The Marine Single-row Crossed Roller Turntable Bearing is a compact and lightweight solution designed for high precision and small assembling clearance. With its crossed roller arrangement, it can effectively accommodate high axial, radial, and tilting moment loads. This slew bearing is ideal for applications in hoisting equipment and various engineering machinery, offering reliability and performance.

The Marine Single-row Crossed Roller Turntable Bearing is available in three tooth types: no gear, internal gear, and external gear. These options provide flexibility and compatibility for various marine applications. The no gear option offers a compact and lightweight design, suitable for applications where external gears are already present. The internal gear type facilitates easy integration with gear mechanisms inside the slew bearing, enabling smooth and efficient rotation. The external gear variant allows for direct power transmission and precise control of rotational movement. Choose the tooth type that best suits your specific requirements for optimal performance in marine environments.
In Single-row Crossed Roller Turntable Bearings, teeth are often incorporated on one of the rings to facilitate force transmission. The toothing is typically normalized or subjected to quenching and tempering processes. Depending on the specific application, the gears may be fully hardened or undergo single-tooth inductive hardening.
Single-tooth inductive hardening can be further categorized into two types: full tooth hardening and tooth foot (flanks and base) hardening. Full tooth hardening refers to the hardening of the entire tooth profile, ensuring enhanced durability and wear resistance. Tooth foot hardening, on the other hand, involves selectively hardening the tooth flanks and base, providing specific areas with increased hardness while maintaining flexibility in other regions.
The choice of tooth hardening method depends on the desired level of strength, load-bearing capacity, and wear resistance required for the particular application of the Single-row Crossed Roller Turntable Bearing.
