Materials available:

GCr15 / AISI 52100 — 标准系列 chrome bearing steel (default)
AISI 440C Stainless — Corrosion-resistant (S-series)
Hybrid ceramic (Si3N4 balls + steel rings) — Available on request for high-speed / low-friction applications

Tolerance classes: P0 (ABEC-1) standard; P6 (ABEC-3) / P5 (ABEC-5) available for precision motor use.

Closures: Open (no seal), ZZ (metal shield), 2RS (rubber seal).

Cage types: Stamped steel (standard), reinforced nylon (low-noise option), brass (high-temp).

Note: Dynamic load rating (Cr) and static load rating (Cor) are calculated from nominal dimensions per ISO 281; limiting speeds are reference values for grease / oil lubrication. Stainless (S) ratings use AISI 440C. Figures are for preliminary selection only — confirm exact values against our official catalog before ordering.

FAQ

Can you match a standard size like 6203-2RS?

Yes - all common 60/62/63 sizes are in regular production; send the code for a quote.

Do you offer low-noise grades?

Z2 and Z3 noise grades are available for quiet motor applications.

Rust protection for sea freight?

Anti-rust oil plus moisture-proof, shock-resistant export packaging.

Do you supply miniature bearings below 3 mm bore?

Yes — our MR series starts at MR52 (bore 2 mm), and we can supply 1.5 mm and smaller on request. MR52 through MR148 are in stock for immediate shipment.

What is the difference between ZZ and 2RS seals?

ZZ = metal shield (non-contact, higher speed limit, basic dust protection). 2RS = rubber contact seal (better moisture/dust exclusion, slightly lower max speed). For dry indoor motors: ZZ is fine. For humid or dusty environments: choose 2RS.

Can I get stainless steel in MR or 68 series sizes?

Yes — our S-series covers popular miniature sizes (S684–S699, S605–S609) in AISI 440C stainless steel. Other sizes available as custom orders (MOQ varies by size).

What is your MOQ for a single MR model like MR85ZZ?

标准系列 miniature sizes: 1000 sets per model. Mixed-model orders (same series, different sizes): 500 sets minimum total. Custom / non-standard: 100 sets.
