More Than a Supplier — Your Reliable Bearing Partner.
The BL-D Series Angled Ball Joint is designed with a compact angled structure, metric threaded connection, and rubber sealing protection to provide smooth movement, reliable positioning, and long service life. This Metric Ball Joint is engineered for applications requiring flexible angular movement and secure mechanical connections. The threaded design allows easy installation, while the rubber seal prevents dust, moisture, and contaminants from entering the internal joint structure.
The BL..D Series is an angular die-cast ball joint bearing. The ball housing is made of zinc-based alloy through precision die-casting, equipped with left-hand or right-hand double threads (threads at both ends) and built-in rubber seals. Specifically designed for angular double-thread connection, light-medium load scenarios in equipment, the angular double-thread structure enables direct angular butt joint of two equipment linkages without additional nuts or adapters, ensuring extremely high assembly efficiency. The ball operates flexibly, and the rubber seal protects against dust and moisture, serving as a convenient solution for angular double-end connections in general machinery and light industrial equipment.
Core Advantages of BL-D Series Angled Ball Joint
Reliable Ball Joint Linkage Performance
