Questions & answers
What types of bearings does HCH mainly produce?
“HCH produces six core precision bearing series: Deep Groove Ball Bearings, Flexible/Thin-Section Bearings, Miniature/Micro Bearings, Four-Point Contact Bearings, Tapered Roller Bearings, Crossed Roller Bearings. Annual output exceeds 800 million units.”
How do I choose the right bearing type?
“Consider load type, space constraints, accuracy requirements, speed, and environment. Contact james@hchbearing.com for free selection proposal.”
Difference between flexible and crossed roller bearings?
“Flexible bearings: ultra-thin, 30-50% lighter. Crossed roller: orthogonal cylinders, ≤0.005mm accuracy, higher rigidity. Both used in harmonic reducers.”
What do bearing accuracy grades mean?
“P0 normal, P6 medium, P5 high, P4 ultra-precision, P2 highest. HCH produces P0-P2 with CNAS-accredited lab.”
What quality certifications does HCH hold?
“IATF 16949, ISO 9001, CNAS-Accredited Laboratory, Zhejiang SRDI Enterprise.”
What materials are used?
“Standard: GCr15 bearing steel. Options: 440C stainless steel, DLC coatings, chrome plating.”
How long do HCH bearings last?
“Design life 20,000-50,000 hours under standard conditions. 30+ life testing machines verify reliability.”
What is the Minimum Order Quantity?
“Standard: 100-500 units. Custom: from 1,000 units. Free samples available.”
What is the delivery lead time?
“Standard: 3 days (urgent 24h). Custom: 2-4 weeks (expedited 1-2 weeks).”
