Frequently Asked Questions

Q: What is the difference between R12ZZ and R12-2RS deep groove ball bearings?

A: R12ZZ bearings feature double metal (steel) shields on both sides, which are ideal for dry, high-speed environments where minimal friction is needed. R12-2RS bearings have rubber seals on both sides, offering better protection against dust and moisture — making them suitable for slightly contaminated or humid environments.

Q: What machines are R12 deep groove ball bearings compatible with?

A: R12 bearings (3/4" inner diameter, 1-5/8" outer diameter, 7/16" width) are compatible with a wide variety of equipment including electric motors, power tools, RC models, fitness machines, and precision instruments. Always verify your equipment's bearing seat dimensions before ordering.

Q: Can I order R12 bearings in bulk or request a custom type?

A: Yes! Wholesale and bulk orders are fully supported. If you need a different bearing model or have specific quality requirements, please reach out directly — professional supply arrangements for businesses are available.
