Good Quality Ball Bearings Mini Bearings 626zz 626-2rs

Miniature ball bearings are deep groove ball bearings in small. Their dimensions make them suitable for special applications. In addition, they allow very high speeds with low noise.

Versions of miniature ball bearings

Single row

Main dimensions according to DIN 625-1. Inside diameter below 10 mm. Economical "all-round bearing". Versatile.

Miniature flanged housing units

For simplified locating bores in which the bearing is supposed to be axially fixed. Inside diameter below 10 mm.

Full complement ball set

Without a cage and maximum number of balls, higher load carrying capacity than caged miniature ball bearings of the same size.

Material description of miniature ball bearings

Miniature ball bearings made of rolling bearing steel

are extremely economical, withstand extremely high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.

Miniature ball bearings made of stainless steel

are hygienic, corrosion-resistant, lubricated with grease for the food industry, offer high load-ratings, magnetic and are admissible for a temperature range from circa -20°C up to +120°C, in case of rubber seals up to circa +100°C in the long run.

Hybrid bearings with ceramic balls and rings made of stainless steel or rolling bearing steel

are subject to a lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are current insulating - optimally for use in engines and generators. Hybrid bearings are lighter than bearings with steel balls of the same size, withstand higher speeds and operate in a temperature range from circa -20°C up to +130°C, in case of rubber seals up to circa +100°C in the long run. Hybrid bearings are magnetic.

Miniature ball bearings made of ceramic

are extremely wear-resistant by their great hardness, corrosion-resistant and durable. They have good emergency running characteristics, are lighter than steel bearings of the same size, suitable for dry run, current insulating, non-magnetic, withstand extremely high speeds. Bearinngs with cages made of PTFE operate up to a temperature of circa +160°C, bearings with cages made of PEEK up to a temperature of circa +160°C.
