Product Q&A

Q:Are you a factory or trading company?

We are a professional manufacturer with our own export team. We control production, quality and delivery directly, so you get competitive price and reliable service.

Q:What precision grades do you offer for RA bearings?

We offer P5 (ABEC-3), P4 (ABEC-5/7), and P2 (ABEC-9) precision grades. Standard stock is P5; P4 and P2 are available for most common sizes with a slightly longer lead time.

Q:Are RA bearings preloaded?

Yes. All our RA bearings come with factory-applied preload (Light, Medium, or Heavy). No field adjustment is needed. For zero-preload (free-play) applications, open-clearance models are also available.

Q:Do you offer sealed RA bearings?

Standard RA series is available in open configuration. Select models are available with RS seals (non-contact metal shields on one side) for contamination protection. For full environmental sealing, please contact us for custom specifications.

Q:Can you manufacture RA bearings in stainless steel?

steel? Yes. While standard material is GCr15 (AISI 52100) through-hardened bearing steel, we offer AISI 440C stainless steel versions for corrosion-resistant and clean-room applications (medical, semiconductor, food & beverage).
