Types of bearing steel miniature ball bearings include: 1. There are 7 types of deep groove ball metric 68 series, 69 series, 60 series, MR series and inch R series. Based on this, they can also be divided into dust cover with ZZ steel plate. Bearing series, miniature bearing series with RS rubber seal ring, Teflon bearing seal ring series and flange flange series, etc. Second, bearing steel miniature plane thrust bearings are divided into channeled and non-channeled. Main uses: elevator accessories / plastic machinery crane hooks, vertical water pumps, vertical centrifugal pumps, low speed reducers, automobile steering mechanisms, etc. The bearing's shaft washer, seat washer and rolling element are separated and can be assembled and disassembled separately. Third, the connection between the steel ball of the miniature angular contact ball bearing and the contact point of the inner and outer rings is at an angle to the radial direction. The contact angle is generally divided into 15 °, 30 °, and 40 °, which are represented by the letters C, A, and B, respectively. Angular contact bearings are used in engineering design for high speed and high precision, and are suitable for: agriculture; chemistry; general industry.
Bearing steel miniature ball bearings refer to all kinds of bearings with metric series and inner diameter less than 9mm; inch series with inner diameter less than 9.525mm! The smallest inner diameter can be 0.6mm, and the inner diameter is generally more than 1mm.
Bearing steel miniature bearings are suitable for various industrial equipment, small rotary motors and other fields with high speed and low noise, such as: office equipment, micro motors, instruments, laser engraving, small clocks, soft drives, pressure rotors, dental dental drills Hard disk motors, stepper motors, video recorder drums, toy models, computer cooling fans, money counters, fax machines and other related fields.
Bearing steel miniature ball bearings are ideal for compact, high-performance designs that can run at low friction and high speed, and minimize subsequent maintenance requirements. These silent running bearings are rugged and durable, can withstand light to moderate radial and thrust loads, and are available in many types and designs. As well as a variety of different lubrication options, miniature angular contact ball bearings can simultaneously bear radial and axial loads.
