Frequently Asked Questions
What makes the 608ZZ suitable for high-speed applications?
The bearing’s low-friction chrome steel construction, combined with high-precision matching of internal components, supports speeds up to 34,000 RPM, ideal for fast-rotating assemblies.
Can I use the 608ZZ in outdoor environments?
Yes. The stainless steel shields and cage, along with corrosion-resistant construction, enable reliable performance even in humid or variable conditions.
What’s the difference between 608ZZ and 608 open/2RS bearings?
-
608ZZ: Double metal shields—dust protection, grease retention
-
608 (open): No shields—easy relubrication, no contamination resistance
-
608-2RS: Rubber seals—better moisture protection, slightly more drag
Do you offer OEM or bulk purchasing?
Absolutely. We provide:
-
OEM branding and packaging
-
Bulk pricing for distributors
-
Engineering support for large-scale applications
