Miniature & Instrument Bearing Supplier | Alpine Bearing

Compact sealed bearings for laboratory instruments, such as miniature ball bearings (1–10mm bore) and thin-section bearings, provide high-precision, low-friction, and reliable performance in restricted spaces. Key options include stainless steel for corrosion resistance, ceramic for high speed/temperature, and 2RS (rubber seal) types to protect against contaminants, suitable for diagnostics, centrifuges, and medical devices.

Key Features and Types

Miniature Ball Bearings: Crucial for small-scale applications like medical handheld devices, featuring bore sizes under 10mm.
Thin Section Bearings: Used in compact medical and laboratory equipment where space is limited.
Sealing Options: Rubber seals (2RS) provide better protection against contamination and moisture, which is crucial for hygienic and laboratory environments.
Materials: Stainless steel (e.g., AISI 440C or specialized corrosion-resistant grades) is commonly used to withstand cleaning and sterilization processes.
Performance: These bearings (often ABEC-5 or higher) provide low friction and low noise, essential for high-speed motors and sensitive diagnostics.

Common Applications in Laboratory Instruments

Medical Diagnostic Equipment: Used in analyzers, centrifuges, and portable devices.
Robotic Surgical Tools: Require high-precision motion in constrained spaces.
Dental Handpieces: Need durable, high-speed, and sealed bearings.
Laboratory Automation: Used in robotic handling and flow meters.

Common Specifications

Common Series: 6700 series (ultra-thin), 6800, 6900, and 6000 series.
Seal Type: 2RS (two rubber seals) or ZZ (two metal shields) for maintenance-free operation.

For specialized requirements, such as high-temperature or autoclaving in labs, ceramic or high-grade stainless steel bearings are recommended.
