6300LLB Single Row Deep Groove Ball Bearing Double LLB Non-Contact Nitrile Rubber Seal 10x35x11mm High Speed Fan Micro Motor Equipment

The 6300LLB single row deep groove ball bearing adopts double-sided LLB non-contact nitrile rubber labyrinth seals, standard dimension 10×35×11mm. LLB non-contact design forms labyrinth gap without touching inner ring raceway, combining excellent dust resistance and ultra-low rotational torque, supporting radial load and slight bidirectional axial load. Pre-filled long-life lubricating grease inside, ideal for high-speed miniature fans, small electric motors, power tools and precision rotary equipment requiring quiet low-friction running.

• LLB non-contact labyrinth rubber seal: zero friction contact with inner ring, limit speed close to open bearing, much higher than contact 2RS/LLU seals
• Double labyrinth barrier effectively blocks fine dust, fiber and particulate impurities, prevents internal grease leakage
• 6300 series larger steel ball layout delivers higher radial load capacity than 60/62 series same bore bearings
• Precision superfinished raceway and steel balls realize ultra-low noise, stable vibration-free high-speed rotation
• Nitrile rubber seal maintains stable elasticity under wide temperature range, long service life without frequent maintenance
• Multiple optional variants: open 6300, dust-proof metal shield 6300ZZ, splash contact sealed 6300LLU/6300-2RS, C3 clearance
• Stainless steel anti-rust version can be customized for damp, light corrosion workshop environments
