Guangde Boran Technology Co., Ltd manufactures self-lubricating bearings and bronze bushings, offering one-stop production from casting to finished parts with in-house testing and strong R&D.
Guangde Boran Technology Co., Ltd focuses on the R&D and manufacture of self-lubricating bearings, oil-free bushings, and bronze bushings, providing a one-stop production route from raw material casting through precision finishing. The company develops proprietary formulations for JDB self-lubricating bearings and supports ongoing new product development with domestic and international partners.
Its product range covers multiple copper alloy materials, including high brass, tin bronze, aluminum bronze, phosphor bronze, manganese silicon bronze, and lead copper, and it can manufacture to customer requirements. To ensure stable quality and lead times, the factory operates multiple sheet sintering lines, professional finished-bearing production equipment, and a complete set of inspection and testing equipment, with key parameters and tolerances checked in its own laboratory.
Boran’s bearings and bushings serve broad industrial applications, including automotive components, metallurgical and mining machinery, marine equipment, energy and renewable energy equipment, construction and engineering machinery, hydraulic systems, and plastics and mould industries.

An integrated manufacturer covering the full process from raw material casting to finished bearing production, supporting custom requirements and consistent delivery.
Operates multiple sheet sintering lines and professional finished-bearing production equipment to support stable product performance and reliable lead times, including customized items.
Maintains a complete set of testing equipment. Sheet parameters, performance indicators, and finished-part tolerances are inspected with in-house laboratory equipment to ensure products meet release standards before shipment.
Used across passenger and commercial vehicle applications, including belt tensioners, starters, alternators, pulleys and dampers, oil and water pumps, common-rail injection pumps, air-conditioning compressors, steering knuckles, rocker arms, differentials, and balance shafts.
Applied in engineering machinery such as guide wheels, track chain wheels, and support rollers, as well as equipment used in ports, mines, and construction sites.
Committed to long-term development of JDB self-lubricating bearing technology, combining in-house formulation work with continuous new product development in cooperation with customers and partners.
