installation shafts, and ease of installation and disassembly. This design allows the bearing to adapt to various application scenarios, enhancing convenience of use. These features make shaft-type tandem thrust cylindrical roller bearings excel in situations requiring frequent replacement or adjustment of installation shafts. Whether for maintenance of mechanical equipment or installation of new equipment, Mentor Bearings provides efficient and convenient operational experiences.

3. Sleeve-Type Tandem Thrust Cylindrical Roller Bearings

Mentor Bearings' sleeve-type tandem thrust cylindrical roller bearings consist of several thrust cylindrical roller bearings, outer spacers, inner spacers, and a sleeve. They are typically composed of Grade 6 or Grade 8 thrust cylindrical roller bearings connected in series, with an overall or half sleeve added externally. Sleeve-type tandem thrust cylindrical roller bearings feature radial positioning, and the sleeve protects bearing components. They come with preload, eliminating the need for adjustment during use. These bearings have a small radial size, high axial load capacity, excellent load-bearing performance, higher assembly accuracy, and are convenient for transportation, storage, installation, use, and maintenance.
