Brass cages have good processing properties and formability, making them a commonly used bearing cage material. The brass cage ensures that the bearing will not deform or fall off when rotating at high speed, and there will be no complex friction between the rolling elements and the cage, making the bearing work more smoothly.
This type of bearing has small friction coefficient, high rotational speed, simple structure, low manufacturing cost, and relatively easy to achieve high precision. It mainly bears radial load, and can also bear a certain amount of axial load. Compared with other types of deep groove ball bearings of the same size and size, this type of bearing has a small friction coefficient and a high limit speed. However, it is not shock resistant and not suitable for heavy loads.
Miniature bearings refer to various types of bearings in the metric series, with an outer diameter less than 9mm; in the imperial series, with an outer diameter less than 9.525mm! The main materials include carbon steel, bearing steel, stainless steel, plastic, ceramics, etc. The minimum inner diameter can be 0.6mm, and generally the inner diameter is 1mm.
Thickened deep groove ball bearings
Deep groove ball bearings are suitable for high-speed and even extremely high-speed operation, and are very durable and do not require frequent maintenance. This type of bearing has small friction coefficient, high limit speed, and various size ranges and forms. It is used in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the machinery industry. It mainly bears radial load and can also bear a certain amount of axial load.
Ordinary deep groove ball bearings are easy to rust when used for a long time or in places with a lot of water vapor. The friction of the steel balls of ordinary deep groove ball bearings has a great influence on the speed, making it difficult to meet high speed requirements. - Speed app.
Flange deep groove ball bearings are used in a wide range of applications, from printers to monitors.
Ball bearings with snap groove and snap ring
Deep groove ball bearings with stop grooves in the outer ring can be positioned with stop rings. During installation, the bearing can be easily fixed on the bearing seat. Therefore, when the axial installation position is limited, it should be preferred. According to the different characteristics of the bearing application, various combinations of dust covers, sealing rings, stop grooves, etc. can also be realized.
Ball bearings with ball grooves
The deep groove ball bearing with a ball mouth is a special structure bearing with a ball mouth without a cage, a large number of steel balls, and a certain amount of locking in the inner and outer rings. There are two main designs: open or with guards on one or both sides. In addition, the bearings are available with or without retaining grooves. The outer ring of the open bearing has grooves and a dust cover can also be installed. Due to the large number of steel balls and high load-bearing capacity, deep groove ball bearings are widely used in large-load transmission components such as aviation and aerospace.
High temperature ball bearings
Ordinary deep groove ball bearings can meet most applications, but in some special places, such as extremely cold and hot environments, ordinary bearings cannot be used. As a result, high-temperature bearings were invented.
Thrust roller bearings are used to bear the combined axial and radial loads with the main axial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed and self-aligning performance.
