624 Bearing (Open / ZZ / 2RS) | Premium Miniature Ball Bearing
624 bearing is a popular miniature single-row deep groove ball bearing with standard 4mm×13mm×5mm dimensions. This high-performance 624 miniature bearing features low friction, ultra-quiet stable rotation, and excellent radial and light axial load capacity. We supply three mainstream 624 bearing types: 624 Open, 624ZZ double metal shield, and 624 2RS double rubber seal. Available in 5 industrial-grade materials including bearing steel, 420 stainless steel, 440 stainless steel, 403 stainless steel, and 316 stainless steel, the versatile 624 bearing is widely applied in micro motors, precision instruments, drone parts, medical devices, and small automated machinery.
624 Bearing Types: Open / ZZ / 2RS
1. 624 Open Bearing
624 Open bearing adopts an unsealed open structure with zero running resistance and outstanding heat dissipation. This 624 open bearing supports ultra-high-speed continuous operation, ideal for clean, dry working environments with regular lubrication maintenance.
Applications: High-speed micro motors, precision testing instruments, clean industrial transmission components.
2. 624ZZ Bearing
624ZZ bearing is equipped with double non-contact metal shields, effectively blocking dry dust and fine particle impurities. The 624ZZ miniature bearing retains low friction and high temperature resistance, delivering stable performance and high cost performance for dry indoor working scenarios without waterproof demands.
Applications: Electric tools, toy motors, household appliances, office equipment, dry automated industrial machinery.
Applications: Outdoor miniature equipment, cleaning machinery, agricultural parts, food processing equipment.
624 Bearing Material Introduction And Applications
1. Bearing Steel (GCr15/52100)
Bearing steel 624 bearing boasts high hardness, superior wear resistance and strong load capacity. As the standard 624 bearing model, it ensures high precision and cost efficiency for dry high-speed mechanical applications, while lacking corrosion resistance for harsh environments.
2. 420 Stainless Steel
440 stainless steel 624 bearing offers the highest hardness among stainless steel options, with excellent wear resistance and mild corrosion resistance. It is the ideal high-precision 624 bearing for medical devices, waterproof electronics and light-load marine components.
5. 316 Stainless Steel
High-speed clean conditions: 624 Open + Bearing Steel
High-temperature industrial applications: 624ZZ/2RS + 403 Stainless Steel
