Product Detail

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 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.

Tooth Type Of Marine Single-row Crossed Roller Turntable Bearing

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.

Structure Of Single-row Crossed Roller Turntable Bearing

Structure of the Marine Single-row Crossed Roller Turntable Bearing:

  1. Inner Ring: Provides mounting structure and connects to the equipment.
  2. Outer Ring: Surrounds the inner ring, offering support and stability.
  3. Seal: Prevents contaminants from entering the bearing.
  4. Spacer: Maintains proper spacing between rollers.
  5. Ball/Roller: Enables smooth rotation and load accommodation.
