Frequently Asked Questions
Q: What is the speed limit for the BS 5205 ZZ bearing?
A: The BS 5205 ZZ has an approximate speed limit of 7,300 RPM. Do not exceed this speed rating, as doing so will cause premature bearing failure and heat generation.
Q: What materials are used in this bearing?
A: The bearing raceways and balls are made from high carbon chrome steel. The cage is constructed from polyamide 66, a durable synthetic material that reduces friction and extends bearing life.
Q: What is the difference between ZZ and 2RS seals?
A: ZZ designates metal shields on both sides that provide light contamination protection at higher speeds. 2RS uses rubber seals for better sealing in wet or dirty environments but has lower speed ratings. Choose based on your operating environment and speed requirements.
Q: What applications is the BS 5205 ZZ suitable for?
A: This bearing is designed for manual pallet jack parts and general machinery applications requiring moderate speed operation. It provides a balance between contamination protection and rotational performance in typical warehouse and light industrial settings.
Q: How does this bearing perform in cold storage or wet conditions?
A: The metal ZZ shields offer minimal moisture protection compared to rubber seals. For frequent exposure to wet floors or cold storage below 32 degrees Fahrenheit, consider a 2RS seal variant for better performance and longer service life.
