AUZHU- BRF - Metric- Double Bearings with Housing, Aluminium Alloy Round Flange Seat, Configurable Length, Deep Groove Ball Bearings with Retaining Ring Size: D 3 mm, L 20 mm, Bearing No.623

About this product: * Flange holders for bearing housings are available in aluminium alloy, carbon steel and stainless steel. Flange holders of each material are available in three shapes: round, square and compact H-shape. Each shape of flange holder has several sizes to choose from. We can meet customers' requirements for flange holders of different materials, strengths, shapes and sizes, so that the products can adapt to a wider range of use environments. * If you do not require high strength and rigidity of the flange bracket, aluminium alloy material is more comparatively lightweight and can meet your requirements. If the bearing housing needs high load and has higher requirements for strength and rigidity, it is recommended to choose steel or stainless steel material. If the housing is used in food industry, high humidity environment or outdoor, stainless steel will be more suitable for you. * Scope of application: the support of this bearing housing is made of carbon steel, with high precision, high strength, high rigidity, wear-resistant, durable and other properties. It can be widely used in factory automation standard parts, MRO, manufacturing processing, electronic and electrical equipment, ships, military aviation, decorative hardware, industrial manufacturing, precision equipment plastic moulding and other industries. * We are a factory, if you need more special hardware parts, we can provide customized processing services. We can customize the style and size you need according to the customer's drawings or requirements, and welcome your letters.

• BRF is the model number for this product. The dimensions you have selected are: shaft bore inner diameter D of 3 mm, housing height L of 20 mm, bearing number No.623. Different capital letters are used in the product drawings to represent the dimensions of the various detail positions on the product. The specific dimensional data can be found under the corresponding letters in the specification sheet, and several sizes are available.
• [Material of bearing: Steel]; [Material of flange bracket: Steel]; [Surface treatment of flange bracket: Black Oxide]; [Material of grommet: Stainless Steel].
• Design structure: This product is a double bearing type housing assembly with circlips. The two bearings in the housing are deep groove ball bearings with high dimensional accuracy of the bearing bore diameter. The circlip design provides greater stability and prevents the bearings from falling out at high speeds. The flange bracket is equipped with mounting holes, which contributes to accurate positioning and stable mounting.
• Before ordering, please accurately measure the diameter of the shaft used, the shaft diameter should be negative tolerance. This bearing housing has high dimensional accuracy of the inner diameter of the shaft hole and high perpendicularity and coaxiality, which makes the shaft centre smoother when the transmission shaft is rotating. They are suitable for use in machinery and equipment that require high precision, heavy loads, or transmission products that use rotating shafts.
• Warm reminder: the data on this page are in metric millimetres. As the sizes are measured manually, there may be a slight error, but the error will be less than ±0.5 mm, please understand.
