Miniature deep groove ball ceramic bearings

POM (polyoxymethylene) operating temperature range is from - 60°C to 100°C. Due to its high surface strength and smoothness, POM has excellent sliding properties and wear resistance. POM basically does not experience tension, and its copolymer has high thermal stability and chemical stability (it is worth paying special attention to its enhanced hydrolysis resistance) PA polyamide (nylon) is a high-precision engineering plastic, and polyamide has High strength, hardness and toughness, as well as high heat resistance and non-deformation (about 40°C to 100°C). Since good mechanical properties can only be achieved after the material temperature is suitable, it must be humidified again after annealing and grown in the air. Time storage can also reach the corresponding temperature.

Product Description

Product Details

Miniature deep groove ball ceramic bearings refer to the metric series, with an outer diameter less than 9mm; the inch series, with an outer diameter less than 9.525mm, are mainly made of ceramics, and the smallest inner diameter can be 0.6mm, and most of them have an inner diameter of 1mm. Among the ultra-small diameter micro bearings, the types of micro deep groove ball ceramic bearings include the metric 68 series, 69 series, 60 series, etc., and the imperial R series, a total of 6 types, which are suitable for high speeds such as various industrial equipment and small rotary motors. Low-noise areas, such as: office equipment, micro motors, instrumentation, laser engraving, small watches, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, video recorder drums, toy models, computer cooling fans , money counting machines, fax machines and other related fields.
