Description
Overview:
The Makita Ball Bearing 6307LLU HMJ1812 is a genuine, sealed deep-groove ball bearing designed for smooth, reliable rotation in power tools and site equipment. Made from hardened bearing steel with double rubber seals (LLU), it keeps grease in and contaminants out, helping to reduce friction and wear in high-speed, high-duty applications. Typical uses include electric motor shafts, gearboxes, spindles, and drive ends found in tools such as grinders, saws, and other construction or garden machinery. As an OEM component (Makita 211500-7), it is engineered for a precise fit and long service life. Standard 6307 dimensions: 35 mm bore (1.38 in), 80 mm outside diameter (3.15 in), and 21 mm width (0.83 in), making it a practical replacement for scheduled maintenance or repairs.
