Requirements: Core Bearing Requirements for the Power Tool Industry
1. Ultra-High Speed Operation Capability
Most power tools operate at speeds exceeding 15,000 to 40,000 rpm, therefore bearings need to possess excellent high-speed performance and low-friction characteristics.
2. Impact Resistance
Equipment such as electric hammers and impact drills are subjected to instantaneous impact loads for extended periods, placing higher demands on the strength and fatigue resistance of bearings.
3. High Sealing Protection
Construction sites are generally characterized by dust, moisture, and impurities. Bearings must possess excellent sealing performance to prevent contaminants from entering the interior.
4. Compact and Lightweight Design
Handheld power tools have stringent requirements for size and weight. Bearings need to achieve high load capacity and high efficiency within limited space.
