China Ball Bearings 鈼?Introduction Single row deep groove ball bearings is the most common rolling bearing, and its bearing type code is 6 with a simple structure. Its open bearing is made of an inner ring, an outer ring, a set of cages and a set of steel balls. There are many changes in its size range and form, so it is easy to achieve high precision and facilitate mass production in series. The cost of bearings is low, it is convenient to use and maintain, and it is widely used. The bearing has a small friction coefficient and a high limit speed, and mainly bears radial loads. At the same time, the bearing can also bear some axial loads. At high speeds, it can be used to bear pure axial loads. In addition to open bearings, there are bearings with dust cover, including Z type and 2Z type, bearings with seal rings, including RS type, 2RS type, RZ type and 2RZ type. Bearings with seals and bearings with dust cover have basically the same purpose. The difference between them is that the bearing with sealing ring seals better, but the friction is increased. The external dimensions of the single row deep groove ball bearings accord with DIN 625-1, the dimensional tolerances and rotational accuracy accord with standard DIN 620. Deep groove ball bearings can be used in precision instruments, motors, automobiles, motorcycles, gearboxes, machine tool gearboxes, household appliances, tools and mechanical equipment. Bearings with dust cover are mostly used at both ends of rotors of small and medium generators, motors, automobiles, tractors, air conditioners, fans, etc. 鈼?Bearing Series The types of the deep groove bearing include 6000 series, 6200 series, 6300 series, 6400 series, 61800 series, 61900 series, 62200 series, 62300 series and 16000 series.

Standard parts: inner diameter, outer diameter, angle, groove diameter, raceway, roller, steel ball standard parts, etc. 2. Template: raceway position template, taper diameter template, angle template and curvature radius template, etc. 3. Limit gauges: smooth plug gauge, outer diameter caliper, groove diameter caliper, etc. 4. Measuring ruler: inner diameter, outer diameter, raceway diameter, model ruler, etc. 5. Other measuring tools: mandrel, tapered roller sleeve, measuring table, etc. 鈼?Bearing Ring Blank Machining Bearing ring blank machining is the first process of bearing production. The quality and productivity of the ring blank play an important role in the quality, performance, life and economic benefits of the bearing products. This is because the size of the blank margin determines the utilization rate of the bearing material; the internal quality of the ferrule includes the density of the material, the streamline distribution of metal fibers, grain size and deformation heat treatment, etc., which have a greater impact on the bearing life; then The main reasons for the high rejection rate, the failure of normal automatic production and the impact on the processing quality of subsequent processes are the dispersion of blank dimensions and poor geometric accuracy. The blank processing technology, equipment accuracy and performance determine the blank quality. The production process of the bearing ring is as follows: bar or tube (some bars need to be forged, annealed, and normalized) 鈫?turning 鈫?heat treatment 鈫?grinding 鈫?fine grinding or polishing 鈫?final inspection of parts 鈫?anti-rust 鈫?warehousing 鈫?to be assembled. 鈼?Standard 鈼?ISO 15: Rolling bearings - Radial bearings - Boundary dimensions, general plan 鈼?ISO 76: Rolling bearings.
