Deep Groove Ball Bearings — 481+ Models (MR, 67/68/69, 60/62/63/64, F, S, R)

Why Deep Groove Ball Bearings?

Deep groove ball bearings handle radial loads and moderate axial loads in both directions with very low friction, low noise and high speed. Simple, robust and cheap at scale — the default choice for motors, pumps, fans and appliances.

Materials available:

GCr15 / AISI 52100 — Standard 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?

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