• ✰[High Material]: Deep groove bearings made of High-carbon steel. These bearings effectively absorb vibrations and impacts while reducing noise. The outer groove remains unmachined with a dark finish. Rotational speed is less than 1000rpm. The inner bore is machined to a brighter, more uniform finish with an error tolerance of ±0.05mm. Suitable for low-speed, low-demand environments such as: low-speed transmission equipment, mechanical hardware devices, casters, etc.
• ✰[Pre-lubricated Design]: Internal ball bearing retains lubricant. Ensures smooth operation and reduces frequent maintenance needs. Facilitates daily upkeep. Lubricant can be replenished as needed to extend service life. External metal structure effectively blocks foreign object intrusion, significantly enhancing bearing operational stability and reliability. [Note: Lubricant is not included in this kit.]
• ✰[Easy installation]: Moisture or perspiration may cause bearing corrosion. Avoid prolonged exposure to humid environments during use. Standardized dimensions ensure easy installation, saving time and effort during assembly or replacement.
• ✰[Wide Application]: Ideal for low-load applications such as low-speed transmission equipment, casters, and toy vehicles. Suitable for diverse devices including skateboards, inline skates, scooters, and remote-controlled cars to meet varied usage needs.
