Power Tool Bearings
-- Steady & Reliable Manufacturer --
Brief Description
Compact, high-speed ball bearings engineered to endure rapid acceleration, high rotational speeds, and the shock loads typical of hand-held electric power tools.
Introduction
Bearings in power tools, such as drills, angle grinders, and circular saws, operate at speeds far exceeding typical industrial machinery, sometimes reaching 30,000 RPM or more. This requires P5 or P4 precision to maintain stability and prevent overheating. Furthermore, impact tools demand bearings that can handle sudden, intense loads. Our power tool bearings are constructed with high-quality steel and high-speed synthetic grease to deliver maximum performance, minimal runout, and the longevity required by both professional and DIY users.
