LTZC robotic precision slewing bearings have passed inspection.

LTZC precision robot slewing bearing has been pass  inspection

Recently, LTZC's independently developed and manufactured precision slewing bearings for robots successfully passed a series of rigorous performance tests.  All key indicators met international standards, fully demonstrating LTZC's strength in high-end robot bearing research and development and manufacturing. This further consolidates its competitiveness as a professional bearing supplier in the global market and represents another significant achievement in the import substitution of core components for domestic robots.

The robot bearing tests focused on the core performance of the precision slewing bearings, covering key dimensions such as rotational accuracy, load capacity, wear resistance, low-noise operation, and stability.  The tests strictly followed international robot bearing testing standards and national and industry standards such as GB/T307 and JB/2300.  The entire process was supervised by a professional testing team. The precision slewing bearing submitted by LTZC for testing maintained a stable P4-level high rotational accuracy. After thousands of hours of continuous operation under high-speed and heavy-load conditions, there was no significant wear, deformation, or accuracy degradation. Noise control was superior to industry standards, fully meeting the stringent requirements of high-end equipment such as industrial robots and collaborative robots for core transmission components. It can be widely adapted to the needs of robots in various fields, including construction machinery, medical equipment, and precision machine tools.

High Demands on Precision Slewing Bearings in Robotic Applications

Compared to engineering machinery or port equipment, robots place even higher demands on the performance and precision of slewing bearings:

High-precision positioning: Requires bearings with extremely low rotational accuracy errors and stable operating trajectories.

High rigidity and low clearance: Maintaining structural rigidity and reducing backlash under complex motion trajectories.

Low friction and low noise: Meeting the needs of continuous operation and precise work in robots.

Long lifespan and high reliability: Adapting to high-frequency start-stop and multi-axis linkage working conditions.

This presents a systematic challenge to bearing design, material selection, processing accuracy, and assembly and testing capabilities.

Why choose LTZC robot  precision bearing？

As a professional bearing supplier with over 30 years of experience in the bearing manufacturing field, LTZC has focused on the research and development and manufacturing of large, extra-large, and precision bearings since its establishment in 1992.  Leveraging its comprehensive production system, advanced processing equipment, and strong technical capabilities, LTZC has gradually built a manufacturing capacity covering the entire lifecycle of robot bearings, becoming one of the benchmark enterprises in the domestic precision slewing bearing field. The robot precision slewing bearing that passed the tests this time is a concentrated embodiment of LTZC's technological accumulation and manufacturing strength, backed by the company's rigorous control and continuous innovation in all aspects of materials, processing, and quality control.

In terms of core manufacturing capabilities, LTZC has established an industry-leading precision processing production line, equipped with a series of high-end processing equipment including a 6-meter CNC vertical lathe, a 1.75-meter vertical grinding machining center MX-1800, a 2.5-meter floor-type grinding machine, and a CNC raceway hardening machine. This enables automated and refined production throughout the entire process, from raw material processing and raceway grinding to heat treatment and finished product assembly. Processing accuracy can stably reach P0-P4 standards, and the product outer diameter covers Φ300mm-Φ6000mm, accurately matching the needs of different specifications of robots. 

Addressing the high demands on material performance for robot precision slewing bearings, LTZC optimizes its material selection process, using high-purity alloy materials. Through advanced heat treatment technologies such as controlled atmosphere nitriding and laser surface treatment, the hardness, wear resistance, and fatigue resistance of the bearing materials are effectively improved, increasing the rolling contact fatigue life of the bearings by more than 45% compared to traditional processes, completely solving the industry pain points of easy wear and short lifespan of high-end robot bearings under heavy load and high-speed conditions.
