अक्सर पूछे जाने वाले प्रश्न:
  • What is the difference between rubber seal and metal seal for LFR50 series bearings?
    Rubber seals provide excellent dustproof and waterproof performance for general environments, while metal seals are designed to resist high temperatures up to 200℃, making them suitable for harsh, high-heat working conditions.
  • When should I choose bearing steel (N) or PP material for these bearings?
    Choose bearing steel (N) for applications requiring high strength and heavy-load capacity. Opt for PP engineering plastic when you need corrosion resistance, low-noise operation, or are dealing with light-load scenarios.
  • Can LFR50 series bearings be customized with non-standard dimensions?
    Yes, the inner diameter, outer diameter, width, and groove size can all be customized to match specific guide rail configurations and equipment installation requirements.
  • In which industries are LFR50 series U groove track roller bearings commonly used?
    They are widely applied in automated production line guide systems, logistics conveying equipment, textile machinery guide rollers, printing machinery positioning mechanisms, engineering machinery auxiliary components, warehouse automation devices, and light-to-heavy load material handling systems.
