Slewing Bearing Components

Slewing bearings, also known as slewing rings or turntable bearings, are large precision bearing components that simultaneously bear axial loads, radial loads, and tilting moments. They mainly consist of inner rings, outer rings, rolling elements, spacers, and seals. They are widely used in construction machinery, wind power equipment, port machinery, intelligent tower cranes, aviation radar, and other heavy-duty, low-speed slewing applications. As core transmission and load-bearing components of large equipment, their machining accuracy, surface quality, and stability directly determine the service life and working accuracy of the entire machine. Based on years of tool R&D and on-site process expertise, Ahno launches a total solution for slewing bearings. With dedicated tools for ID/OD turning, hole-making, and full-process adaptation, it provides reliable support for efficient, stable, and high-precision machining of slewing bearing components.

Case Details

Process:

1、OD rough turning (core first process)

2、Face and inner raceway rough turning

3、Semi-finish turning after heat treatment (OD, face, ID, raceway)

4、Finish turning (dimension finalization)

5、Raceway induction heat treatment (core precision process)

6、Drilling and thread machining

Ahno Loong Series Heavy-Duty Turning Inserts SNMM:

Rapidly removes forged blank surface scale, forging burrs, and allowance layers, preliminarily forms the OD datum, removes over 80% of stock, leaves uniform semi-finish allowance, and corrects blank roundness and face flatness to establish datum for subsequent machining.

Ahno Loong Series Heavy-Duty Turning Inserts CNMM:

Rough turns upper and lower mounting faces and ID contour, unifies workpiece thickness datum, ensures basic face parallelism, removes excess ID stock, and completes basic profile forming of the slewing bearing.

Ahno Loong Series Negative Turning Inserts WNMG:

Corrects minor deformation after heat treatment, further optimizes profile accuracy, uniformly leaves finish allowance, prepares for finish turning and grinding, and eliminates residual tool marks and dimensional deviations from roughing.

CBN inserts:

Finalize precision dimensions of OD, mounting face, ID, and shoulder steps, ensure geometric tolerances meet requirements, meet drawing accuracy requirements of IT6-IT7, and provide accurate datum for subsequent assembly and grinding.

穿山甲钻头、硬质合金钻头

在定位孔基础上钻螺纹底孔 / 安装通孔;选用穿山甲钻头，适配回转支承调质法兰材料，控制孔的直线度与孔径公差，是螺纹加工前置工序。

非标定制焊接铰刀

定制焊接成型铰刀精加工回转支承法兰定位孔，保障孔径与位置度，满足装配高精度定位要求。

非标定制焊接铰刀

孔口上下两面倒角，去除孔口锋利毛刺;消除装配应力集中，防止划伤螺栓、密封圈，保障回转支承装配贴合度，是容易忽略但影响整机可靠性的关键工序。

丝锥

对底孔进行攻丝加工，成型法兰连接螺纹;控制螺纹牙型完整度，防止崩牙、烂牙，保证回转支承螺栓预紧力均匀，满足重载工况下连接可靠性。
