Suitable for high-speed, low-noise applications, including micro motors, instruments, laser engraving, dental drills, HDD motors, currency counters, fax machines, printers, and dental drills.
Product Structure
The R1810 ZZ bearing has an inner diameter of 7.938 mm, an outer diameter of 12.7 mm, and a width of 3.967 mm. It is made of stainless steel (such as AISI 440C) and features a deep groove ball design. Equipped with double shields (ZZ indicates double-sided metal shields), the bearing typically uses a nylon or stamped steel cage and is pre-lubricated with grease.
Main Performance Characteristics
It offers high-speed capability, low friction, corrosion resistance, and protection against dust and debris. The bearing operates smoothly with low noise and requires no additional lubrication maintenance. It is suitable for medium-to-high speeds and light-to-medium load environments. The stainless steel material provides good chemical resistance and temperature adaptability (operating temperature range approximately -30°C to +120°C).
Primary Application Scenarios
Commonly used in small DC motors, encoders, stepper motors, precision gearboxes, printer spindles, hard disk drives, household appliances (such as fans), laboratory instruments, and precision rotary platforms.
Technical Specifications & Requirements
Compliant with ISO 9001 and ABEC 1 (or higher) precision standards. The radial clearance is typically C0 group (normal grade). The maximum axial load should be determined based on actual operating conditions. During installation, avoid deformation caused by impact or excessive interference fits. The storage environment should be dry and rust-proof. For high-speed applications, it is recommended to control temperature rise and ensure appropriate axial preload.
