Durable Zinc Alloy Material - The 20mm housing bearing is made of high quality zinc alloy ,rust and corrosion resistant, strong and durable. The inner and outer rings have high precision, wear-resistance, strong load capacity, high temperature resistance, will not get hot easily and can work stably and efficiently for a long time. Ball Bearing Pillow Block Set - Contains 2 pcs KP004 pillow block bearings, each pillow block bearing has an inner diameter of 20mm, the mounting hole diameter is 10mm,the linear distance between the two holes is 80mm and the base length is100mm,used to make the metal bearings for maintain and replace 3D printer supplies. Adjustable Angle - Vertical pillow block bearing has a centrifugal fine-tuning design to ensure that the housing bearing always maintains a correct angle during operation, which is beneficial for reducing friction and achieving smooth and efficient operation. Inside the Bearings Block there are high-strength rolling elements, the speed is constant during operation and noise is reduced. Easy to Install and Attach - Since the housing bearing uses a double screw socket and ball bearing inserts, it is very easy to install and remove. The bearings block has a wide inner ring with built-in mounting screws. You can adjust the screw clamping ring so that it is firmly connected to the guide shaft to ensure a stable connection between the pillow block bearing and the drive shaft. Multifunctional Housing Bearing- Zinc Alloy Flange Bearing Block are self-aligning seated pillow block bearings that have the advantages of high speed, low noise and not easy to burn. It can be adapted to most machines and is suitable for aerospace, industrial automation, compressors, machines, fitness equipment, water pumps, motors, agricultural machinery, etc. Product 2 PCS 20mm Pillow Block Bearings are made of strong and wear-resistant zinc alloy , the unique centrifugal design ensures high speed, high efficiency and no heat and big noise, it is a core accessory in the field of industrial manufacturing. KP004 Vertical Flanged Bearings: The specification of the flange bearing bracket is KP004, the bore diameter is 20mm and the fixed hole diameter is 10mm. Vertical flange bearings are used in various industrial sectors, such as: electromechanics, aerospace, aviation, trucks, automobiles, construction machinery, CNC machine tools. Strong and robust: The Bearing Pillow Block is made of high quality zinc alloy materials with uniform hardness and wear resistance, and will not get hot even after prolonged use, it is an ideal choice for metal bearing kits used for maintenance and replacement of 3D printer accessories. Increase efficiency: The self-aligning design allows the angle between the inner housing bearing and the outer mounting ring to be fine-tuned to ensure that the bearing is more efficient in operation. Vertical housing bearings are easy to install and remove, saving you time and effort. Scope: High quality vertical flange bearings are characterized by high speed, low noise and stable operation and can be applied to various machines: motors, water pumps, air conditioners, sewing machines, massage chairs, agricultural machines, fitness equipment, metallurgical machines, etc. Specification: Name: pillow block bearing Material: zinc alloy Model: KP004 Aperture: 20mm Quantity: 2 pcs Package Including 2 x Bearing Pillow Block
