Stainless Steel Miniature Bearings
Product Overview
Stainless Steel Miniature Bearings are designed for compact equipment that requires improved corrosion resistance, cleanliness, and reliable rotation in humid, frequently cleaned, or mildly corrosive environments. They combine miniature deep groove bearing geometry with stainless steel rings and rolling elements for small shafts and limited installation spaces.
These bearings can support radial loads and limited axial loads in both directions while maintaining low friction and stable operation. Open, shielded, and sealed structures are available, together with food-grade, low-noise, wash-resistant, and temperature-specific lubrication options.
ETM supplies stainless steel miniature bearings for medical equipment, food and beverage machinery, robotics, home appliances, office equipment, instruments, and compact motors. OEM options include dimensions, material grade, precision, clearance, sealing, lubrication, noise level, marking, cleaning, and packaging.

FAQs
Why choose stainless steel miniature bearings?
They provide improved corrosion resistance and clean operating performance for compact equipment exposed to humidity, cleaning, handling, or mildly corrosive environments.
Are stainless steel miniature bearings completely rustproof?
No bearing is completely rustproof in every environment. Performance depends on stainless grade, moisture, chemicals, temperature, cleaning method, lubrication, storage, and maintenance.
Can food-grade grease be supplied?
Yes. Food-grade and application-specific grease options can be supplied when required, subject to speed, temperature, load, and compliance requirements.
Which seal or shield type should I use?
Use open bearings for very low torque or external lubrication, ZZ shields for low-friction particle protection, and 2RS seals for stronger contamination protection and grease retention.
What applications use stainless miniature bearings?
They are commonly used in medical equipment, food and beverage machinery, robotics, home appliances, office equipment, instruments, compact motors, and clean mechanisms.
Can ETM provide customized stainless miniature bearings?
Yes. ETM can customize dimensions, material grade, precision, clearance, closures, lubrication, cleaning, noise level, marking, packaging, and batch supply.
