LTZC Slewing Bearing Manufacturer Celebrates the Dragon Boat Festival

To celebrate the Dragon Boat Festival,LTZC Bearingshosted a zongzi (sticky rice dumpling) wrapping event in the company cafeteria. Representatives from various departments gathered to wrap the dumplings—filled with glutinous rice and red dates—amidst an atmosphere of constant laughter and cheer. A prominent banner reading "Party Building Leads the Way to Corporate Prosperity; Rich Zongzi Aromas Celebrate the Dragon Boat Festival" highlighted the spirit of leadership through Party principles and team unity. At noon, everyone enjoyed the fruits of their labor, savoring the fragrant dumplings; in the afternoon, the company distributed holiday gifts to all employees, bringing smiles to everyone's faces. This event not only promoted traditional culture but also showcased the company's "people-oriented" philosophy. Through collaboration and sharing, employees felt a stronger sense of belonging and heightened enthusiasm for their work, injecting a heartwarming momentum into the company's high-quality development.

Following the Dragon Boat Festival team-building event, key workshop personnel and sales staff proactively shared their thoughts, unanimously expressing that the company’s thoughtful, people-oriented care fostered a stronger sense of belonging and a willingness to fully dedicate themselves to the R&D, production, and overseas delivery of slewing bearings. This heartfelt team cohesion has directly translated into momentum for the company's high-quality growth: for the 2025–2026 period, LTZC maintained a stable on-time delivery rate of 99.6% for overseas orders, with a customer complaint rate of less than 0.3%—figures far superior to industry averages. Furthermore, several models of photovoltaic tracking slewing bearings and high-tonnage slewing bearings for construction machinery have secured long-term repeat orders from clients across Europe, the Americas, Southeast Asia, and Central Asia.

I. LTZC Slewing Bearing Manufacturing Capabilities
